Mortgage Renewal in Canada: What Happens to Your Payment
A mortgage renewal in Canada arrives with a piece of paper and a deadline, and most of the money is decided before either shows up. Federally regulated lenders have to send you a renewal statement at least 21 days before your current term ends. That statement tells you the balance, the rate on offer, the payment, the term and any fees. What it does not tell you is that the rate printed on it is an opening offer.
Here is what actually gets decided at renewal, worked through with real arithmetic on a specific example, plus the three levers you have and what each one costs.
What the renewal statement has to contain
The Financial Consumer Agency of Canada sets out the rules for federally regulated lenders such as banks on its renewing your mortgage page (page dated October 15, 2025). The lender must give you a renewal statement at least 21 days before the end of your existing term, and it must include:
- the balance, or remaining principal, at the renewal date
- the interest rate
- the payment frequency
- the term
- any charges or fees
The statement also has to specify that the rate being offered will not increase before your renewal date. And if the lender will not be renewing your mortgage, it has to tell you that 21 days before the term ends too.
The part worth circling: if you do nothing, your renewal may be automatic, and FCAC is blunt that you may not get the best rate that way. Where a lender plans to renew automatically, the statement has to say so. An automatic renewal is a decision. It is just a decision made by default.
You will face this more than once. Unless you pay the balance in full at the end of a term, you have to renew, and a mortgage usually takes several terms to fully repay. FCAC’s advice is to start shopping a few months before your term ends rather than waiting for the renewal letter to land.
The worked example: what a higher rate does to the payment
To put numbers on it, take a $500,000 mortgage with a 25-year amortization and monthly payments, with a first five-year term at 2.50%. The rates in this example are chosen to show the shape of the problem across a range. They are not a statement about what any lender is offering now.
Canadian fixed-rate mortgage interest is compounded semi-annually rather than monthly, which follows from section 6 of the Interest Act: blended payments have to be computed on a rate calculated yearly or half-yearly, not in advance. The figures below use that convention.
Over that first term, the payment is $2,239.83 a month. Sixty payments total $134,389.87, of which $76,810.33 goes to principal and $57,579.54 goes to interest. At the renewal date the balance is $423,189.67, with 20 years of amortization left to run.
That balance and that 20-year remainder are what get repriced. Here is the same debt at a range of renewal rates:
| Renewal rate | Monthly payment | Change vs first term | Per year |
|---|---|---|---|
| 2.50% | $2,239.83 | $0 | $0 |
| 3.50% | $2,448.84 | +$209.01 | +$2,508.13 |
| 4.00% | $2,557.11 | +$317.28 | +$3,807.33 |
| 4.50% | $2,667.81 | +$427.98 | +$5,135.74 |
| 5.00% | $2,780.89 | +$541.05 | +$6,492.65 |
| 5.50% | $2,896.27 | +$656.44 | +$7,877.30 |
| 6.00% | $3,013.91 | +$774.08 | +$9,288.92 |
Data as of September 10, 2026, calculated on the scenario above.
Two things fall out of that table. The first is that the payment climbs almost linearly: every extra percentage point of rate costs between $209.01 and $233.02 a month on a balance this size, reading the differences straight off the rows. The second is that a difference of a quarter or a half point in the rate you negotiate is worth real money every month for five years. That is the case for treating the renewal statement as a starting position.
Lever one: negotiate, or move the mortgage
You are not obliged to renew with your current lender. FCAC is explicit that you can negotiate a rate below the one quoted on your renewal statement, and that offers from other institutions give you leverage. Be ready to prove those offers exist, because you may be asked to.
Switching lenders is a real application. The new lender has to approve your mortgage and may use different criteria than the one you are leaving. There are costs, and FCAC lists the types without dollar figures: setup fees with the new lender, which may include discharge, registration, transfer or assignment fees from your current lender, possibly an appraisal fee, and other administration fees. A new lender may agree to cover some or all of them, which is itself negotiable.
Two traps are worth knowing about before you start:
Mortgage loan insurance. You may have to pay a new premium if the loan amount increases or the amortization is extended. If your mortgage is already insured, give the new lender your certificate number so you are not charged a second time for coverage you already have.
Collateral charge mortgages. Switching one of these can cost extra in fees to remove the existing charge and register a new one, and you have to repay or transfer every loan secured by that charge. If a car loan or a line of credit sits behind the same collateral charge, they come along for the ride.
The stress test at renewal
This is where a lot of bad information circulates, and the insured and uninsured halves genuinely differ.
For uninsured mortgages, OSFI’s minimum qualifying rate is the greater of the contract rate plus a buffer, currently two percentage points, or a floor, currently 5.25%. OSFI states both of those as current values on its minimum qualifying rate page (site-modified January 29, 2026).
The important carve-out is on that same page: OSFI does not expect lenders to apply the minimum qualifying rate to uninsured straight switches at renewal. A straight switch means moving an uninsured mortgage from one federally regulated lender to another with no increase to the amortization period and no increase to the loan amount. Both conditions, not either.
On the insured side, the Department of Finance’s announcement of the mortgage reforms coming into force describes the strengthened Canadian Mortgage Charter as allowing insured mortgage holders to switch lenders at renewal without facing another stress test, and dates OSFI’s removal of the test for uninsured switches to November 21, 2024.
What is not covered by any of that: borrowing more, or stretching the amortization. Either one turns your renewal into a new application, with the qualifying math done afresh and possibly a new insurance premium. If that is your plan, the same three constraints that governed the original purchase apply again, and we worked through them in how much mortgage you can afford.
Lever two: stretching the amortization back out
When the payment jumps, the obvious fix is to re-extend the amortization. FCAC puts a warning at the very top of its renewal page, and it is worth quoting exactly: “Think twice before extending your amortization to lower your payments. The interest costs that you’ll need to pay will be higher. This may add up to thousands or tens of thousands of dollars.”
On our example, renewing that $423,189.67 balance at 4.50%, here is what “tens of thousands” means:
| Amortization at renewal | Monthly payment | Monthly saving | Total interest on this path | Mortgage-free |
|---|---|---|---|---|
| 20 years (stay the course) | $2,667.81 | $0 | $217,084.61 | 25 years after purchase |
| Re-extend to 25 years | $2,342.24 | $325.57 | $279,482.44 | 30 years after purchase |
| Re-extend to 30 years | $2,133.79 | $534.02 | $344,974.06 | 35 years after purchase |
Re-extending to 25 years costs $62,397.83 in extra interest. Going to 30 years costs $127,889.45 in extra interest, in exchange for $534.02 a month. And if that stretch happens as part of a switch, it is no longer a straight switch, so the qualifying test and a possible new insurance premium come back into the picture.
None of that makes the stretch wrong. If the alternative is missing payments, a longer amortization is the cheaper problem. But it should be a decision made with the $127,889.45 in view, not a checkbox on a renewal form.
Lever three: the money you can put in, and the payment you can keep
The renewal window is the moment a lump sum goes in cleanly. FCAC lists the end of your term among the times you can make a lump-sum payment, and paying above your privilege limit during a term triggers a prepayment penalty, so the renewal window is when a lump sum can go in without testing your prepayment limit. The details are on FCAC’s paying off your mortgage faster page (also dated October 15, 2025).
On our example, renewing at 4.50% over 20 years:
| Lump sum at renewal | New payment | Monthly saving | Interest saved over 20 years |
|---|---|---|---|
| $10,000 | $2,604.77 | $63.04 | $5,129.72 |
| $25,000 | $2,510.21 | $157.60 | $12,824.31 |
| $50,000 | $2,352.61 | $315.20 | $25,648.62 |
That works out to roughly fifty cents of interest saved per dollar prepaid, on this scenario’s numbers. Whether spare cash belongs against a 4.50% mortgage or inside an investment account is partly a question of the tax wrapper it would otherwise sit in, which is the argument our TFSA guide walks through.
The mirror image applies when the renewal rate is lower than the one you are leaving. FCAC points out that you can keep your payments the same and pay the mortgage off faster. Take a different example: a $400,000 balance with 20 years remaining, coming out of a 5.50% term into 4.00%. The old payment was $2,737.57 and the required new payment is $2,416.99. Keep writing the cheque for $2,737.57 and the mortgage is gone in 16.66 years, which is 3.34 years early, with $147,267.58 of interest instead of $180,076.61. That is $32,809.03 saved for doing nothing except not noticing a raise.
The statement is an opening offer
Renewal is the one moment in a mortgage when the balance is repriced, the amortization is adjustable, a lump sum faces no prepayment limit and a competitor’s rate is worth something. All four of those doors are open at the same time, and they close when you sign.
The 21-day notice is a floor, not a schedule. Shopping a few months out, with a competing quote in hand, is what turns the number on the renewal statement into a negotiation rather than an announcement.
Data as of September 10, 2026. FCAC pages dated October 15, 2025; the OSFI minimum qualifying rate page was site-modified January 29, 2026, and OSFI labels the two percentage point buffer and the 5.25% floor as current values. All payment and interest figures above are calculated on the stated example scenarios and are not quotes, offers or forecasts of market rates.
