Canadian HELOC or refinance to finance a Florida purchase

60-second summary

You are Canadian, a Canadian tax resident, and you are considering buying property in Florida. You already own a principal or secondary residence in Canada, substantially free of mortgage debt, or with a modest residual mortgage. Three orthodox financing paths exist on the U.S. side: a cross-border loan from a Canadian bank's U.S. subsidiary, a Foreign National Loan from a U.S. private lender, and a cash purchase. The fourth path, covered here, funds the cash purchase: tapping Canadian home equity to produce funds in CAD, converting to USD at closing, and paying cash in Florida.

The Canadian federal framework allows three instruments. First, a Home Equity Line of Credit (HELOC) alone, capped at 65% LTV by OSFI Guideline B-20. Second, a combined amortizing-mortgage-plus-HELOC product, with a total capped at 80% LTV. Third, a conventional refinance of the existing mortgage, also capped at 80% LTV without mortgage insurance. The seven main Canadian institutions offer all three instruments under different brand names: RBC Homeline Plan, TD Home Equity FlexLine, BMO Homeowner ReadiLine, Scotia Total Equity Plan (STEP), CIBC Home Power Plan, National Bank All-in-One, Desjardins Marge Atout.

The economic arbitrage is not automatic. The path eliminates the U.S. lender, the 1 to 2 point foreign-national premium, U.S. lender fees (origination, points, processing) and U.S. title insurance on the financing. It creates a permanent CAD/USD currency exposure that can cut either way. Canadian tax treatment of HELOC interest depends on the use of funds: no Canadian deduction if the Florida property is a personal second home; deductibility against rental income if rented. On the U.S. side, the Canadian debt is not U.S. debt, generates no FBAR for a Canadian without U.S. status, and does not affect the taxation of the property itself.

Glossary

Core acronyms are defined in the block at the top. Three concepts deserve elaboration because they are often confused.

HELOC versus amortizing mortgage. A conventional Canadian mortgage is amortizing: the balance is reduced each month per a predefined schedule. A HELOC is revolving credit secured by a mortgage charge: the balance fluctuates with draws and repayments, much like a credit card backed by your home. A HELOC rate is almost always variable, indexed to the Canadian prime rate. A combined product holds both in a single registered instrument, with an amortizing portion and a revolving portion.

Combined LTV versus HELOC portion LTV. When B-20 caps the "HELOC alone" at 65%, it means the revolving portion (drawable on a non-amortizing basis) cannot exceed 65% LTV. When it caps "combined" at 80%, that is the sum of the amortizing mortgage plus HELOC. Concretely: on a property appraised at CAD 600,000, you can have a standalone HELOC up to CAD 390,000 (65%), or a combined product up to CAD 480,000 (80%), structured for example as CAD 290,000 amortizing plus CAD 190,000 HELOC.

Conventional refinance. A refinance is not a line. It is a new amortizing mortgage that replaces the old one, generally at a new rate and a new term. The new mortgage can be higher than the old one, up to 80% LTV without mortgage insurance. The incremental amount finances whatever the borrower chooses, including a Florida cash purchase. Refinancing often triggers a breakage penalty on the existing mortgage (interest rate differential or three months' interest, depending on the contract), which must be folded into the arbitrage.

Why this article exists for a Canadian

This financing path is dominant in practice yet almost invisible in public discussion. Per the National Association of REALTORS for the 12 months ending March 2025, 57% of Canadian buyers of U.S. real estate paid cash. These are not, in most cases, buyers pulling USD 600,000 out of a chequing account. They are established Canadian property owners who mobilized the equity of their Canadian property to produce the cash payment.

No official source breaks down those 57% precisely. A fraction comes from accumulated savings and portfolio liquidity (planned RRSP drawdowns, non-registered accounts, sale of other assets). A material fraction comes from HELOCs, principal-residence refinances in Canada, or combined products such as the Scotia Total Equity Plan or the RBC Homeline Plan. In the practice of Quebec and Ontario mortgage brokers who serve a snowbird clientele, the typical scenario is: Canadian principal residence fully paid, combined line increased toward the B-20 cap, CAD-to-USD conversion at closing, cash closing in Florida.

This article explains why this path dominates in practice, how it works mechanically, what it actually costs, and under what conditions it wins or loses the economic arbitrage against the two other paths (cross-border and Foreign National). It is written for a Canadian who already holds meaningful equity in their Canadian property, who can document Canadian income, and who can pass the B-20 stress test. If you do not yet own property in Canada, or if your available equity is less than CAD 200,000, this path is less relevant and a cross-border or Foreign National loan on the Florida property will be more logical.

The article is also not written for Canadians who hold a Green Card or who have become U.S. tax residents under the Substantial Presence Test. Those readers are "U.S. persons" under the IRS and their position triggers FBAR, FATCA and U.S. tax treatment of Canadian debt, which is beyond the scope of this guide. For that profile, see a cross-border tax specialist first.

The OSFI B-20 framework: the 65% and 80% caps

OSFI Guideline B-20 governs underwriting of residential mortgages in Canada. It applies to federally chartered institutions, which covers the six big Canadian banks (RBC, TD, BMO, Scotiabank, CIBC, National Bank) and several specialist lenders. In Quebec, Desjardins sits under the Autorité des marchés financiers (AMF), but the AMF has adopted standards aligned with B-20.

Three B-20 rules matter for this financing path. First rule: a HELOC alone, that is the revolving non-amortizing portion, cannot exceed 65% LTV for an uninsured loan. Second rule: the combined amortizing-mortgage-plus-HELOC portion cannot exceed 80% LTV for an uninsured loan. Third rule: the stress test applies to any new origination, any line increase, and any refinance. The borrower must qualify at the higher of contract rate plus 200 basis points or the minimum qualifying rate published by the Bank of Canada.

Three practical nuances often escape a quick read of B-20. First nuance: the 80% cap relates to LTV at the time of underwriting, on the appraisal value at that point. If the property appreciates, your mechanical LTV declines, but your line limit does not automatically rise. A limit increase requires a new appraisal and a new stress test. Second nuance: the stress test runs against the entire mortgage debt of the file, not just the marginal increase. If you raise your combined line to fund a Florida purchase, the test covers your total Canadian debt service, not just the incremental amount. Third nuance: B-20 says nothing about the destination of funds. Whether you use the line to buy a vehicle, finance renovations, or close cash in Florida, the prudential framework is the same. Use of funds matters to the tax authority, not to OSFI.

The three Canadian products you can use

Three Canadian instruments can produce the funds needed for a Florida cash purchase. They are not equivalent, and the arbitrage between them depends on your current file.

Product 1: standalone HELOC

A standalone home equity line of credit, without amortizing portion, is capped at 65% LTV by B-20. On a property appraised at CAD 600,000 free and clear, you can open a standalone HELOC up to CAD 390,000. The rate is almost always variable, indexed to the Canadian prime rate plus a markup (typically prime plus 0.5 to 1 percentage point for an average file). Monthly service in most products is interest-only with no mandatory amortization. This product offers maximum flexibility: you draw what you need at the time of the Florida closing, you repay at will, you redraw as needed. The trade-off: the rate floats and service does not mechanically reduce principal.

Product 2: combined line (amortizing mortgage plus HELOC)

A combined product holds an amortizing portion and a revolving portion in a single registered instrument (in the Land Registry of Quebec or the equivalent registry elsewhere in Canada). The total is capped at 80% LTV. On the same CAD 600,000 property, you can reach CAD 480,000 total. Typical configuration: CAD 290,000 in an amortizing mortgage at fixed or variable rate, plus CAD 190,000 in HELOC. As the amortizing portion pays down, the available HELOC limit can readjust upward in some products (Scotia STEP), or stay fixed (TD Home Equity FlexLine without automatic readvancement).

This is the canonical product for the HELOC-to-Florida path. The amortizing portion produces the bulk of the funds at a lower rate than a standalone HELOC (ARM or fixed rather than prime-plus), and the revolving portion serves as a reserve for closing costs, first-year Florida contingencies, or improvements.

Product 3: conventional refinance

A refinance replaces your current Canadian mortgage with a new amortizing mortgage, generally at a new rate and a new term. The new mortgage can be higher than the old, up to 80% LTV without mortgage insurance. On the CAD 600,000 property with a residual mortgage of CAD 100,000, you can refinance up to CAD 480,000; the CAD 380,000 difference is paid out in cash and finances the Florida closing.

Refinance typically produces the lowest rate of the three products, because it is fully amortizing and lenders offer their best terms on this product. The trade-off: it almost always triggers a breakage penalty on the current mortgage (interest rate differential or three months' interest, per the contract), it kicks off a new stress test on the total new loan, and it locks in the term (typically 5 years); you cannot easily increase before the next renewal.

Maximum LTV by Canadian institution

The table below summarizes the maximum LTV each of the seven main Canadian institutions publishes for its HELOC, combined and refinance products. Figures come from the official product pages, consulted on May 14, 2026. All percentages reflect compliance with OSFI B-20 (or the aligned AMF standard for Desjardins).

Verified fact. All seven main institutions offer the maximum combination of 80% LTV combined plus 65% LTV HELOC alone, in compliance with B-20. Differences emerge in the advertised variable rate, prime-plus markup, breakage penalty, automatic-readvancement flexibility on principal repayment, and service quality. The Scotia STEP stands out for its ability to subdivide into multiple subaccounts within a single global limit. The RBC Homeline is reputed for the speed of approval when the file is already with RBC. The Desjardins Marge Atout is the reference option for a Quebec Desjardins member.

Verified fact. All federally regulated institutions (RBC, TD, BMO, Scotia, CIBC, National Bank, Tangerine) sit under OSFI B-20. Desjardins, under AMF regulation (Quebec), applies caps aligned with the federal standard and explicitly cites compliance with "Guideline B-20" in its product documentation.

Opinion. For an average file with a free-and-clear Canadian principal residence, the combined product at your main bank is almost always the right call. The rate differential among the seven institutions is generally less than 25 basis points on the amortizing portion and less than 25 basis points on the HELOC markup, and the administrative cost of switching institutions (appraisal, legal fees, mortgage discharge) absorbs the spread quickly. Rate shopping pays off on a complex file (non-standard income, atypical property, self-employed applicant) or on a file over CAD 1 million where each basis point matters.

Mechanics: from line draw to Florida closing

The mechanics are simpler than they look. The challenge is in sequencing, not in technical complexity.

Step 1: Canadian prequalification. You ask your main Canadian lender for an increase in the combined line or a refinance, presenting your standard Canadian income file (T1 returns and notices of assessment for the last two years, recent pay stubs if employed, corporate financial statements if self-employed). The lender orders an appraisal on your Canadian property to confirm market value and calibrate the target LTV (65%, 80%, or somewhere in between based on your comfort).

Step 2: B-20 stress test. The lender applies the stress test at the higher of contract rate plus 200 basis points or the published minimum qualifying rate. The total debt service ratio (TDS) must stay below the lender's cap (typically 44% of gross income, sometimes 50% on a strong file). If you fail the test, the increase is denied or reduced. The test covers all your debts, not just the marginal increase.

Step 3: registration and activation. Once underwriting is approved, the lender registers the new mortgage or modification at the Land Registry (Quebec) or the equivalent provincial registry (Land Titles in common-law provinces, Land Registry in Ontario). Legal and registration fees vary between CAD 1,500 and CAD 3,500 depending on province and complexity. The line is typically active 5 to 15 business days after signing.

Step 4: draw and conversion. You draw the amount needed for the Florida closing (down payment plus closing costs, typically 3% to 5% of purchase price, plus a reasonable first-year reserve). You convert CAD to USD. Three realistic FX options: your Canadian lender (typically unfavourable rate, 1.5% to 2.5% spread above interbank), a specialist FX broker such as Knightsbridge FX, OFX or Wise (0.3% to 0.7% spread), or a personal multi-currency account (National Bank International Money Service, RBC U.S. Banking for Canadians). On a USD 500,000 purchase, the spread differential between 0.5% and 2% represents USD 7,500 to USD 10,000. The choice of FX provider therefore deserves as much attention as the choice of lender.

Step 5: wire to Florida closing. The funds in USD are wired from your U.S. account (or from the FX broker's settlement account) to the escrow account of the designated Florida title company at closing. Typical timing: 24 to 48 hours before closing to allow the title company to confirm receipt. Direct wire from Canada almost always triggers extra processing delay and risk of rejection, which is why you should have a U.S. account opened in advance (RBC Bank, BMO Bank N.A., TD Bank N.A., Natbank, Desjardins Bank, or a standard U.S. bank).

Step 6: closing and Florida recording. At closing, you (or your power of attorney) sign the closing documents and the warranty deed that transfers ownership. The title company records the deed with the Florida county records within 5 to 10 business days. You are now sole owner of the Florida property, free of any U.S. mortgage. Your only debt is Canadian, in CAD, secured by your Canadian property.

Canadian tax treatment: deductibility and attribution

Canadian tax treatment of HELOC interest depends entirely on the use of funds, and that is where most mistakes happen.

General rule (paragraph 20(1)(c) of the Income Tax Act): interest on a borrowing is deductible if the borrowing is used to earn income from a business or property. A personal residence does not generate income from property in the tax sense. So if your Florida property is used as a personal second home (snowbird, exclusive family use), the Canadian HELOC interest is not deductible in Canada. That is the default scenario for most Canadian buyers in Florida.

If you rent the Florida property, in whole or in part, the Canadian HELOC interest becomes deductible against rental income (Form T776 on your T1). The traceability rule ("direct use") requires that borrowed funds be directly attributable to the acquisition of an income-producing property. Best practice: open the HELOC, draw the exact amount that funds the rental purchase, wire those funds directly to the escrow account of the title company without transiting through your personal chequing account. Keep documentation end to end. If funds transit through a personal account and mix with other deposits, traceability blurs and the CRA can challenge deductibility.

Mixed-use case: property rented 4 months per year, personal use 8 months. Deductibility is pro-rated based on use. Document the use with a tenant-occupancy calendar versus owner-occupancy. The deductible share equals the rented share of time multiplied by the annual HELOC interest attributable to that property.

Attribution rules. If you draw your HELOC and lend or gift the funds to your spouse who buys the Florida property in their name, the attribution rules (section 74.1 of the Income Tax Act) may attribute the rental income back to you for tax purposes. This structure is rarely advantageous and requires a tax specialist to calibrate correctly.

T1135 filing. A Canadian holding foreign property for exclusively personal use is not required to report it on T1135, regardless of value. A foreign rental property enters T1135 when the total cost of specified foreign property exceeds CAD 100,000 at any time during the year. The Canadian HELOC does not change this obligation: it is the property that triggers the filing, not the financing.

U.S. tax treatment: impact on the property, not the debt

On the U.S. side, the U.S. tax treatment of the Canadian HELOC is essentially neutral for a Canadian without U.S. status, and U.S. taxation attaches to the Florida property itself, not to the Canadian debt.

No U.S. mortgage interest deduction. For mortgage debt to generate deductible interest in the U.S., several conditions must hold simultaneously: the borrower files a U.S. return (1040 or 1040-NR), the debt is secured by a qualified primary or secondary residence per IRC § 163(h), and the taxpayer itemizes deductions. A Canadian non-resident holding a Florida secondary residence paid for in cash via a Canadian HELOC fails the security test: the debt is secured by the Canadian property, not the Florida property. No U.S. deduction is therefore available.

For a rented Florida property, the treatment differs. The Canadian non-resident files a 1040-NR and reports net U.S. rental income. The Canadian HELOC interest is deductible against that rental income if the debt is traceable to the acquisition or improvement of the income-producing property. The U.S. interest-tracing rule (Treasury Regulation § 1.163-8T) is essentially parallel to the Canadian rule. Rigorous documentation is essential: a separate HELOC dedicated to the rental property, direct wire to the Florida escrow without transit, retained statements.

No FBAR or FATCA. The Canadian HELOC is a debt, not a financial account held. No FBAR obligation attaches to a Canadian debt for a Canadian without U.S. status. If the Canadian becomes a "U.S. person" per the IRS (Green Card, Substantial Presence Test, or election), U.S. and Canadian bank accounts of the taxpayer can trigger FBAR above the USD 10,000 threshold, but the HELOC debt itself is not an account for FBAR purposes.

FIRPTA at exit. On resale of the Florida property, FIRPTA applies to the gross sale price (default 15% withholding on a non-resident U.S. seller). This withholding is independent of the financing used to acquire. Whether you paid cash via HELOC, financed via cross-border or via Foreign National, FIRPTA hits at the same rate. The Canadian HELOC will typically be repaid with the sale proceeds after FIRPTA withholding and after seller-side broker commission, documentary stamps and other seller closing costs. See our dedicated FIRPTA guide for the complete withholding mechanics.

CAD/USD currency exposure

This path creates a permanent currency exposure until the HELOC is fully repaid. The debt stays denominated in CAD, but the underlying asset (the Florida property) is in USD. The file's economic balance swings with the exchange rate.

Scenario 1: purchase at a CAD/USD rate of 1.35 (April 2026, level observed in late April 2026 per Bank of Canada). You draw USD 500,000 via Canadian HELOC, equivalent to CAD 675,000 of debt. Over 5 years, the CAD strengthens to 1.25. CAD debt does not change (CAD 675,000), but its USD value is now USD 540,000. The debt feels heavier in USD. Conversely, if the CAD weakens to 1.45, your debt in USD declines to USD 466,000: an implicit FX gain.

Scenario 2: resale of the Florida property 5 years later. You sell for USD 600,000 net (after costs and FIRPTA withholding partially recovered on the 1040-NR). You convert USD to CAD to repay the HELOC. If the rate is 1.25 at sale, you receive CAD 750,000; you repay CAD 675,000 of HELOC, leaving CAD 75,000. If the rate is 1.45, you receive CAD 870,000; CAD 195,000 remains. The final economic outcome depends on the exchange rate at exit, independent of the USD price evolution.

This exposure can be desired (you have a view on CAD) or imposed (you had not thought about the question). Sophisticated buyers partially hedge purchase exposure with a forward contract (rate lock at 30, 60 or 180 days via an FX broker) and accept residual exposure during holding. Hedging holding exposure (rolling forwards) is generally uneconomical for a private individual.

Comparison with cross-border path: a U.S. cross-border loan in USD perfectly matches a USD asset (debt in the same currency as the asset). No currency exposure during holding. FX risk reappears only when principal is paid from CAD income. The Canadian HELOC does the opposite: currency exposure during holding, administrative simplicity at exit.

Economic comparison: Canadian HELOC vs cross-border vs Foreign National

The table below compares the three paths on the essential economic parameters. The HELOC path is labelled Path 4 to align with the numbering on our two pillar articles (Foreign National Loan and Florida foreign national mortgage).

Verified fact. On bank-advertised rates as of May 14, 2026, the typical variable rate on a Canadian HELOC (Canadian prime plus 0.5 to 1 percentage point) sits in the same zone as a 5/1 ARM rate at RBC Bank or TD Bank N.A. cross-border (advertised ARM rate plus 0 to 1 percentage point of foreign-national premium per lender). The gross rate spread between the two paths is typically under 100 basis points. The net economic difference is driven by the closing costs (saved on HELOC path), the foreign-national premium (saved), and the FX exposure (incurred).

Opinion. For an average file with sufficient Canadian equity, the HELOC path beats the Foreign National path on every economic parameter. It beats the cross-border path on fees and premium, but loses on FX exposure. The choice between HELOC and cross-border is therefore largely a currency risk management decision: if you are neutral or positive on CAD over 5 years, HELOC wins; if you want to lock your cost in USD and eliminate FX exposure, cross-border wins.

Full worked example

Case study. Quebec family, Quebec tax residents. Principal residence in Saint-Lambert appraised at CAD 800,000, residual mortgage of CAD 50,000 at Desjardins. Target purchase of a condo in Hollywood, Florida at USD 425,000 as a personal second home (no rental planned). CAD/USD at closing: 1.36.

USD funds needed at closing: purchase price 425,000 plus buyer's closing costs 12,750 (3%) plus inspection and contingency 2,500, total USD 440,250. Conversion at 1.36: CAD 598,740.

Canadian borrowing capacity. 80% combined LTV cap: CAD 640,000. Less residual mortgage CAD 50,000: new available line CAD 590,000. Shortfall of CAD 8,740 to be covered by savings or by marginal HELOC draw. Increase the combined Marge Atout at Desjardins to CAD 640,000, structured as CAD 350,000 amortizing residential mortgage (variable rate at prime minus 0.4, i.e. 5.5% on May 14, 2026), plus CAD 290,000 revolving line (prime plus 0.5, i.e. 6.4%).

At draw, the buyer pulls CAD 600,000 in a single operation: CAD 590,000 for the Florida closing, plus CAD 10,000 cushion. The revolving line drops from CAD 290,000 to zero available on that operation; the amortizing portion is fully used. CAD-to-USD conversion via a specialist FX broker (Knightsbridge FX) at a 0.5% spread on interbank: USD 440,250 received at the title company escrow account.

Annual Canadian cost. Interest on CAD 350,000 amortizing at 5.5%: CAD 19,250/year first year. Interest on the drawn HELOC portion (CAD 250,000 at 6.4%): CAD 16,000/year. Total interest first year: CAD 35,250. Plus principal payment on the amortizing portion (25-year amortization schedule): about CAD 8,600 first year. Total annual Canadian service: CAD 43,850. Origination/legal fees at opening: CAD 2,800.

Saving versus the cross-border alternative. A cross-border RBC Bank or Desjardins Bank loan at 80% LTV on the same condo would have cost approximately: 20% down (USD 85,000, i.e. CAD 115,600 at 1.36) in cash, plus loan USD 340,000 at a 5/1 ARM around 7.5% (illustrative on May 14, 2026). Typical lender fees USD 2,500 (CAD 3,400) plus 1% origination on the loan USD 3,400 (CAD 4,624). U.S. interest year one: USD 25,500 (CAD 34,680 at 1.36). Plus mortgage insurance if applicable (rare at 80% LTV second home), plus Florida documentary stamp and intangible tax (about USD 3,000, i.e. CAD 4,080 at closing).

Year-one balance (excluding FX move):

• Path 4 HELOC: CAD interest 35,250, plus opening fees 2,800. Total year-one cost: CAD 38,050.
• Path 1 cross-border: USD interest 25,500 (= CAD 34,680), plus U.S. lender and closing fees CAD 12,104, plus down payment locked up CAD 115,600 producing no return. Total year-one cash cost (excluding capital locked): CAD 46,784.

Year-one advantage to HELOC: CAD 8,734, before any FX move. This advantage shrinks or reverses depending on CAD/USD movement: a CAD weakening to 1.42 over 5 years lengthens the HELOC debt in USD terms; a strengthening to 1.28 lightens it. On a median scenario of CAD stability between 1.33 and 1.38, the HELOC remains the economically superior option for this file.

Exit 5 years later. Assumed resale price USD 510,000, FIRPTA withholding 15% (USD 76,500 locked until 1040-NR seller filing), seller broker commission 5% (USD 25,500), title and closing seller-side approximately 1.5% (USD 7,650), Florida doc stamps 0.7% (USD 3,570). Net to seller at closing: USD 396,780 cashed directly, plus USD 76,500 of FIRPTA withholding to recover later (typically 6 to 18 months after 1040-NR is finalized). Conversion to CAD at an assumed rate of 1.32: CAD 524,750 cashed immediately.

HELOC repayment: CAD 600,000 initial minus 5 years of capital amortization (about CAD 49,000), leaving a residual balance of CAD 551,000. Shortfall of about CAD 26,250 to be covered by savings or held on the line pending FIRPTA recovery. Recovery of FIRPTA withholding (USD 76,500, i.e. about CAD 101,000 at 1.32) closes the file with a net surplus of about CAD 75,000.

Common mistakes

• Mixing tax traceability. Drawing the HELOC, depositing into a personal chequing account that already holds other funds, and paying the Florida closing from that account. The CRA can challenge the deductibility of interest on the share attributable to the rental property because the tracing chain is broken. Solution: draw the HELOC into a dedicated account and wire directly to the Florida escrow without mixing.
• Forgetting that the stress test runs on the entire file. You raise your combined line and the test covers all your mortgage debt, not just the new tranche. If you already carry a loan on a Canadian rental, the ratio can spike. Run the math before applying, not after the rejection.
• Converting CAD to USD at the Canadian bank counter. The typical spread is 1.5% to 2.5%, i.e. USD 7,500 to USD 12,500 on a USD 500,000 conversion. The same amount through a specialist FX broker costs USD 1,500 to USD 3,500. The FX provider choice has more financial impact than the choice of province where the mortgage is registered.
• Not opening a U.S. account. A direct wire from Canada to the Florida title company triggers an AML review delay of 3 to 10 business days. A wire from a U.S. account (RBC Bank, BMO Bank N.A., TD Bank N.A., Natbank, Desjardins Bank, or a standard U.S. bank) confirms in 24 to 48 hours. Open the U.S. account at least 60 days before closing, deposit a portion of funds in advance to build history.
• Underestimating breakage penalty on a refinance. On a residual mortgage of CAD 200,000 at fixed 5-year rate still 2 years to term, the IRD penalty can reach CAD 8,000 to CAD 15,000. This penalty must enter the arbitrage. Often, increasing the existing combined line rather than refinancing the amortizing loan avoids the penalty.
• Believing the Canadian HELOC entitles you to a U.S. deduction. False. The debt is not secured by the U.S. property, so IRC § 163(h) does not apply for a personal second home. On a U.S. rental property, interest becomes deductible via Treasury Reg § 1.163-8T tracing rules, but only against the net U.S. rental income declared on the 1040-NR.
• Confusing combined LTV and HELOC portion LTV. Wanting 80% in a standalone HELOC is impossible (B-20 caps it at 65%). The 80% requires the combined structure amortizing-plus-HELOC.
• Selling the Canadian property to fund Florida. This strategy triggers a tax event (potential capital gain, end of principal residence exemption if applicable) and removes the principal residence exemption going forward. Often less efficient than keeping the residence and drawing a HELOC.

Step-by-step checklist

1. Confirm that your Canadian property is eligible: principal or secondary residence, in fee simple ownership, no atypical co-ownership (no condo unit with bylaws restricting mortgage charges).
2. Obtain an updated appraisal of your Canadian property, either through your lender or through a licensed appraiser (AACI or CRA in Canada), to calibrate the target LTV.
3. Compile your Canadian income file: T1 returns and notices of assessment for the last two years, recent pay stubs or corporate financial statements for the last three months.
4. Request prequalification from your main Canadian lender. Request a rate quote on variable and fixed for the amortizing portion, and the prime-plus markup on the HELOC portion.
5. Compare with another institution if the advertised delta exceeds 25 basis points on rate or if you perceive service risk.
6. Have the lender run the B-20 stress test and confirm that your TDS remains under cap.
7. Sign the new mortgage or modification, have the mortgage registered at the Land Registry (Quebec) or equivalent provincial registry.
8. Open a U.S. bank account (RBC Bank, BMO Bank N.A., TD Bank N.A., Natbank, Desjardins Bank or a standard U.S. bank) at least 60 days before the projected Florida closing.
9. Choose your FX provider (Canadian bank, specialist broker, multi-currency account) and test with a modest test conversion to validate the process.
10. Draw the HELOC or refinance increment, ideally into a dedicated account rather than a personal chequing account.
11. Convert CAD to USD about 5 to 10 business days before the Florida closing. Deposit USD into your U.S. account.
12. Wire USD from your U.S. account to the Florida title company escrow 24 to 48 hours before closing.
13. Review the Closing Disclosure provided by the title company at least three business days before closing. Verify the amount to bring matches your calculation.
14. Attend closing in person or execute a power of attorney valid under Florida rules. A Canadian notarial act is generally not accepted; use a U.S. consulate or U.S. notary public.
15. Confirm the deed recording at the Florida county within 5 to 10 business days after closing.
16. After closing, keep the full traceability chain (HELOC draw statement, FX order, USD wire, Closing Disclosure, recorded deed) for Canadian and U.S. tax documentation if the property is eventually rented.
17. Check with your Canadian tax specialist whether the acquisition triggers T1135 reporting (yes for rental, no for exclusive personal use). Check application of attribution rules if the debt is carried by a spouse different from the property owner.

FAQ

Can I draw a HELOC on my Canadian principal residence to finance a U.S. purchase?

Yes. OSFI says nothing about destination of funds. You can use the HELOC to buy a vehicle, finance renovations, invest, or buy foreign property. The destination determines the Canadian tax treatment (deductibility), not the legality of the draw.

Does the 80% LTV cap also apply on my Canadian secondary residence?

Yes. The 80% combined B-20 cap applies to residential property, principal or secondary, 1 to 4 units. Properties of 5+ units and commercial properties sit under different rules.

What happens if CAD/USD moves sharply while I hold the property?

Your CAD debt does not change in amount. Its USD value moves inversely to FX. It is an economic exposure, not an additional repayment obligation. You pay your interest in CAD to your Canadian lender regardless of FX. The currency issue materializes at the moment you want to convert the Florida sale proceeds to CAD to repay the HELOC.

Can I get a fixed rate on the HELOC portion?

No, by definition. The HELOC is revolving and variable. You can have a fixed rate on the amortizing portion of a combined product, but the revolving portion is always variable. Some lenders offer rate-cap options or partial conversion to a fixed tranche on a given term (TD Home Equity FlexLine, BMO Homeowner ReadiLine).

Can the Canadian lender freeze my funds after I have drawn them?

Theoretically yes through a "material adverse change" clause in the mortgage documentation, but extremely rare in practice for a file in good standing. The scenario where this happens: major default signal in the file or suspicion of fraud. For a normal file, once the line is registered and the limit confirmed, draws are free up to the limit.

Do I need to notify OSFI or the Bank of Canada about my U.S. purchase?

No. No OSFI filing is required. Your relevant Canadian filings are tax-related (T1135 if foreign rental property above the threshold, regular T1 for eventual rental income) and residual (FINTRAC for wire transfers above CAD 10,000, handled by your bank without action on your part).

Does the HELOC follow me if I sell the Canadian property?

No. The HELOC is secured by the Canadian property. If you sell the Canadian property, the HELOC must be repaid at the Canadian closing, from the sale proceeds. You cannot keep the HELOC without the security property.

Does this path eliminate FIRPTA at resale?

No. FIRPTA applies to the non-resident U.S. seller on resale of U.S. real property, independent of the financing used to acquire. The 15% withholding on gross sale price hits whether you paid cash, financed via cross-border or via Foreign National. For complete mechanics, see our dedicated FIRPTA guide.

Does CMHC insure HELOCs above 80% LTV?

No. CMHC does not insure HELOCs. If you want to go above 80% combined, you must go through an insured amortizing mortgage, and HELOCs remain excluded from insurance. For a buyer financing a second property in Florida, exceeding 80% combined Canadian LTV is not workable via this path in any case.
