Interest Rates and the Montreal Market

By Georges Matar · July 13, 2026 · 6 min read

Interest rates are the variable buyers follow most anxiously and understand least well. A headline announces a Bank of Canada decision, and the question that follows is always the same: does my payment change?

Often it does not. Not right away, not automatically, and not in the same way depending on whether your rate is fixed or variable. Here is the real path, with official figures current as of 21 September 2026. You will find no forecast here. Nobody knows the next rate, and I am no exception.

What the Bank of Canada Sets, and What It Does Not

The Bank of Canada announces its policy rate on eight pre-set dates each year. On 2 September 2026 it held that rate at 2.25%, the level in place since 29 October 2025. The two remaining 2026 announcements are scheduled for 28 October and 9 December.

That rate does not set your mortgage. It sets the cost of overnight funding between financial institutions. Everything else, the prime rate, variable mortgage rates and fixed mortgage rates, follows from it along different paths and at different speeds.

For context on what the Bank watches: the Consumer Price Index rose 3.0% year over year in August 2026, according to Statistics Canada in its release of 14 September 2026.

Variable Rates Travel Through the Prime Rate

The prime rate at the major chartered banks is the reference for variable mortgages, and it moves roughly in step with the policy rate. As of 16 September 2026, the Bank of Canada reported a prime rate of 4.45%, which is 2.20 points above the 2.25% policy rate.

A variable mortgage is therefore written in relation to that number, in the form of prime minus a discount. When the Bank moves and the banks follow, your rate moves within days, with no renegotiation.

Two different mechanics hide behind the word variable, and you should ask which one applies to you. On an adjustable payment variable mortgage, the payment itself changes with the rate. On a fixed payment variable mortgage, the payment stays the same and the split between principal and interest shifts instead: a rate move is then paid in time rather than in monthly cash. Ask before you sign, not at renewal.

Fixed Rates Travel Through the Bond Market

Fixed rates do not follow the policy rate. They follow the cost of term funding, and the clearest public indicator of that is the yield on Government of Canada bonds. As of 17 September 2026, the Bank of Canada published benchmark yields of 3.27% at 2 years, 3.54% at 5 years and 3.83% at 10 years.

The practical consequence is that a fixed rate can move on an ordinary Tuesday, with no Bank of Canada announcement, because the bond market moved. It can also sit still on decision day, because the decision was already priced in.

Pay attention to which rate you are reading. On 16 September 2026, the posted 5 year conventional mortgage rate compiled by the Bank of Canada stood at 6.09%. That is a posted rate, not a negotiated one: it serves as a statistical reference, not as a street price. The comparison that matters is between real offers made on your file, which is what the honest guide to getting the best mortgage rate walks through.

What One Percentage Point Does to Borrowing Capacity

What follows is an amortization calculation, not a forecast. The two rates below are calculation assumptions, not quotes available today. Canadian convention applies: interest compounded semi annually, monthly payments, 25 year amortization, principal of $500,000.

At 4.00%, the monthly payment works out to roughly $2,630.
At 5.00%, it works out to roughly $2,908.

One percentage point therefore adds about $278 per month. Turn the question around and the effect lands harder: at an identical payment of $2,630 a month, the principal that payment can carry falls from roughly $500,000 to roughly $452,000. Close to 10% less buying power, with nothing changed in your income or your credit file. Your own lender will apply its own rounding, insurance premium and payment frequency, so treat these as orders of magnitude rather than as a quote.

Run the same calculation on your own numbers with the mortgage calculator and the affordability calculator.

The Stress Test: You Qualify Above Your Own Rate

At a federally regulated lender, the minimum qualifying rate is the greater of your contract rate plus 2 percentage points, or 5.25%. The Office of the Superintendent of Financial Institutions maintains that rule and confirms it on its dedicated page, last updated 29 January 2026.

A less familiar point sits on the same page: OSFI does not require lenders to apply the minimum qualifying rate when a borrower switches an uninsured mortgage from one federally regulated lender to another without extending the amortization period or increasing the loan amount. At renewal, that opens the door to shopping around rather than signing the offer that arrives in the mail.

Renewal Shock, With the Public Numbers

The most concrete rate story right now is not purchasing. It is renewal. In its Housing Observer article of 5 February 2026, Canada Mortgage and Housing Corporation wrote that more than 1.5 million households had already renewed at higher interest rates, and that another million were set to sign new terms in the coming year.

The same analysis notes that the national mortgage arrears rate rose by 7 basis points between the third quarter of 2023 and the third quarter of 2025, and describes delinquency risk in Montreal as stable. A real, measurable increase, to be read for exactly what it is.

What you can do: ask your lender for the projected renewal payment four to six months before maturity, then compare against another lender and a mortgage broker. A renewal is negotiable.

What the Montreal Market Is Showing Right Now

In August 2026, across the Montreal CMA, APCIQ recorded 2,853 sales, down 13% year over year, and 20,128 active listings, up 18%. Median prices were still higher than a year earlier: $650,000 for single family homes, up 3%, $437,250 for condominiums, up 4%, and $856,000 for plexes, up 2%. Average days on market were 42 for single family homes, 62 for condominiums and 52 for plexes. Those figures come from the APCIQ monthly statistics compiled through the Centris system and released on 4 September 2026.

Fewer transactions, more choice, and median prices that are not falling. That is what the data says, and nothing more. I go deeper into that reading in what the data actually says about the Montreal market.

What You Control, Instead of Guessing

Next month’s rate is not within your reach. The rest is.

Your down payment. It changes the principal, the mortgage insurance premium and the payment. See the 20% down payment myth.
Your term length. A short term brings you back to the market sooner, a long term locks you in longer. That is a trade off, not an answer.
Your other debts. They enter the ratios before the rate does.
Your credit score. It is built months in advance, not in a week.
The gap between your approved maximum and a comfortable budget. That gap is the only buffer protecting you at a higher renewal rate. A pre approval states a ceiling, not a target, as the pre approval trap explains.

None of those decisions depends on a forecast. All of them are made with today’s numbers.
