Refinancing Your Mortgage in Canada (2026): How It Works, Costs, and When to Do It

Refinancing gets thrown around as a catch-all for "changing your mortgage," but it has a specific meaning — and getting it right can save (or cost) you thousands. Here's exactly how refinancing works in Canada in 2026, what it costs, and when it's worth doing. See refinancing options.

The short answer

Refinancing means replacing your current mortgage with a new one — usually to access equity, lower your rate, or change your terms. In Canada you can refinance up to 80% of your home's appraised value. If you break your existing term to do it, you'll pay a prepayment penalty, so the savings or cash you unlock has to outweigh that cost. The cleanest time to refinance is at renewal, when there's no penalty.

What refinancing actually means

You're not just "getting a better rate" — you're paying out your old mortgage and registering a new one, often for a larger amount. That's different from a straight switch (same balance, new lender) or a port (taking your mortgage to a new home). Refinancing changes the loan amount, the rate, the amortization, or all three.

Why people refinance

• Access equity — take cash out for a renovation, investment, or debt consolidation (how much you can access).
• Consolidate high-interest debt — roll credit cards and loans into your mortgage at a far lower rate (debt consolidation).
• Lower your rate — if rates have dropped enough to beat the break penalty (should you break your mortgage).
• Change your amortization — stretch payments lower, or shorten to pay off faster.

What it costs

The main costs are the prepayment penalty if you break a term early (often the larger of three months' interest or an interest-rate differential — see how penalties are calculated), plus an appraisal (~$300–$500), legal/registration fees, and possibly a discharge fee from your current lender. Run the math first with the refinance calculator.

The step-by-step process

• 1. Define the goal — cash out, lower rate, or restructure. The goal sets the product.
• 2. Check your equity — you need to stay at or under 80% of value after the new loan.
• 3. Qualify — you re-qualify at the stress-tested rate, so income and credit are reassessed.
• 4. Compare the penalty vs. the benefit — this is the decision point.
• 5. Appraisal and approval — the lender confirms value and conditions.
• 6. Legal close — a lawyer or notary registers the new mortgage and pays out the old one.

When refinancing makes sense in 2026

With the Bank of Canada policy rate at 2.25% and prime at 4.45%, rates are stable rather than falling fast — so rate-only refinances mid-term rarely beat the penalty right now. The strongest cases in 2026 are equity access and debt consolidation, where the benefit isn't a rate cut but turning high-interest debt or locked-up equity into usable, low-rate money. If you're near renewal, wait for it. For the bigger picture, see the 2026 outlook.

Frequently asked questions

How much can I refinance my mortgage for in Canada?

Up to 80% of your home's appraised value, across all mortgages on the property combined, minus your current balance.

Does refinancing hurt my credit?

There's a small, temporary dip from the application credit check, but refinancing to consolidate high-interest debt usually improves your credit over time by lowering your utilisation.

Is it better to refinance or wait until renewal?

If you can wait until renewal, you avoid the prepayment penalty entirely — that's almost always cheaper. Refinance mid-term only when the benefit clearly outweighs the penalty. See renewal vs. refinance.

Can I refinance with bad credit?

Often yes — alternative and private lenders refinance based on equity rather than score, though at higher rates. See bad-credit options.
