Statistics Canada reported that the Consumer Price Index rose 3.2% year over year in May 2026, up from a 2.8% increase in April.
Gasoline was the main reason the headline number moved higher. Prices at the pump rose 33.2% from a year earlier, compared with a 28.6% increase in April, as supply uncertainty continued to put pressure on energy prices.
The increase was not limited to gasoline. Excluding gasoline, prices rose 2.2% year over year in May, compared with 2.0% in April. On a monthly basis, the all-items index rose 1.0%, while the seasonally adjusted monthly increase was 0.5%.
Food remained a visible pressure point for households. Prices for food purchased from stores rose 4.3% year over year, marking the 16th consecutive month in which grocery inflation outpaced headline inflation. Fresh vegetables rose 9.0%, while tomato prices were up 45.2% after supply contractions in Mexico.
Shelter prices continued to cool, but only gradually. Statistics Canada said shelter rose 1.7% year over year in May, after a 1.8% increase in April. Rent inflation slowed to 3.5%, the lowest pace since January 2022, while mortgage interest costs continued to decelerate.
Transportation costs rose 9.0% year over year. Air transportation prices were up 7.4% after falling in April, and travel tours also moved higher as fuel and operating costs affected travel-related services.
For households, the May report points to renewed pressure in everyday costs even as shelter inflation continues to ease. For tax and public-finance readers, CPI matters because many benefit amounts, credits, thresholds, and budget assumptions are built around inflation and purchasing power.
