Canada HELOC guide 2027: readvanceable mortgages, stand-alone HELOCs, and how to qualify
A Home Equity Line of Credit (HELOC) in Canada lets homeowners access up to 65% of their home's value as a revolving credit line at prime-based rates. The most common Canadian product is the readvanceable mortgage — a combination of an amortizing mortgage and a HELOC that grows as the mortgage is paid down. This guide explains HELOC qualification, rate structures, the OSFI 65% LTV cap, and the Smith Manoeuvre.
A HELOC at prime + 0.50% is dramatically cheaper than a personal loan, a fixed second mortgage, or a reverse mortgage. But Canada's readvanceable structure also creates lock-in risk, and the 65% LTV cap limits access more than most borrowers expect. Here's how to use it strategically.
HELOC structures in Canada: stand-alone vs readvanceable
| Feature | Stand-alone HELOC | Readvanceable mortgage |
|---|---|---|
| Structure | Revolving credit line only | Amortizing mortgage + HELOC combined |
| Limit growth | Fixed at approval | Grows automatically as mortgage is paid down |
| Lender flexibility | Easier to transfer to another lender | Often requires full refinance to switch lenders |
| Smith Manoeuvre compatible | Yes — with manual tracking | Yes — built-in (preferred structure) |
| Common providers | Credit unions, some banks | Major chartered banks (CIBC, RBC, Scotia, TD, BMO) |
| Repayment flexibility | Interest-only typical; full repayment anytime | Mortgage payments fixed; HELOC open |
Step-by-step: accessing a HELOC in Canada
- 1Verify you have sufficient equity (minimum 20% required)
To access a HELOC in Canada, your combined mortgage + HELOC cannot exceed 80% of your home's appraised value (65% for the HELOC portion alone, per OSFI regulations). This means you must have at least 20% equity before a HELOC is accessible. If you bought with 5% down and your home hasn't appreciated significantly, you likely don't qualify yet. Check your estimated home value vs your outstanding mortgage balance to confirm you have the required equity cushion.
- 2Understand the two main HELOC structures in Canada
In Canada, HELOCs come in two main forms: (1) <strong>Stand-alone HELOC</strong> — a revolving credit line secured against your home, separate from your mortgage, up to 65% LTV. Interest-only payments are typical. (2) <strong>Readvanceable mortgage</strong> (e.g., Scotia Total Equity Plan, CIBC Home Power Plan, RBC Homeline Plan) — combines an amortizing mortgage with a HELOC component. As your mortgage is paid down, the HELOC limit automatically increases. This is the most common structure at major Canadian banks. The key advantage of readvanceable: you never need to reapply to access re-paid principal.
- 3Get your home appraised and apply for the HELOC
Lenders will order an appraisal (at your expense, typically $300–500) to confirm the home's current market value. The HELOC limit is calculated as: (home value × 80%) − outstanding mortgage balance, up to the 65% cap on the HELOC portion. Income and credit qualification are similar to a mortgage: TDS ratio must remain within limits when HELOC interest is added, and most lenders require a credit score of 650+. Variable-rate HELOCs are stress-tested at the higher of the contract rate + 2% or the Bank of Canada benchmark rate.
- 4Compare rates and lenders
Canadian HELOC rates are almost universally variable, set at prime rate + or − a spread. In 2027, most major bank HELOCs are priced at prime + 0.50% to prime + 1.00%. Some credit unions and alternative lenders offer prime − 0.10% to prime + 0.25% for strong-profile borrowers. Monoline lenders (who typically offer competitive mortgage rates) do not offer HELOCs as of 2027 — so HELOCs are typically obtained from schedule A banks or credit unions. Fixed-rate HELOC sub-accounts are available at some lenders (e.g., converting a HELOC balance to a fixed-term mortgage segment).
- 5Draw and repay strategically
A HELOC is revolving credit — you can draw, repay, and draw again up to the limit during the draw period. Interest is charged only on the outstanding balance, not the full limit. Most Canadian HELOCs are open, allowing full repayment at any time without penalty. Strategy: use the HELOC as a short-term facility for renovation projects or investment purchases, then repay aggressively to minimize interest. Avoid treating a HELOC as permanent debt — the prime-rate variable nature means payments rise immediately when the Bank of Canada raises rates.

- 6Understand the Smith Manoeuvre (optional advanced strategy)
The Smith Manoeuvre is a Canadian tax strategy that converts non-deductible mortgage interest into tax-deductible investment loan interest. Using a readvanceable mortgage: as you make mortgage payments, the HELOC limit increases; you borrow from the HELOC to invest in eligible income-producing investments; the HELOC interest becomes tax-deductible against investment income. This effectively transforms your mortgage into a tax-deductible loan over time. The strategy requires careful execution and a qualified financial advisor — the CRA monitors aggressive tax planning.

Common questions
What is the maximum HELOC amount in Canada?
Under OSFI Guideline B-20, Canadian federally regulated lenders are capped at 65% LTV for the HELOC portion alone. When combined with a mortgage, the total (mortgage + HELOC) cannot exceed 80% of the home's appraised value. Example: $800,000 home with a $500,000 mortgage — the maximum HELOC is the lesser of: (65% × $800,000) = $520,000, or (80% × $800,000) − $500,000 = $140,000. The binding constraint is $140,000. A home with no mortgage could theoretically access 65% × $800,000 = $520,000. The 65% cap applies to all federally regulated lenders — credit unions (provincially regulated) may have different caps. See OSFI Guideline B-20.
What is the current HELOC interest rate in Canada (2027)?
Canadian HELOCs are priced at prime rate ± a spread. In late 2026 through 2027, the Bank of Canada overnight rate has declined to approximately 3.25–3.75% following the 2024–2025 easing cycle, putting the chartered bank prime rate at approximately 5.45–5.95%. At prime + 0.50%, HELOC rates are approximately 5.95–6.45%. This is significantly below the 7–8% fixed mortgage rates seen in 2023–2024. The variable nature of the HELOC rate means borrowers benefit immediately when the BoC cuts rates, but face immediate payment increases when rates rise. Monitor the Bank of Canada's rate decisions at Bank of Canada key interest rate page.
What is a readvanceable mortgage in Canada?
A readvanceable mortgage is a combined product offered by major Canadian banks that links an amortizing mortgage with a HELOC in a single facility. As you make mortgage payments and pay down principal, the HELOC limit automatically increases by the same amount — so the total available credit (mortgage balance + HELOC limit) remains constant at the original approved amount. You can reborrow the repaid principal at any time through the HELOC without reapplying. Major products: Scotiabank's STEP (Scotia Total Equity Plan), CIBC's Home Power Plan, RBC's Homeline Plan, TD's Home Equity FlexLine. These products lock borrowers into their bank long-term — switching lenders often requires a full refinance and discharge of the readvanceable structure. FCAC HELOC guide.
Can I deduct HELOC interest in Canada?
HELOC interest is deductible in Canada only if the borrowed funds are used for income-producing purposes — investing in a business, purchasing eligible investments, or funding a rental property. Personal HELOC use (home renovation, vacation, car purchase, paying off credit cards) is not deductible. The CRA requires you to track the purpose of each draw — if you mix personal and investment use in the same HELOC, you must track and allocate interest accordingly. The Smith Manoeuvre (described in the guide above) is a strategy to systematically convert personal mortgage debt into deductible investment debt. Get professional tax advice before implementing any interest deduction strategy. Full CRA guidance at CRA carrying charges and interest expenses.
What credit score is needed for a HELOC in Canada?
Most major Canadian banks require a credit score of at least 650 for HELOC approval, with 680+ typically needed for the best rates and highest limits. Credit unions may be more flexible. Qualification also requires: (1) sufficient verified equity (20%+ in the home); (2) TDS ratio within limits when HELOC minimum payments are included — typically maximum TDS of 44% under stress test; (3) stable income documented with 2 years of NOAs (Notices of Assessment) for self-employed borrowers, or T4s and pay stubs for employed; (4) no recent major credit derogatory items (bankruptcy, consumer proposal). HELOC applications are stress-tested at the higher of the contract rate + 2% or the Bank of Canada 5-year benchmark rate. See OSFI B-20 for stress test rules.
What happens to my HELOC if home values decline?
If your home's value declines and the combined mortgage + HELOC balance exceeds 80% of the new value, your lender has the right to reduce your HELOC limit (called "freezing" or "reducing" the line). This means you could lose access to undrawn HELOC funds — even if you have an excellent payment history. During the 2022–2023 correction in some Canadian markets, several lenders reduced HELOC limits on properties that had declined in value. If you have an outstanding HELOC balance, the lender cannot demand immediate repayment — but they can stop new draws. This is a key risk of relying on a HELOC for emergency liquidity: your access to the funds can be cut when you need them most (during a market downturn that also likely coincides with financial stress). Keep a separate emergency fund that doesn't depend on home equity. The FCAC HELOC guide covers this risk explicitly.
