A HELOC (Home Equity Line of Credit) lets you borrow against the equity in your home at a much lower interest rate than a personal line of credit or credit card. It’s one of the cheapest forms of borrowing available to Canadian homeowners — and one of the most dangerous if you use it wrong.
How a HELOC works
A HELOC is a revolving line of credit secured by your home. The bank gives you a credit limit based on your equity, and you can draw on it whenever you want, up to the limit. You pay interest only on what you’ve actually borrowed.
Example: Your home is worth $800K. Mortgage balance is $400K. You have $400K of equity. The bank lets you borrow up to 65% of home value MINUS existing mortgage:
65% × $800K = $520K maximum total secured debt — Minus $400K mortgage = $120K HELOC limit.
Current HELOC rates (May 2026)
- Standalone HELOC: Prime + 0.5% to 1.0%. With BoC prime at 5.20% in 2026, that’s 5.70-6.20%.
- Readvanceable mortgage HELOC (combined with your mortgage): Prime + 0.0-0.5%, so 5.20-5.70%.
- Compare to alternatives: Personal line of credit ~9-12%. Credit cards ~20%. Cheapest non-mortgage borrowing in Canada by a wide margin.
Standalone HELOC vs Readvanceable Mortgage
- Standalone HELOC: Separate from your mortgage. Apply, get approved, draw when needed. Most banks offer them.
- Readvanceable Mortgage (HELOC built-in): Combo product where every dollar of mortgage principal you pay down ADDS to your HELOC limit. Available at: National Bank All-In-One, RBC Homeline, Scotia STEP, TD HELOC + mortgage combo, Manulife One. Powerful for paying down debt or implementing the Smith Manoeuvre.
When a HELOC actually makes sense
- Home renovations. Cheaper than reno loans or putting it on credit cards. Interest may be tax-deductible if the reno is for an income-producing portion of your home (rental basement, home office).
- Emergency fund backup. Free to have ($0/month if you don’t use it). When the furnace dies in January, you have $50K available immediately at 6% instead of $15K on a credit card at 20%.
- Bridge financing for a home purchase. Sold your old place, closing on new place 30 days later — HELOC covers the gap cheaper than a bridge loan.
- Smith Manoeuvre (tax-deductible-interest strategy). Borrow from HELOC to invest in dividend-paying stocks; interest becomes tax-deductible (consult an accountant first).
- Debt consolidation if you have $20K+ of high-interest credit card debt and you’ll commit to paying off the HELOC quickly. NOT a way to just shuffle debt around forever.
When NOT to use a HELOC
- To fund lifestyle spending. Vacations, cars, weddings — financing depreciating things with your house’s equity is a fast path to crisis when rates rise or property values fall.
- To “invest” in speculative assets. Crypto, options trading, individual stock picks. If the bet loses, you’ve lost equity in your house.
- If you can’t reliably pay it down. Banks can demand repayment of the entire HELOC balance if your financial situation deteriorates. They’ve done this in past recessions.
Qualifying for a HELOC
- 20%+ equity in your home (so total secured debt stays under 80% of value).
- Stress test: Yes, HELOCs require qualifying at the contract rate + 2% or 5.25%, whichever is higher (same as mortgages).
- Good credit: 680+ score typical; 720+ for the best rates.
- Debt service ratios: GDS under 39%, TDS under 44%.
HELOC repayment terms
Unlike a mortgage, most HELOCs are interest-only minimum payments. On a $100K balance at 6%, your minimum payment is just $500/month — but you’d never pay down principal. Pay more than minimum to avoid carrying balance for life.
Frequently asked questions
Can the bank actually cancel my HELOC or demand full repayment?
Yes, and this surprises people. HELOCs are “demand” facilities in Canada — the lender can reduce your limit, freeze further draws, or call the entire balance due if your financial situation changes, your home value drops significantly, or broader credit conditions tighten. It’s rare but it happened to some homeowners during 2008-2009 and again in pockets during 2020.
The practical takeaway: don’t treat HELOC room as guaranteed long-term capital. If you’re using it for the Smith Manoeuvre or as your emergency fund, have a Plan B (a real cash buffer, a margin account, or a personal LOC) in case the tap gets turned off.
Does opening a HELOC hurt my credit score?
The application triggers a hard credit pull, which dings your score by a few points temporarily. Once open, the HELOC reports as revolving credit — so a $120K limit sitting unused actually helps your utilization ratio. Drawing $90K against that $120K limit, on the other hand, looks like 75% utilization and will pull your score down meaningfully.
How is a HELOC different from refinancing my mortgage to pull out equity?
A refinance breaks (or replaces) your existing mortgage and gives you a lump sum at a fixed or variable mortgage rate — typically lower than HELOC rates, but you pay interest on the full amount from day one and may face a prepayment penalty on the old mortgage. A HELOC sits on top of your existing mortgage, costs nothing if unused, and charges interest only on what you draw, but at Prime + 0.5-1.0% it’s a higher rate than a 5-year fixed mortgage in 2026.
Rule of thumb: refinance if you need a known lump sum for a specific purpose; HELOC if you need flexible access over time.
Is HELOC interest tax-deductible in Canada?
Only when the borrowed money is used to earn income — buying dividend stocks, funding a rental property, or financing a legitimate business expense. Interest on a HELOC used for a kitchen reno or a vacation is not deductible. When my mom asked me about this last year — she’d heard from a neighbour that “HELOC interest is a write-off” — I had to explain the CRA cares about the use of funds, not the loan product. Keep clean records tying each draw to its purpose, because if CRA audits, you’ll need to trace the money.
Should I get a standalone HELOC or a readvanceable mortgage?
A readvanceable mortgage (Scotia STEP, RBC Homeline, National Bank All-In-One) is more powerful if you actively want your borrowing capacity to grow as you pay down the mortgage — useful for the Smith Manoeuvre or staged renovations. A standalone HELOC is simpler, easier to switch lenders at renewal, and keeps your mortgage and credit line cleanly separated. For most homeowners who just want emergency backup, the standalone version is enough.
