What the Bank of Canada's October Move Means for Your Mortgage

One thing moved on October 28. The other did not.

On October 28, 2026, the Bank of Canada raised its policy setting by 25 basis points to 2.5% — the first increase since July 2023, according to the Bank's own announcement that morning. By the next day, large lenders had moved their prime lending figure from 4.45% to 4.70%, with CIBC and National Bank each publishing notices on announcement day confirming the change effective October 29. If you hold a variable product or a HELOC, that is the part of this you can actually feel in your account.

What did not move mechanically that day is fixed pricing. Fixed terms are funded off Government of Canada bond yields of matching length, and the bond market had formed its view weeks earlier. Trading Economics shows the five-year Government of Canada yield at 3.58% on October 27, down roughly 0.11 points over the preceding month, although up about 0.95 points over the year. The announcement was widely expected, and expectations land in the price before the press conference, not after it.

So the advice circulating this week — lock in before it's too late — is asking you to buy a view the bond market already holds. Locking in may still be the right call for your household. It is not the right call because of what happened on Wednesday.

Two machines, two sets of inputs

The policy setting feeds lender prime. Prime sets what variable-product and HELOC holders pay, and that transmission is immediate and arithmetic: the announcement lands, prime moves, your cost of borrowing moves with it.

Fixed pricing runs on a different track. Lenders fund five-year money out of the bond market, so five-year pricing follows the five-year yield, continuously, every trading day, on expectations and term premium rather than on announcement dates. This is why two people can read the same headline and face entirely different facts.

Which borrower are you?

Before deciding anything, find out which of these four describes your mortgage. Most people we speak to this week are guessing.

• Adjustable-payment variable. Your payment itself repriced with prime. You will see a larger withdrawal and you will know about it quickly.
• Fixed-payment variable. Your payment held steady. The split between principal and interest shifted, so less principal retires each month and your trigger point moved closer. Nothing in your inbox will say so.
• HELOC or readvanceable line. Interest-only payments on the line move directly with prime.
• Mid-term fixed. Nothing changed for you until your maturity date, which is the date worth putting in your calendar today.

The fixed-payment variable group is the one nobody writes for, and it is the one with a silent change. Variable products compound monthly, so the arithmetic is straightforward. On a $400,000 balance, one month's interest at 3.65% is $1,216.67; at 3.90% it is $1,300.00. That extra $83 or so comes out of principal rather than out of your chequing account. Illustrative only — your own figures depend on your balance, your discount off prime and your lender's trigger terms.

If you are in that group, the useful next step is not a product change. It is finding out how much room sits between your current payment and your trigger point, and whether raising your payment voluntarily is cheaper than being forced to later. Our calculators will get you a first estimate in a few minutes.

If you are renewing in the next year

The most expensive habit in Canadian mortgages is signing the renewal letter because switching sounds like paperwork. Under OSFI's B-20 guideline, uninsured borrowers at federally regulated lenders qualify at the greater of their contract pricing plus a 2% buffer or a 5.25% floor. Crucially, that minimum qualifying figure has not been expected to apply to a straight switch of an uninsured mortgage to a new federally regulated lender since late 2024. The inertia argument is weaker than most people believe.

It is also worth seeing the renewal in dollars rather than in percentages. Canadian fixed mortgages compound semi-annually, not monthly, so the effective monthly figure is (1 + annual/2)^(1/6) − 1. On a $400,000 balance over a 20-year amortization, illustrative payments work out as follows:

• At 3.95%: $2,406.65 per month
• At 4.25%: $2,469.02 per month
• At 4.50%: $2,521.62 per month
• At 4.75%: $2,574.78 per month

Those gaps are the real decision — a few dozen dollars a month, compounding into a household budget over five years. CMHC's 2026 Mortgage Consumer Survey, published in May and now five months old, found 35% of renewers faced higher payments, up an average of $375 a month. Start the conversation in the 120-day window before maturity, not in the final week when your only live option is the letter in front of you.

Ontario's picture is not the national one

CMHC's report of October 27, 2026 puts Ontario's mortgage arrears figure — 90 days or more past due — at 0.32% in Q2 2026, up from 0.21% a year earlier, and expects it to keep climbing through mid-2027. The report names the Greater Toronto and Hamilton Area and southwestern Ontario specifically, where trade tensions are weighing on manufacturing, including the automotive sector. Meanwhile CMHC expects Alberta and Saskatchewan to improve on stronger energy conditions. The same energy shock pushing the Bank's hand is helping one region's balance sheets and pressing on ours.

Two second-order points from that report matter more locally than the headline figure. First, CMHC notes that softer resale conditions make it harder for a stretched borrower to sell or refinance out of trouble — that is the mechanism that turns a payment problem into an arrears problem, and it is the argument for starting early rather than at the letter. Second, CMHC identifies mortgage investment entities and other private lenders as the group showing the sharpest rise in arrears. If you took private financing in 2024 or 2025 intending to move to an A lender later, that exit is narrower than it was.

Keep the proportion right. CMHC also says arrears remain below the historical peaks of the past thirty years and that the largest renewal shock has likely passed. This is a specific regional pressure, not a national emergency — and it is the reason we look at a Waterloo Region file differently than we would one in Calgary.

Term length is a decision about timing, not a forecast

Here is what the Bank itself published alongside the decision. The October 2026 Monetary Policy Report projects inflation above 3% through much of 2027 — roughly one percentage point higher than its July projection — before returning close to the 2% target by mid-2028. Growth is projected at 1% in 2026 and 2% in each of 2027 and 2028. Statistics Canada's September 2026 release shows CPI up 3.1% year over year, with transportation up 8.4% and shelter up 1.8%.

The Bank's new disaggregated model, Prima, estimates that the rise in energy prices since the start of 2026 adds around two percentage points to inflation at their peak. The Governing Council said it would proceed carefully and did not rule out further increases. That is a statement of uncertainty, not a schedule.

Which brings the term question into focus. A five-year fixed term prices straight through a window the Bank itself expects to look different by the back half. That is not an argument for variable, and we will not pretend to know where pricing lands in 2029. It is an argument that choosing a term is really choosing when you next face the market. A three-year term puts you back at the table in 2029; a five-year puts you there in 2031. Pick the date you would rather negotiate on, given your own income stability, your plans for the house, and how much month-to-month variation your budget tolerates.

The MPR also projects residential investment growing by slightly less than 1% on average across 2027 and 2028, with higher energy and imported input costs making construction more expensive. For anyone waiting on new supply to fix affordability in this region, that projection is worth reading before building a plan around it.

What to actually do in the next thirty days

None of the above tells you to act. Most people reading this should do nothing except find out where they stand. In order:

• Open your mortgage statement and confirm whether your variable product is adjustable-payment or fixed-payment. This single fact changes everything else.
• Write your maturity date somewhere you will see it, and count back 120 days. That is when the renewal conversation should start.
• If you are in a fixed-payment variable, ask your lender for your current trigger point and the balance of room you have left.
• If you are thinking about breaking a term, get the payout quote from your lender in writing. A fixed-term penalty is typically the greater of three months' interest or an IRD calculation, lenders compute IRD by different published methods, and no online estimate is binding.
• If you have private financing maturing in 2027, start the exit conversation now rather than ninety days out.

An announcement is a data point. A plan is what survives several of them. The reason we say most people are handed a product rather than a plan is that products get chosen on announcement days, and plans get built on the dates in your own contract.
