Home Equity Line of Credit (HELOC)

Definition

A Home Equity Line of Credit (HELOC) is a revolving line of credit secured against home equity, usually registered as a collateral charge, that lets a borrower draw funds, repay them, and draw again up to an approved limit without applying for a new loan each time.

How is a HELOC different from a regular mortgage?

A traditional mortgage is amortizing — each payment is a mix of principal and interest that brings the balance to zero by the end of the amortization period. A HELOC is revolving, more like a credit card secured by the home: the borrower can draw funds up to the approved limit, pay them back, and draw again, often paying interest only on the amount actually outstanding.

Because a HELOC is secured, it is typically registered on title as a collateral charge, frequently bundled with an amortizing mortgage segment as a readvanceable mortgage. Borrowers commonly use a HELOC for renovations, debt consolidation, or as a flexible source of funds rather than as the primary financing for a purchase.

How it’s used in Canada

Registered as a collateral charge: most Canadian lenders secure a HELOC with a collateral charge rather than a standard charge, which affects how easily the mortgage can later be switched to another lender.

Often paired with a mortgage: a HELOC is frequently offered alongside an amortizing mortgage as a single readvanceable product from A lenders and credit unions.

Lender-set limits and terms: credit limits, qualifying requirements, and combined loan-to-value rules are set by each lender within the principles-based expectations of OSFI Guideline B-20.

Revolving, not fixed: unlike a lump-sum second mortgage, a HELOC balance can be paid down and redrawn repeatedly without renegotiating the loan.
