The Consumer Price Index (CPI) rose 2.4% on a year-over-year basis in September, up from a 1.9% increase in August. The acceleration in headline inflation from 1.9% in August was also larger than the median projection in a Bloomberg survey of economists, which was 2.2%.
On a year-over-year basis, gasoline prices fell less in September (-4.1%) compared with August (-12.7%) due to a base-year effect, leading to an acceleration in headline inflation. Excluding gasoline, the CPI rose 2.6% in September, after increasing 2.4% in August.
A slower year-over-year decline in prices for travel tours (-1.3%) and a larger increase in prices for food purchased from stores (+4.0%) also contributed to the upward pressure in the all-items CPI in September.
The CPI rose 0.1% month over month in September. On a seasonally adjusted monthly basis, the CPI was up 0.4%.
Gasoline prices fell 4.1% year over year in September after a 12.7% decrease in August. The smaller year-over-year decline was primarily due to a base-year effect. In September 2024, prices fell 7.1% month over month due, in part, to lower crude oil prices amid growing concerns of weaker economic growth, particularly in China and the United States. In September 2025, gasoline prices rose 1.9% monthly following refinery disruptions and maintenance in the United States and Canada, which put upward pressure on prices.
On a year-over-year basis, prices for travel tours fell 1.3% in September following a 9.3% decline in August. Despite typically declining on a month-over-month basis in September, travel tour prices rose 4.6% in the month. This was a result of higher prices for destinations in Europe and some parts of the United States, as significant events in destination cities put upward pressure on hotel prices.
Consumers paid 4.0% more year over year for food purchased from stores in September, following a 3.5% increase in August. Faster price growth was driven by increased prices for fresh vegetables (+1.9% in September, compared with -2.0% in August) and sugar and confectionery (+9.2% in September, compared with +5.8% in August).
Year-over-year grocery price inflation has generally trended upward since its most recent low in April 2024 (+1.4%). Grocery items contributing to the general acceleration included fresh or frozen beef and coffee, both due, in part, to lower supply.
Tuition fees, priced annually in September, increased 1.7% in 2025 compared with a 1.8% increase in 2024. Aside from 2019, the 2025 increase was the smallest since 1976, when the index was unchanged (0.0%).
In 2025, students from Prince Edward Island (+4.7%) experienced the largest price increase. At the same time, students from Nova Scotia (+1.1%) and Ontario (+1.1%) had the smallest increase, coinciding with a freeze on tuition fees in both provinces. |
