Mortgage Renewal in Canada: The Costly Mistake Most Homeowners Make (And How to Avoid It)

Your mortgage term is coming to an end. Your bank sends you a renewal letter. You sign it and send it back. Done, right?

Wrong — and that decision could cost you thousands of dollars.

Mortgage renewal season is one of the most financially significant moments in any Canadian homeowner’s life, and it’s also one of the most mishandled. The majority of Canadians simply accept whatever rate their existing lender offers at renewal without questioning it, comparing it, or negotiating. According to mortgage industry data, fewer than 30% of Canadian homeowners actively shop for a better rate at renewal time.

That’s a costly habit to have. Here’s what you should actually do — and when.

Why Your Bank’s Renewal Offer Is Almost Never Their Best Rate

When your lender sends you a renewal offer, there’s something important to understand: that initial offer is not their best rate. It is their hoped-for rate — the number they’d like you to accept without looking around. Banks know that renewal time is high-friction for most borrowers. Switching lenders involves paperwork. Most people assume it’s complicated. And so, many homeowners simply sign the first number they see.

This is exactly what banks count on. The difference between accepting a bank’s posted renewal rate and negotiating (or switching) to a competitive market rate can easily be 0.5% to 1.0% or more — and on a $400,000 mortgage balance, that’s $2,000 to $4,000 per year in unnecessary interest charges.

The good news: you have enormous leverage at renewal time, because your mortgage balance is uninsured, already existing, and moving your business to a new lender requires minimal paperwork compared to what you did at the original purchase.

The 120-Day Window: Your Most Important Timeline

The single most important thing Canadians can do differently at renewal time is start the process early. Here’s why: most Canadian mortgage lenders allow you to lock in a new rate up to 120 days (about 4 months) before your maturity date, with no obligation and no cost.

This means that if your mortgage renews on October 1st, you can secure a rate from a new lender as early as June 1st. If rates rise between June and October, you’re protected. If rates drop further, many lenders will allow you to take the lower rate at maturity. It’s a one-way bet — and most Canadians don’t take it.

Here’s a renewal timeline to follow:

• 120 days out: Begin reaching out to a mortgage broker to review the market. Get a rate hold from at least one competitive lender.
• 90 days out: Request your existing lender’s best renewal offer in writing. Compare it against what’s available in the market.
• 60 days out: Decide whether to renew with your existing lender or switch. If switching, your broker will begin the transfer paperwork.
• 30 days out: Finalize your new rate, term, and lender. No payment interruptions — the new lender coordinates directly with your existing lender.
• Renewal date: New mortgage takes effect seamlessly. You save thousands.

How Much Can You Actually Save by Shopping Your Renewal?

Let’s make this concrete. Suppose you have a remaining mortgage balance of $350,000 and you’re coming up for renewal with your bank offering you a 5-year fixed at 5.25%. A competitive market rate for the same product through a mortgage broker might be 4.69%.

The difference in monthly payment: roughly $130/month. Over a 5-year term: roughly $7,800 in additional interest paid to your bank versus the competitive rate.

For doing nothing more than a few phone calls and signing some paperwork at renewal, that’s an extraordinary return on time invested.

When It Makes Sense to Stay With Your Current Lender

To be fair — sometimes renewing with your existing lender is the right call. This is typically the case when:

• Your current lender matches the market rate after negotiation (always try to negotiate before accepting)
• You have a portable mortgage and are planning to move during the term
• You value the convenience of your existing banking relationship and the rate difference is minimal (under 0.15%)
• You have a complex mortgage structure, such as a combination mortgage with HELOC, that would be time-consuming to transfer

Even in these cases, having a broker comparison in hand gives you negotiating leverage. Your lender knows you’ve shopped around — and the renewal offer you get next will be better for it.

What About Breaking Your Mortgage Before Renewal?

If your renewal date is still several years away but current market rates are significantly lower than what you’re paying, it might be worth calculating the cost of breaking your mortgage early.

Breaking a fixed-rate mortgage triggers a prepayment penalty — typically the greater of three months’ interest or an Interest Rate Differential (IRD) calculation. IRD penalties can run from a few thousand to over $20,000 depending on your lender, your original rate, and how far you are from maturity.

The question is whether the interest savings over the remaining term (plus your new term) outweigh the penalty. This is a calculation a mortgage broker can run for you in minutes — and the answer sometimes surprises people.

Working With a Mortgage Broker at Renewal: What You’re Missing

If you’ve always renewed directly with your bank, you may not know that working with a mortgage broker at renewal costs you nothing. Brokers are compensated by lenders, not by borrowers. And at renewal time, they provide something invaluable: a real-time market scan of dozens of lenders’ best rates, compared side-by-side with your existing offer, in a matter of hours.
