HELOC: What is it?
A plain-English guide to Home Equity Lines of Credit in Canada. How it works, who qualifies, what it actually costs, and how to decide if it's the right way to tap your home's value.
Quick answer: A HELOC (Home Equity Line of Credit) is a revolving loan secured by your home. You can borrow up to 65% of your home's value on a standalone HELOC, or up to 80% combined with your mortgage. You only pay interest on what you actually use, and you can re-borrow as you pay it down. The catch: you need income, decent credit, and you have to pass the federal stress test. Variable interest rate — your payment changes when prime rate changes.
What a HELOC actually is
Think of a HELOC as a credit card that's secured against your house. The bank gives you a pre-approved spending limit. You don't pay interest until you actually borrow. When you pay it back, the room becomes available again — that's the "revolving" part.
Two flavours exist in Canada:
- Standalone HELOC: Just the line of credit. Common if you've paid off your mortgage.
- Mortgage + HELOC combo (e.g., Scotia STEP, RBC Homeline): Your mortgage and HELOC sit under one product. As you pay down the mortgage, the HELOC limit grows automatically.
Most Canadian homeowners with a mortgage use the combo product. The standalone version is more common for people in their 60s+ who own their home outright.
How it works
You apply once, get approved for a limit (say, $300,000), and then you can use any portion of it whenever you want.
Most banks give you a few ways to access the money: a special HELOC chequing account, online transfer, a dedicated debit card, or in-branch withdrawal.
You pay interest on the balance you actually owe — not the full limit. If your $300,000 HELOC is sitting at zero, you pay zero interest. Draw $50,000 to renovate? You pay interest on the $50,000.
The minimum monthly payment is usually interest only. You can pay more (and reduce the balance), but the bank only requires the interest. That's why HELOCs can become long-term debt if you're not careful — you can carry the balance forever as long as you pay the interest.
Who qualifies in Canada
- Income: Verifiable through pay stubs, employment letter, or two years of tax returns if self-employed.
- Credit score: Generally 650+. The better your credit, the better your interest rate.
- Stress test: Yes — you have to qualify at the greater of (your contract rate + 2%) or 5.25%. Same federal rule as a mortgage.
- Sufficient equity: You need at least 20% equity in your home AFTER the HELOC is set up. (See the math in the next section.)
- Debt service ratios: Your total monthly housing + debt payments can't exceed 39-44% of your gross income, depending on the lender.
If you don't have steady income — which is the most common reason retirees can't qualify — a HELOC isn't available to you. In that case, the alternatives are a reverse mortgage or selling the home.
How much can you borrow
Two rules, in order:
- HELOC max: 65% of your home's appraised value (standalone).
- Combined max: Your HELOC + any existing mortgage cannot exceed 80% of your home's value.
Whichever is lower wins.
Example (no existing mortgage): Home worth $1,200,000. Max HELOC = 65% × $1,200,000 = $780,000.
Example (with existing mortgage): Home worth $1,200,000, mortgage balance $500,000. Max combined = 80% × $1,200,000 = $960,000. Subtract the $500,000 mortgage → HELOC available = $460,000.
A simple example. Replace the numbers with your own to see your ceiling.
You won't always get the maximum — the bank will assess your income to see how much they're comfortable approving. Just because the math says $460,000 doesn't mean the bank will approve that much.
Interest rates and payments
HELOC rates are variable — they move with the Bank of Canada's prime rate. The HELOC rate is usually quoted as "prime + something", where the something is a small premium the bank adds (typically 0.50% to 1.00%, depending on your bank and your credit).
If prime is 5.45%, your HELOC rate might be 5.95% (prime + 0.50%) or 6.45% (prime + 1.00%).
When the Bank of Canada raises or cuts rates, your HELOC rate moves the same day. Your monthly minimum payment goes up or down accordingly.
Two things that surprise people:
- Payments are interest-only by default. If you borrow $100,000 and never pay it down, you'll still owe $100,000 in ten years. The interest just keeps coming due each month.
- The bank can technically demand repayment. A HELOC is a "demand" loan — most banks don't actually call it, but they have the legal right to ask for the full balance back if your financial situation deteriorates badly.
The trade-offs
Two sides to weigh. Tap either to expand.
Pros
- Way cheaper than credit cards. A HELOC at prime + 0.5% is roughly 6%. Credit cards charge 20%+.
- Flexible. Borrow only what you need, when you need it. No interest on unused room.
- Re-advanceable. Pay it down and the room comes back. Don't have to re-apply.
- Interest can be tax-deductible. If you use the borrowed money for income-producing investments (the "Smith Maneuver"), the interest may be tax-deductible. Talk to an accountant.
- Useful as a safety net. Set it up while you have income and good credit. If something goes wrong later (job loss, emergency), the line is already there.
Cons
- Variable rate risk. If prime rises 2%, your payment rises with it. People who borrowed at 3% in 2021 were paying 6%+ by 2023.
- Easy to over-borrow. Low minimum payments make it feel cheap. Five years later, you're still carrying $50,000 and the principal hasn't moved.
- Your home is collateral. Default = the bank can force a sale.
- Income qualification is strict. If your income drops or you go self-employed, qualifying becomes hard. Set it up while you have stable employment.
- Stress test makes the max lower than you'd expect. The amount you qualify for is calculated at the stress-test rate, not the actual rate. That can shrink the limit meaningfully.
HELOC vs reverse mortgage vs refinance
Three ways to tap your home's equity. Quick comparison:
- HELOC: Lowest interest rate. Requires income. Variable rate. Interest-only payments. Best if you have steady income and want flexibility.
- Refinance (replace your existing mortgage with a bigger one): Lower rate than a HELOC, locked in for a term (e.g., 5 years). Requires income. Full monthly principal + interest payments. Best if you need a large lump sum and want a fixed monthly bill.
- Reverse mortgage: Highest interest rate (1.5% to 3% above mortgage rates). Does NOT require income or credit qualification. No monthly payments at all. Only available 55+. Best as a last resort when income qualification fails.
For most working homeowners under 70, a HELOC or refinance is the better answer than a reverse mortgage.
When a HELOC actually makes sense
I see HELOCs work well in these situations:
- Funding a renovation where you want to draw money in stages as contractors invoice you, not as a single lump sum.
- Consolidating high-interest debt (credit cards, personal loans). Moving from a 22% credit card to a 6% HELOC is a meaningful interest savings — but only if you actually pay it down. Otherwise you've just moved the debt and put your house at risk.
- Building an emergency fund you don't pay interest on until you actually need it. Set up the line while you're employed; hope you never use it.
- Investment leverage (the Smith Maneuver), where borrowed money is invested in income-producing assets and the interest becomes tax-deductible. Higher-complexity, higher-risk strategy. Talk to a fee-only financial planner before doing this.
- Bridging the gap on a second property while you sell the first.
It rarely makes sense if: you're using it to fund lifestyle spending you can't otherwise afford; you're carrying balances on it forever without paying down principal; or you're already stretched on debt service.
