Bank of Canada on October 28: Why Your Mortgage Plan Shouldn't Hinge on the Decision
On a $500,000 mortgage, a quarter-point move in the Bank of Canada's rate on October 28 works out to roughly $70 a month. That's illustrative arithmetic, using a 25-year amortization with the semi-annual compounding Canadian mortgages use: about $2,767 a month at 4.50%, and about $2,698 at 4.25%. Real money, and small next to the decisions people are holding back while they wait for it.
The Bank of Canada has held its rate for roughly a year, and markets are betting that pause ends next week. Some experienced mortgage people aren't convinced. When the forecasts split like that, the useful move for a buyer or a renewing homeowner is to build a plan that works under either outcome. The rate decision becomes one input, and the anchor becomes the payment your household can carry comfortably for the next five years.
Fixed and variable rates answer to different signals
The overnight rate moves Prime, and Prime moves variable mortgages. Fixed rates take their cue from the bond market, and bond traders price in what they expect the Bank to do weeks or months before it acts. If a move is widely expected, much of it is already sitting in today's five-year fixed offers.
That creates an odd possibility. The Bank could cut on October 28 and fixed rates could stay flat or tick up, if bond investors worry that inflation will return. Statistics Canada reported that headline inflation ran at 3.1% in September 2026, driven largely by gasoline, while core measures eased, so the Bank has reasons to move in either direction, and none of them is a promise. The Bank also watches the U.S. Federal Reserve and the dollar, and it knows rate changes take a long time to fully work through the economy, so a cautious hold is a reasonable outcome too.
The practical lesson: a cut helps variable borrowers directly and fixed borrowers only partly, and possibly not at all on announcement day.
The stress test already shows you your margin
Every uninsured borrower in Canada has to qualify at the greater of their contract rate plus 2 percentage points, or 5.25%, under OSFI's rule. On that same $500,000 example at a 4.50% contract rate, the lender checks whether you could handle payments at 6.50%, which is about $3,349 a month.
Put the numbers side by side. A quarter-point move is worth about $70. The cushion the stress test asks you to prove is about $580 above your actual payment. Affordability decides far more about your financial life than the next quarter point does, and you control most of it: down payment, amortization, how much other debt rides along, and what monthly figure leaves your family breathing room.
British Columbians tend to carry larger balances relative to home values, so every rate move registers more in the monthly budget. Even so, BC borrowers have been managing: the provincial mortgage delinquency rate was 0.25% in the first quarter of 2026. People who planned around a payment they could handle have mostly been fine through a much harder stretch than this one.
Make the choice on payment, then on flexibility
If you're buying in the Cowichan Valley this fall, or renewing a mortgage that was taken out when rates were far lower, try this sequence. Start with the payment you'd still be comfortable with if rates went nowhere for two years. Then pick the product that protects that number.
If you want the chance to benefit from future cuts and can absorb some movement, a variable rate keeps that door open, and its penalty is typically three months' interest if you need to break it. If a steady payment matters more to your household, a fixed term buys certainty, and you can compare its rate against the variable to see how many cuts it would take to break even. The Bank of Canada publishes its own estimate of the neutral rate, which gives a rough sense of how far rates might settle over time and is useful for that break-even math.
Whatever the Bank announces on Wednesday, run your plan twice: once with a rate change, once without. If it only works in one of those versions, the plan needs adjusting before the announcement does it for you.
