How the payment is worked out. Canadian fixed-rate mortgages compound semi-annually, not monthly. The monthly rate used here is (1 + annual rate ÷ 2) to the power of one sixth, minus one — the method set out in chapter 4 of the book. Variable-rate mortgages compound monthly, and this calculator uses annual rate ÷ 12 wherever a variable rate is entered. A calculator built for an American or British mortgage uses the monthly method for everything and will give you the wrong payment for a Canadian fixed mortgage.

Any rate already filled in is as at September 2026 — Bank of Canada policy rate 2.25%, prime 4.45% at the six major banks, posted five-year 6.09%, best available five-year fixed about 4.24%. Rates move weekly and fixed rates move with the five-year Government of Canada bond yield, sometimes daily. Check yours before you rely on any of this.

General information, not financial advice. This is math on the numbers you type. Nothing you enter is stored, saved or sent anywhere — there is no account and no cookie, and your numbers never leave this page. All figures are Canadian dollars (CAD). Check your own numbers with your lender or a licensed mortgage broker.

Why ninety days

Because it is roughly the lead time FCAC recommends before a renewal, and because it is long enough to switch lenders and short enough that you will not lose interest. If your renewal is sooner, do it in the same order, faster.

The whole book in ten lines

  • Your renewal is a negotiation that arrives looking like a form.
  • You have 21 days of protected notice and your lender cannot make the offer worse inside it.
  • Do nothing and you may be renewed automatically into whatever was on the form.
  • The stress test on switching lenders came off on 21 November 2024 for uninsured straight switches, and in 2023 for insured. Most Canadians were never told.
  • The exemption is narrow: federally regulated to federally regulated, no amortization increase, no loan increase beyond $3,000, stand-alone mortgage.
  • You cannot switch lenders and extend your amortization in the same transaction.
  • The posted rate you never pay is the number your bank uses to build your penalty.
  • Pay the highest rate first, always, and a 0% student loan is last.
  • Renewal shock shows up on the Visa before it shows up on the mortgage.
  • Every rate, every privilege, every penalty formula and every relief measure goes in writing.

If the numbers do not work

Start this week rather than at the end of the ninety days, and do these in order. Every one of the conversations is free.

Your lender's mortgage assistance team, before a payment is missed rather than after. FCAC expects federally regulated lenders to proactively contact at-risk mortgage holders and offer relief — extending the amortization, waiving its own fees, waiving prepayment penalties on a lump sum or a consumer-led sale. They made over 47,000 contacts and delivered 8,466 measures, and more than 5,000 offers were declined. Roughly as many households refused help as took it. Shame is expensive. Ask what it costs in total interest, what is reported to the credit bureaus, and whether it affects your ability to switch later.

A non-profit credit counsellor. The first session is free and no agency may charge a fee up front. Confirm membership of Credit Counselling Canada, and ask for the fees in dollars in writing before signing anything. A debt management program deals with unsecured debt only — it does not touch your mortgage.

A Licensed Insolvency Trustee. Only a trustee can file a consumer proposal or a bankruptcy in Canada. And here is the fact most Canadians have backwards: the $250,000 limit on a consumer proposal explicitly excludes a mortgage secured by your principal residence, and an accepted proposal lets you retain your assets provided you keep paying your secured creditors. You can compromise the cards and keep the house. Ask an LIT what a proposal would do to your ability to renew and to switch lenders, because this book could not answer that and they can.

What actually works

The households that come through a renewal shock are not the ones who found a clever move. They are the ones who found out their real numbers early, made three or four small changes instead of one large one, and asked for the rate rather than accepting the one they were sent. None of that requires expertise. It requires about four hours, spread over ninety days, and the willingness to make a phone call you would rather not make.

Check this one. Every figure in this plan moves. Before you act, check the policy rate at bankofcanada.ca, the minimum qualifying rate and the straight-switch conditions at osfi-bsif.gc.ca, the renewal rules at canada.ca under the Financial Consumer Agency of Canada, and your own numbers with your lender and a mortgage broker. Your renewal date and balance come from your renewal statement, not from memory.

The Canadian Mortgage Handbook

The rule that kept you with your lender changed in 2024. Nobody told you.

  • Uninsured straight switches no longer face the stress test (since November 21, 2024)
  • Why the posted rate you never paid drives your prepayment penalty
  • Your trigger rate: how to find it and what happens when you reach it
  • Prepayment room that's gone on the reset date if you don't use it
