Canada’s annual inflation rate rose to 2.4 % in September 2025, up from 1.9 % in August and slightly above what economists had anticipated. The increase was driven largely by a smaller-than-expected reduction in gasoline prices and a noticeable uptick in food and shelter costs. This marks the first time in several months that headline inflation has moved higher, interrupting the downward trend seen through much of the year.
Breaking down the numbers: gasoline prices, which had been declining year-over-year, fell less in September than they did in the same period a year ago, lessening their drag on headline inflation. Food prices climbed 3.8 % year-over-year, with grocery purchases seeing their highest rise since early 2024. Shelter costs also contributed, with rents up 4.8 %, adding continued pressure on households already facing affordability challenges.
Core inflation measures remain stubborn. The Bank of Canada’s preferred gauges — CPI-median and CPI-trim — were around 3.2 % and 3.1 %, respectively. This suggests that even though headline inflation appears moderate, underlying price pressures are still embedded across key sectors such as housing, insurance, and services.
The data has immediate implications for the Bank of Canada’s upcoming policy meeting on October 29. Markets had widely expected a 25-basis-point rate cut, which would have lowered the policy rate to around 2.25 %. However, the stronger-than-expected inflation reading has reduced those odds, as policymakers may now opt to wait for clearer evidence that inflation is sustainably moving toward the 2 % target before easing further.
For households and businesses, this could mean borrowing costs remain higher for longer than anticipated. Mortgage holders, particularly those with variable rates, may continue to feel pressure, while potential homebuyers could face tighter conditions heading into the winter housing season.
In summary, while inflation remains within the Bank of Canada’s 1 %-to-3 % control range, the unexpected rise highlights the delicate balance between supporting economic growth and preventing renewed price acceleration. The next few weeks of economic data will be crucial in determining whether the central bank stays the course or begins its long-anticipated rate-cutting cycle.
