Should I Switch Mortgage Lenders at Renewal or Stay With My Bank?

Every renewal decision is one of three paths: stay with your current lender, switch at maturity, or break your mortgage mid-term.

Most borrowers deciding at renewal are weighing the first two. Breaking mid-term only makes sense when the rate gap is large enough to absorb the penalty — which is a separate calculation entirely.

The difference in cost between staying passively and staying strategically is often several thousand dollars. That is the gap worth focusing on.

Banks price renewal offers knowing a large percentage of clients will not shop. The initial offer is a starting point that works in the lender's favour, not a reflection of what they are willing to accept.

Long-term clients are frequently offered worse pricing than new clients, not better. Loyalty is not rewarded here. It is counted on.

The only thing that changes the offer is competition. A competing quote from another lender converts the conversation from a formality into a negotiation. Banks have retention teams with real pricing authority. They rarely deploy that authority unless they believe the client might actually leave.

Switching lenders is not the goal. Getting the best outcome is.

There is a pattern that shows up consistently. A borrower shops the market, usually through a broker. They receive a written competing offer. They bring it back to their current bank. The bank then offers a rate they were never going to volunteer on their own.

From the outside, nothing appears to change — the borrower stays with the same lender. From the inside, everything changed. The competing offer created leverage that produced a better rate and potentially a better structure.

If your bank matches or comes close enough, staying is a perfectly reasonable outcome. But without that step, you are negotiating against yourself. The script your current lender's retention team is trained to respond to is covered in detail in how to negotiate your renewal rate.

Not all switches are equally simple. The friction depends on how your mortgage is registered on title — and that choice was usually made at signing, without anyone explaining the trade-off.

Here is where the Big Banks sit in 2026:

• TD — registers most residential mortgages as collateral charges by default, including the TD FlexLine. Leaving TD at renewal is absolutely possible, but the new lender will re-register, and you will typically see $500 to $1,500 in legal and discharge costs unless your new lender runs a full-coverage transfer promotion.
• Scotiabank — the Scotia Total Equity Plan (STEP) is a collateral structure. If your Scotia mortgage sits inside STEP, leaving means discharging the collateral charge, not porting it. Expect $500 to $3,000 once everything is registered again.
• RBC — stand-alone RBC mortgages are registered as standard charges, which transfer cleanly. The RBC Homeline (their combined HELOC product) is collateral — same re-registration cost as TD and Scotia if you are inside that structure.
• BMO — the Homeowner ReadiLine is collateral. A stand-alone BMO mortgage outside ReadiLine can be registered as a standard charge and transferred cleanly.
• CIBC — defaults to standard charges on stand-alone mortgages. Usually a “free switch” scenario where the new lender covers everything except an appraisal (when one is required).
• National Bank — stand-alone mortgages are conventional charges and transfer normally. The All-in-One product is collateral, like the other combined HELOC products on this list.

The honest way to decide is to put real numbers next to the rate gap. A 0.30% improvement sounds the same on a $100,000 balance and a $500,000 balance. It is not. Below are the rough three-year savings from a typical renewal-time rate gap, calculated using Canadian semi-annual compounding on a 25-year amortization.

The $350,000 row is not hypothetical. It matches a real pattern documented on Canadian forums: a borrower at $350,000 moving from 4.08% to 3.74% and seeing around $1,200 a year in savings. Over a three-year term that is roughly $3,600 of real money. Even after a collateral-charge re-registration of $1,000, the borrower keeps more than $2,500.

The $100,000 row is where brokers start telling clients the quiet part out loud: “At this balance, it is probably not worth switching.” $870 in total savings is genuinely small. A single $500 discharge fee cuts it nearly in half. A day off work eats another chunk.

A working framework: balances above $200,000 with a meaningful rate gap — switching frequently wins. Below $150,000 — negotiating with your current lender usually wins. In between, it depends on your charge type, the rate differential, and how much friction the switch involves.

A smooth switch requires starting early. The window is 90 to 120 days before your maturity date.

That window gives you time to shop the market, get written approval from a competing lender, bring the offer back to your current bank, and let their retention team respond with a counter.

When borrowers start three weeks before renewal, the leverage is gone. At that point the easiest option wins by default, and the easiest option is almost always the first offer already sitting in the app. The full 90-day plan is laid out in the 2026 renewal trap guide.

Whether to stay or switch is not actually the right frame. The question that determines the answer is: what structure produces the lowest total cost of borrowing over your next term and beyond?

Rate is one variable. Prepayment flexibility, penalty structure, charge type, and amortization strategy are the others. A slightly higher rate with better terms can cost less overall than the lowest number on the rate sheet.

Most borrowers focus on the rate and ignore the rest. The lenders who benefit most from renewal season are counting on exactly that.

“The lowest rate is what banks advertise to lure you in. The lowest cost of borrowing is what builds your wealth.”— From Debt to Zero

That is the shift. Not rate, not convenience — the strategy to lower your cost of credit.

Spending one to two hours reviewing your options before renewal can completely change your mortgage for the next five years.
