Canada Mortgage Transfer Guide: Switching Lenders at Renewal

These terms are often confused: Mortgage transfer (switch): Moving your existing mortgage — same balance, same remaining amortization — to a new lender at renewal or any time (with penalty mid-term). Purpose: get a better rate. No new money borrowed; amortization continues as-is. Refinance: Changing the mortgage structure — increasing the balance (to access equity), changing the amortization period, or adding features like a HELOC component. Requires full underwriting. Maximum 80% LTV (cannot access last 20% of equity). Renewal: Staying with the same lender for a new term at a negotiated rate. Port: Transferring your mortgage to a new property (when you sell and buy simultaneously). Key point: at maturity (end of your term), a transfer to a new lender is typically penalty-free and does not require a full refinance. Mid-term transfers trigger a payout penalty. See mortgage renewal glossary and OSFI B-20 residential mortgage guidelines.

Savings depend on the rate differential and remaining amortization. Example: $450,000 mortgage balance, 20 years remaining amortization, renewing for 5 years. Current lender renewal offer: 5.50%. New lender offer: 5.10%. Rate difference: 0.40%. Monthly payment difference at 0.40%: approximately $103/month. Over 5-year term: ~$6,180 in interest savings. Against fees: some lenders cover legal fees for a straight transfer ($800–$1,500 value). Net savings: $4,500–$5,500 after fees. With a mortgage broker: brokers often find rates 0.25–0.50% below posted bank rates, and many arrange for the new lender to cover transfer legal costs. Don't accept the first renewal offer — it is almost always a starting point, not the best available. See refinancing vs. renewal guide and the FCAC mortgage renewal guide.

Canada's mortgage stress test (OSFI B-20) requires borrowers to qualify at the greater of their contract rate + 2%, or 5.25% (as of 2025), regardless of the actual mortgage rate. Does the stress test apply to a straight transfer? As of 2023 and amended guidance: for an uninsured mortgage transferred at the same balance and amortization to a federally regulated lender (bank), the stress test may not apply for a "straight switch" — specifically OSFI's 2022 amendment created an exemption for portfolio transfers at equivalent terms. However, this exemption applies to federally regulated lenders, not all lenders. Credit unions and provincially regulated lenders may apply different rules. Key caveat: If you are increasing the balance (refinancing), changing the amortization, or switching from an insured to uninsured mortgage, the full stress test applies. Confirm with your new lender before proceeding. See Canada mortgage stress test glossary and OSFI B-20 guideline.

Two penalty types apply depending on mortgage type: Variable-rate mortgage: Penalty = 3 months' interest on the outstanding balance. Example: $450,000 balance × 5.75% rate ÷ 12 months × 3 = $6,469 penalty. Straightforward and relatively predictable. Fixed-rate mortgage: Penalty = greater of: (1) 3 months' interest, OR (2) Interest Rate Differential (IRD). IRD = (Contract rate − Posted rate for remaining term) × balance × remaining months/12. The IRD can be extremely large when rates have fallen since your mortgage was taken out — borrowers have seen penalties of $20,000–$50,000+ on mid-term fixed breaks. Banks use their own posted rate methodology for IRD, which is not standardized. Monoline lenders (First National, MCAP) often use discounted comparison rates — smaller IRD penalties. Compare lender penalty calculations before committing to a fixed rate. See prepayment penalty glossary and the FCAC prepayment penalty guide.

Both paths can work — here is how to decide: Use a mortgage broker when: You want to compare multiple lenders at once without multiple credit inquiries (brokers do a single pull and submit to multiple lenders); you want access to monoline lenders (First National, MCAP, RMG) that do not have a retail presence; you want negotiating expertise and knowledge of which lenders are most competitive right now; you have a complex situation (self-employed, non-standard property). Go directly to a lender when: You already have a strong relationship with a lender and they are offering competitive rates; you prefer one-on-one service at a branch. Broker cost: Mortgage brokers are paid a finder's fee by the lender — no direct cost to borrowers in most cases. Independent brokers are also bound by FSRA (Ontario) or provincial regulator to act in your interest. See how to use a mortgage broker in Canada and FCAC — Shopping for a mortgage.

If your mortgage is insured (you had less than 20% down when you purchased), the CMHC insurance follows the mortgage: (1) Transfer at renewal: CMHC insurance transfers to the new lender — you do not pay the premium again; (2) Insurance portability: CMHC, Sagen, and Canada Guaranty all have portability provisions — insurance remains in place as long as the loan-to-value remains within original insured parameters; (3) Premium already paid: Your CMHC premium was added to the mortgage balance when you originally bought — you do not pay a new premium simply because you switch lenders; (4) Exception: If you are refinancing and increasing the balance beyond the original insured amount, additional premium may apply. Confirm with the new lender that they are aware the mortgage is insured — it affects their risk and pricing. Insured mortgages often attract lower rates than uninsured mortgages because the lender's credit risk is backstopped by CMHC. See CMHC insurance glossary and CMHC mortgage insurance overview.
