Home Equity Lines of Credit (HELOC) in Canada

A home equity line of credit, or HELOC, is a revolving credit line secured against your home. In Canada a standalone HELOC is typically capped at 65% of your home's appraised value, while the combined total of all loans secured by the property is usually limited to 80%. You draw what you need, pay interest on the balance, and can reuse the credit as you repay it. Because the line is secured by your home, it usually costs less than unsecured credit, but it also puts your property at risk.

What a home equity line of credit is

A HELOC is not a lump sum. It is a pre-approved borrowing limit you can tap, repay, and tap again, similar to a credit card but secured by real estate. Most lenders register it as a collateral charge on title, which can secure the line and any other borrowing you arrange with the same institution. You might use it for a renovation, to smooth irregular income, or as a standby reserve rather than a planned debt. The flexibility is the feature and the hazard: an unused limit costs nothing, but an available limit invites borrowing.

Some lenders combine a term mortgage with a line of credit in one readvanceable product, so as you pay down the mortgage the available credit grows. That structure is convenient, but it can quietly increase how much you can borrow and how easily you can do it. If you choose it, set your own ceiling below the lender's maximum.

The 65% and 80% limits explained

Two percentages shape how much you can borrow. The first is the standalone HELOC limit, generally 65% of the appraised value of your home. The second is the total secured borrowing ceiling, generally 80% of the appraised value when you combine a mortgage, the HELOC, and any other secured loans. In practice, the room available on your line is the 65% figure minus your existing mortgage balance, subject to the overall 80% cap. These thresholds are set by regulation and lender policy, and they can change, so confirm the current rules with your lender.

Why a HELOC is usually a demand facility

Most HELOCs in Canada are demand facilities, which means the lender can demand repayment or reduce or cancel the limit under the terms of the agreement. In practice this rarely happens to borrowers who stay current, but the power exists. If your home's value falls, your income drops, or the lender decides to tighten its book, the line can be frozen or reduced. That is a meaningful difference from a fixed-term mortgage, which runs for its agreed term. Treat an available limit as something that can disappear, not as a guaranteed reserve.

What a HELOC costs and how repayment works

A HELOC rate is usually variable and expressed as the lender's prime rate plus or minus a margin, so the cost moves when prime moves. Many lenders allow interest-only payments, which keeps the monthly cost low but means the principal never falls on its own. Some borrowers convert part of the balance into a fixed-rate term loan within the same account. There may also be setup or annual fees, and because the charge is collateral, switching lenders later can cost more. Confirm the current margin, prime rate, fees, and repayment terms with your lender before you draw.

Because the rate floats, a small change in prime can meaningfully change your payment on a large balance. Before you rely on a line of credit for a long-term need, test whether you could still afford the payment if rates rose by a few percentage points. That simple check prevents the surprise that catches many borrowers when rates climb.

Risks of moving unsecured debt onto your home

The most common and most dangerous use of a HELOC is consolidating credit card or other unsecured debt. The interest rate falls, but the debt changes character: it becomes secured by your home. If you default, the lender can pursue the property, not just your credit rating. Consolidation also tends to fail when the borrowing behaviour does not change, because the freed-up cards get used again and the total debt grows. A HELOC can be a useful tool, but it is not a fix for a budget that does not balance. The debt consolidation guide sets out the risks in detail.

HELOC versus a refinance, a loan, or a second mortgage

A HELOC suits ongoing, flexible needs where the amount and timing vary. A refinance suits a one-time lump sum and a fixed repayment plan. A home equity loan provides a fixed amount at a fixed rate, and a second mortgage sits behind your first mortgage and usually costs more. If you need a defined amount for a defined purpose, a fixed product may keep you disciplined; if you need a standby line, a HELOC fits better. Compare the structures in home equity loan versus HELOC and see how a refinance works in accessing home equity through a refinance.

How to use a HELOC responsibly

• Borrow for a defined purpose and a defined repayment period, not as a permanent income supplement.
• Pay more than interest so the balance actually falls.
• Keep the limit below what you could comfortably repay if rates rose.
• Do not consolidate unsecured debt unless you have changed the spending that created it.
• Check whether the charge is collateral before you sign, because it affects future switching.
