Understanding HELOC: Home Equity Line of Credit Explained

October 15, 2025 •

What Is a HELOC?

As you pay down your mortgage and your home appreciates in value, you build up equity. That equity represents real wealth, but it’s locked up in your property. A Home Equity Line of Credit, or HELOC, is one way to access that equity while continuing to own your home.

A HELOC is a revolving line of credit secured against your home. You can borrow up to a certain limit, repay it, and borrow again, similar to a credit card but with much lower interest rates.

How HELOCs Work

The Credit Limit

Your HELOC limit is based on your home’s value and your existing mortgage. In Canada, you can borrow up to 65% of your home’s value through a HELOC, but the combined total of your HELOC and any mortgage cannot exceed 80% of the value.

Interest Rates

HELOC rates are variable and tied to the lender’s prime rate. You might see a HELOC quoted as “prime + 0.5%” or similar. Only the amount you actually borrow accrues interest.

Repayment

Unlike a mortgage, HELOCs typically require only interest payments each month. There’s no required principal repayment, though you can pay down the balance whenever you want.

Common Uses for a HELOC

  • Home renovations: Particularly for projects that increase your home’s value
  • Investment purposes: The interest may be tax-deductible if used for investments
  • Education expenses: Funding post-secondary education
  • Emergency fund: Having access to funds for unexpected expenses
  • Debt consolidation: Paying off higher-interest debts

HELOC vs. Refinancing: Which Is Better?

Choose a HELOC if: You want ongoing access to funds, you’re not sure how much you’ll need, or you want to minimize upfront costs.

Choose refinancing if: You need a large lump sum, you want to lock in a fixed rate, or you want to restructure your entire mortgage.

The Risks of HELOCs

Variable Rate Exposure

HELOC rates fluctuate with prime. If rates rise significantly, your interest costs increase.

Easy Access to Debt

The convenience of a HELOC can be a double-edged sword. It’s easy to borrow more than you should.

Secured Against Your Home

If you can’t repay, you’re putting your home at risk.
