Consumer Price Index, September 2023
In September, the Consumer Price Index (CPI) rose 3.8% on a year-over-year basis, down from a 4.0% gain in August. The year-over-year deceleration was broad-based, stemming from lower prices for some travel-related services, durable goods and groceries.
Offsetting the deceleration in the all-items CPI was a year-over-year increase in gasoline prices, which rose at a faster pace in September (+7.5%) compared with August (+0.8%) due to a base-year effect. Excluding gasoline, the CPI rose 3.7% in September, following a 4.1% increase in August.
On a monthly basis, the CPI fell 0.1% in September, after a 0.4% gain in August. The monthly slowdown was mainly driven by lower month-over-month prices for gasoline (-1.3%) in September. On a seasonally adjusted monthly basis, the CPI rose 0.2%, stemming from travel-related services.
Price growth for groceries continues to slow, but remains elevated
Price growth for groceries continued to slow in September but remained above headline inflation, rising 5.8% year over year, following a 6.9% increase in August. The deceleration stemmed from year-over-year slowdowns in meat (+4.4%), dairy products (+4.0%) and coffee and tea (+2.7%), which were mainly driven by base-year effects. Large monthly gains in September 2022, when grocery prices increased at the fastest pace in 41 years, fell out of the 12-month movements and put downward pressure on the indexes.
In contrast, prices for fresh fruit (+3.0%), fish (+5.1%), bakery products (+8.0%) and edible fats and oils (+14.8%) increased at a faster pace on a year-over-year basis in September compared with August.
Consumers pay less for airfares
Consumers paid less on a year-over-year basis for air transportation (-21.1%) in September, coinciding with a gradual increase in flights offered by airlines over the previous 12 months.
Prices for durable goods decelerate
Prices for durable goods rose at a slower pace year over year in September (+0.4%) compared with August (+1.4%). The purchase of new passenger vehicles index contributed the most to the slowdown, rising 1.7% year over year in September, following a 3.1% gain in August. The deceleration in the price of new passenger vehicles was partly attributable to improved inventory levels compared with a year ago.
Additionally, prices for furniture (-4.6%) and household appliances (-2.3%) continued to decline on a year-over-year basis in September, also contributing to the slowdown in durable goods.

Year over year, prices increased in all provinces in September but rose at a slower pace compared with August in six provinces.
Gasoline prices accelerate on base-year effect
Year over year, gasoline prices rose 7.5% at the national level in September, following a 0.8% increase in August. The increase was mainly driven by a base-year effect, as prices fell 7.4% month over month in September 2022, amid an increase in global supply of crude oil.
Prices at the pump accelerated the most in Eastern Canada on a year-over-year basis in September 2023. In Western Canada, refinery shutdowns limited supply in September 2022, which kept gasoline prices higher that year. As a result, gasoline prices in western provinces did not fall to the same extent from August to September 2022.
