Canada inflation rose to 3.1% in September 2026, up from 3.0% in August, according to Statistics Canada’s consumer price index released on October 19. The number came in slightly below the 3.2% economists expected, but it is still above the Bank of Canada’s 2% target, one week before the Bank’s October 28 rate decision.
The headline figure hides a split. Gasoline prices drove most of the increase, while the Bank’s preferred core measures actually eased. For mortgage borrowers, that split is the key to reading what comes next.
This guide explains what the September numbers show, what they mean for fixed and variable rates, and how Ontario homeowners and buyers can plan around them.

What drove Canada inflation in September
Energy was the main driver of Canada inflation last month. Gasoline prices were 27.8% higher than a year earlier, up from a 22.8% increase in August, and energy prices overall rose 19.0%. Oil started climbing again in early September, and the trade dispute with the United States has added to costs at the border.
Other parts of the Canada inflation basket were calmer. Grocery prices rose 1.7% year over year, down from 2.8% in August, and shelter costs rose 1.8%. Prices for services were up 2.6%. Excluding gasoline, Canada inflation was 2.2%, down from 2.4% the month before. The full breakdown is in investingLive’s summary of the release.
| Measure | September 2026 | August 2026 |
|---|---|---|
| Headline CPI | 3.1% | 3.0% |
| CPI excluding gasoline | 2.2% | 2.4% |
| CPI-trim | 1.8% | 1.9% |
| CPI-median | 1.9% | 2.0% |
| Gasoline | 27.8% | 22.8% |
| Food from stores | 1.7% | 2.8% |
| Shelter | 1.8% | n/a |
1. Core inflation is close to target
The Bank of Canada pays closest attention to its core measures, CPI-trim and CPI-median, because they strip out the most volatile price changes. In September, CPI-trim was 1.8% and CPI-median was 1.9%, both slightly below 2%.
That matters for Canada inflation because it suggests price pressure outside energy is not spreading through the economy yet. If core measures were rising alongside the headline, the case for a rate increase would be much stronger.
2. Ontario inflation is the lowest in the country
Ontario’s inflation rate was 2.5% in September, up slightly from 2.4% in August, but the lowest of any province. Atlantic provinces saw rates between 4.7% and 5.7%, and Alberta was at 3.6%, according to BNN Bloomberg’s provincial list.
Part of the reason Ontario sits below national Canada inflation is housing. Ontario rents and home prices have softened this year, which keeps shelter costs down. For Ontario households, the practical pressure is mostly at the gas pump rather than across the whole budget.
3. What Canada inflation means for the October 28 decision
The Bank of Canada has held its policy rate at 2.25% since October 2025. In September it warned that upside risks to inflation had increased, and its surveys released on October 19 showed businesses and households expecting higher prices ahead.
The September Canada inflation report gives each side something. A 3.1% headline and rising inflation expectations support a rate increase. Core measures below 2%, a slower monthly increase of 0.1%, and the loss of 68,000 jobs in September support another hold. Markets in mid-October still put better-than-even odds on a hold for October 28, with a hike seen as possible later in the year or in 2027.
4. Fixed rates respond to bond yields, not the CPI headline
Fixed mortgage rates follow the 5-year Government of Canada bond yield. That yield was 3.59% on October 6, about 84 basis points higher than a year earlier, and lenders have raised fixed rates since early September. The lowest insured 5-year fixed rate through brokers was about 4.34% in early October.
Bond markets react to Canada inflation reports, but they also react to oil prices, U.S. yields and the Bank’s tone. A softer core reading can calm yields for a few days, but it does not reverse the larger move on its own. If you are buying or renewing in the next four months, a rate hold through a pre-approval protects you from the next jump.
5. Variable rates depend on the Bank’s next move
Variable mortgage rates are priced off prime, which is 4.45% while the policy rate sits at 2.25%. Prime moves only when the Bank changes its policy rate, so Canada inflation affects variable borrowers through the Bank’s decision.
If the Bank raises its rate by 0.25%, a variable borrower with a $500,000 balance and 25 years remaining would pay about $68 more a month on an adjustable-rate mortgage. If the Bank holds, nothing changes. You can test your own balance with the mrates.ca mortgage calculator.
6. Inflation also affects how much you qualify for
Lenders count your living costs when they assess an application, and higher fuel and grocery bills reduce the room in your budget. The stress test also qualifies you at the higher of your contract rate plus 2% or 5.25%, so any rate increase triggered by Canada inflation reduces your borrowing power.
On the positive side, wage growth has kept pace with prices for many workers, and lower core inflation means the Bank may not need to raise rates far. Buyers with stable income and a pre-approval in hand are in a better position than those waiting to see where rates land.
Will Canada inflation push rates higher?
Here are both sides of the question.
The case that rates will rise
- Headline Canada inflation is above 3% and has risen for two months in a row.
- Energy costs feed into transport, shipping and food prices with a delay.
- The Bank’s own surveys show businesses planning to pass higher costs on to customers.
- Bond markets are already pricing increases over the next year, which keeps fixed rates high.
The case that rates will hold
- Core inflation measures are below 2%.
- The monthly increase in September was only 0.1%.
- The job market weakened sharply in September, which usually lowers price pressure.
- Gasoline-driven inflation can fade quickly if oil prices fall.
For borrowers, the safest response to Canada inflation is to prepare for both outcomes rather than bet on one.
What borrowers can do now
- If you are renewing before mid-February 2027, ask your lender or broker for a renewal rate hold.
- If you are buying in the next four months, get a pre-approval with a rate hold.
- If you have a variable rate, check whether your payment adjusts or stays fixed when prime changes.
- Build fuel and grocery increases into your monthly budget before applying.
- Compare offers from more than one lender before signing.
