What Is a HELOC?
A HELOC is a revolving credit line secured against the equity in your home. Unlike a mortgage, you borrow what you need, repay it, then borrow again — similar to a credit card but with dramatically lower interest rates and your home as collateral.
The OSFI B-20 Limits
When Is HELOC Interest Tax-Deductible?
The CRA looks at how borrowed money is actually used, not what account it passes through. Mixing HELOC funds in one account destroys deductibility.

HELOC vs Other Borrowing Options
A HELOC is powerful but isn't always the right tool. Here's how it stacks up against other common Canadian borrowing options.
| Option | Typical Rate | Secured? | Best For | Watch Out For |
|---|---|---|---|---|
| ✓ HELOC | 5.45–5.95% | 🏠 Home | Large, ongoing or uncertain expenses; investment borrowing | Home at risk; variable rate; interest-only trap |
| Personal Loan | 7–15% | No | Fixed one-time purchase with known payoff date | Higher rate; no flexibility to re-borrow |
| Mortgage Refinance | 5.0–5.7% | 🏠 Home | Very large lump sum needed at low long-term rate | Penalties for breaking existing mortgage; new qualification |
| Second Mortgage | 8–14% | 🏠 Home | Bad credit; need lump sum; Big 6 won't approve | Very high rate; added default risk |
| Credit Card | 19.99–29.99% | No | Short-term float (pay off monthly) | Catastrophic if carried — never for large expenses |
| Margin Loan | ~7–8% (broker) | Yes (investments) | Leverage within investment account only | Margin call risk; liquidation of portfolio if market drops |
How to Get a HELOC in Canada — Step by Step
Re-Advanceable Mortgages: How They Work
Most of Canada's Big 6 banks offer a combined mortgage + HELOC product — sometimes called a "re-advanceable mortgage." Every dollar of principal you pay on the mortgage automatically unlocks the same dollar in your HELOC, up to the 80% LTV cap.
Major re-advanceable products in Canada: TD FlexLine, RBC Homeline Plan, Scotiabank STEP, CIBC Home Power Plan, BMO Homeowner ReadiLine. These require a separate legal charge at setup (higher upfront cost) but provide automatic credit growth as you pay down the mortgage — valuable for long-term investors.
Frequently Asked Questions
65% of appraised home value for a standalone HELOC. Combined with a mortgage, total borrowing is capped at 80% of home value under OSFI's B-20 guideline.
Only if you use the borrowed funds to earn income — investing in stocks, a rental property, or a business. Personal use (renovations, vacations, debt consolidation) is not deductible. The CRA traces how money is actually used, not just where it goes.
Yes — lenders can freeze, reduce, or cancel a HELOC if your home value drops significantly, your credit score declines, or your income changes materially. Banks typically require 10–30 days notice but are not required to give you time to repay first.
Most Canadian lenders require a minimum credit score of 680. The Big 6 banks typically prefer 720+ for the best rates and limits. Scores below 650 will usually result in denial or a rate spread significantly above prime.
With your existing bank, where they may waive a full appraisal, 5–10 business days is typical. Switching lenders or setting up a re-advanceable mortgage requires a property appraisal and legal work — expect 3–6 weeks.
The Smith Manoeuvre is a Canadian strategy that uses a re-advanceable mortgage to make mortgage interest tax-deductible. As you pay down your mortgage, you immediately borrow the same amount from your HELOC to invest in income-producing assets. The HELOC interest becomes deductible because the borrowed funds earn income. Over decades, this converts non-deductible mortgage debt into deductible investment debt — but it adds significant complexity and risk.
