Mortgage Renewal in Toronto: Should You Switch Lenders or Stay?

Somewhere between three and four months before your mortgage term ends, a renewal letter shows up from your current lender with a new rate and a form to sign. Most people sign it. Most people probably shouldn't — at least not without checking what else is out there first.

Here's why, and how to actually approach it.

Why the renewal letter isn't automatically your best deal

Your existing lender already has your business. Statistically, most homeowners renew with the same lender without shopping around — which means lenders have limited incentive to offer their sharpest rate on renewal. Their retention rate and their best rate for new customers are frequently two different numbers.

That's not a conspiracy, it's just how the incentives work. It also means the burden is on you to check whether the letter you received actually reflects the market, or just reflects what your current lender is comfortable offering someone they assume won't shop around.

What renewing with a new lender actually involves

Switching lenders at renewal is far less involved than most people expect — it is not the same process as your original mortgage application:

No need to requalify under a brand-new purchase scenario in most switch cases
Standard documents: income verification, current mortgage statement, property details
The new lender typically covers standard legal and administrative costs for a straightforward switch
Timeline is usually a few weeks, well within the renewal window if you start early

Because it's a "switch," not a full new approval process, much of the friction people expect simply isn't there.

When it makes sense to switch

Your current lender's renewal rate is meaningfully higher than what's available elsewhere for a comparable term
Your financial situation has improved since your last mortgage (higher income, better credit, more equity) and you're not getting credit for it
You want to change your amortization, payment frequency, or take advantage of features (prepayment privileges, portability) your current product doesn't offer
You're planning to access equity anyway — a switch can sometimes be combined with a refinance

When staying put makes sense

Your current lender's renewal offer is already competitive when actually compared against the market
You have a specialized product (certain self-employed or alternative lending arrangements) where switching could mean requalifying under stricter standard criteria
The savings from switching don't outweigh the (usually modest) hassle for your specific situation

The point isn't "always switch." It's "always check" — the two scenarios above only make sense to distinguish between if you've actually compared.

The timeline that matters

Start looking 90–120 days before your renewal date. Most mortgage rates can be held for a set period, meaning you can lock in a rate months ahead of your actual renewal date, then still take advantage of a rate drop if one happens before closing, depending on the lender's policy. Waiting until the renewal letter arrives with a few weeks left doesn't leave much room to properly compare offers.

What this actually looks like in practice

I'll shop your renewal across the lenders I work with, compare that against what your current lender is offering, and tell you honestly which is better — including when the answer is "stay where you are." There's no benefit to me steering you toward a switch that doesn't actually save you anything.

If your renewal is coming up, the rate comparison tool is a quick way to see roughly what a rate difference is actually worth over your term, and from there we can look at real numbers for your file.
