Home Equity Lines of Credit in Canada: Limits, Costs, and Risk

A Home Equity Line of Credit (HELOC) is a revolving credit facility secured against the equity in your primary residence. Canadian lenders are regulated by the Office of the Superintendent of Financial Institutions (OSFI), which caps standalone HELOCs at 65% of the appraised property value. When a HELOC is combined with a residential mortgage on the same property, the total of all secured borrowing cannot exceed 80% loan-to-value (LVR) without CMHC default insurance — and HELOCs themselves cannot be insured.

HELOC rates are variable, tied to each lender’s prime rate (which moves in lockstep with the Bank of Canada’s overnight rate). The typical margin over prime ranges from +0.50% for borrowers with strong credit and a long banking relationship to +1.50% for newer clients or those with lower credit scores. As of mid-2026, with prime sitting at approximately 5.70%, most HELOCs are priced between 6.20% and 7.20%. The minimum monthly payment is interest-only, which is why HELOCs are often dubbed “forever debt” — borrowers can carry six-figure balances for decades without reducing the principal.

To use a HELOC responsibly, treat it as a tool for tactical, short-duration borrowing — bridging the gap between selling and buying a home, funding a renovation that increases property value, or covering an emergency. Avoid drawing from a HELOC to cover regular expenses or to consolidate consumer debt without a strict repayment plan. The interest is tax-deductible in Canada only when the borrowed funds are demonstrably used to earn taxable investment or business income; you must keep meticulous records linking each draw to its income-producing purpose. Lenders can also “reassess” HELOC terms or reduce limits during property value declines or financial stress, so do not treat available credit as a permanent emergency fund.
