HELOC vs. Mortgage Refinance in Canada: Which Costs Less When Borrowing $50,000+?

When you want to tap into your home equity for debt consolidation, renovations, or investments, your two main tools are a Home Equity Line of Credit (HELOC) and a mortgage refinance. Here is how to compare their real cost.

Side-by-Side: How a HELOC and a Refinance Differ

Both products are secured against your home's equity, which makes either one significantly cheaper than unsecured credit cards (19.99%+) or personal loans (9% to 14%). However, they work very differently under Canadian lending rules:

Canadian Rules: HELOC vs. Mortgage Refinance

FeatureMortgage RefinanceHome Equity Line of Credit (HELOC)
Maximum Equity LimitUp to 80% of appraised valueUp to 65% standalone (80% combined with a mortgage)
How Funds Are ReceivedOne lump sum at closingRevolving line: draw, repay, and draw again
Interest Rate StructureLower fixed or variable mortgage rateVariable rate (typically Prime + 0.50% to 1.00%)
Monthly Payment RuleScheduled principal + interestOften interest-only minimum on drawn balance
Existing Mortgage ImpactReplaces existing mortgageCan sit behind your existing mortgage untouched

Compare both options with your own numbers in our HELOC Limit & Payment Calculator or our Mortgage Refinance Calculator.

When a Mortgage Refinance Wins

  • You are consolidating a set amount of high-interest debt ($30,000 to $100,000+): Because a mortgage refinance carries a lower interest rate than a HELOC and amortizes over up to 25 or 30 years, it maximizes monthly cash-flow relief while steadily paying down principal.
  • You need between 65% and 80% Loan-to-Value: A standalone revolving HELOC stops at 65% LTV. To access the full 80% equity ceiling, the borrowing above 65% must sit inside an amortizing mortgage.
  • Your mortgage is near renewal: At maturity there is zero prepayment penalty to replace your mortgage and fold in outside balances.

When a HELOC Wins

  • You have an ultra-low fixed rate on your existing mortgage: Adding a standalone HELOC leaves your existing first mortgage and its low rate untouched, avoiding a mid-term prepayment penalty.
  • You are paying for renovations in stages: If a contractor bills you over six months, a HELOC lets you draw as invoices arrive so interest only runs on what has been spent.
