Roughly 70% of outstanding Canadian mortgages are expected to come up for renewal by the end of 2026 — a wave largely made up of mortgages originated during the low-rate years of 2020 to 2022. For a lot of those homeowners, renewal means a real payment increase, even with the Bank of Canada’s rate well off its 2023 peak.

The single biggest factor in how painful that renewal is often isn’t the rate environment itself — it’s whether you shopped around or simply signed the renewal letter your existing lender mailed you. Here’s a realistic timeline for doing the former.

Why the renewal letter isn’t your best offer

Your current lender’s renewal letter is a starting point, not a final offer. Lenders count on inertia — most homeowners simply sign and mail it back, because the alternative (shopping, comparing, potentially switching) feels like effort they don’t have room for. That inertia is exactly why the renewal rate you’re first offered is rarely the best rate available to you, from that lender or elsewhere.

This is worth knowing early, because the leverage to negotiate a better rate — with your current lender or a new one — depends entirely on having options lined up before you’re staring down a deadline.

6 months out: Start gathering information, not applications

This is early enough to shop without pressure and late enough that the numbers you’re looking at are actually relevant to your renewal.

Pull your current mortgage details: outstanding balance, current rate, remaining amortization, and your maturity date. Check whether you’re on an insured or uninsured mortgage — this affects your options, including whether you’re exempt from a fresh stress test if you decide to switch lenders (insured mortgages have been exempt from re-testing at switch since 2023; uninsured borrowers doing a straight switch — no increase to loan amount or amortization — gained the same exemption as of November 2024).

Start getting a feel for where current rates sit, both from your existing lender and from the broader market. This is also a good moment to check your credit report for anything that might affect your options, since errors are more common than most people expect and are easier to fix with months of runway than weeks.

4–5 months out: Get real quotes, not estimates

Rate estimates and general market commentary are useful for orientation, but they’re not what you’ll actually be offered. This is the point to talk to a broker or directly compare offers from a few lenders, including your current one.

A broker can typically pull quotes across multiple lenders at once, which matters because rates and incentives vary more between lenders than most people assume — sometimes meaningfully, especially for uninsured borrowers who now have real freedom to switch without a stress-test penalty.

Ask your current lender directly what they can offer if you’re considering leaving. Lenders frequently have more flexibility to improve an offer for an existing client who’s about to walk than they showed in the original renewal letter — but only if you actually ask, ideally with a competing offer in hand.

3–4 months out: Decide fixed, variable, or split — and revisit your amortization

With real offers in front of you, this is the point to make the fixed-vs-variable call for your new term, factoring in your own risk tolerance and how likely you are to break the mortgage again before the next renewal.

It’s also worth checking whether your situation has changed enough to reconsider your amortization. If you’re a first-time buyer, or you’re buying or renewing into a newly built home, 30-year insured amortization has been available since late 2024 — a genuine option for lowering monthly payments if that would meaningfully help your budget, worth understanding even if you ultimately decide against it.

2–3 months out: Lock in your rate

Most lenders let you lock in a rate 90 to 120 days before your renewal date, which protects you if rates move upward before your term actually starts, while typically still allowing you to take a lower rate if one becomes available before closing. Locking in early, once you’re confident in your choice, is one of the lowest-risk moves available in this whole process — there’s rarely a strong reason to wait once you’ve settled on a lender and product.

1 month out: Confirm the paperwork, especially if you’re switching

If you’re switching lenders, this is when the actual transfer happens — new lender pays out the old mortgage, registers against your property, and takes over. Confirm timelines with your broker or new lender well before your maturity date, since a transfer that isn’t completed in time can leave you defaulting to your old lender’s posted renewal rate, which is typically the least competitive rate on offer.

If you’re staying with your current lender, confirm the final negotiated rate in writing and double check it matches what was actually discussed, not the original renewal letter’s number.

The renewal itself

By the time your maturity date arrives, the goal is for this to be uneventful — a rate and structure you chose deliberately, months in advance, rather than one you accepted under deadline pressure because the alternative felt like too much work.

Given how many Canadian homeowners are moving through this exact process at the same time in 2026, lender capacity and appointment availability can also get tighter as more renewals cluster together — one more reason starting the six-month clock early, rather than waiting for the letter to arrive, tends to pay off.
