Inflation rises to 3.1% in September as gasoline jumps, but core measures cool

Canada's annual inflation rate edged up to 3.1% in September from 3.0% in August, Statistics Canada said Monday, as a surge in gasoline and heating fuel prices pushed the consumer price index back above the upper end of the Bank of Canada's 1% to 3% control range for the first time in three months.

The details were less alarming than the headline. Excluding gasoline, prices rose 2.2%, down from 2.4% in August, and the central bank's preferred core measures both slowed. Grocery inflation also eased sharply.

The numbers versus expectations

Economists polled by Reuters had expected headline inflation of 3.2%, so the result came in slightly soft. The key figures:

Statistics Canada noted that the switch to cheaper winter-blend gasoline moderated the monthly increase at the pump.

• All-items CPI: +3.1% year over year (August: +3.0%)
• Monthly change: +0.1% unadjusted, +0.4% seasonally adjusted
• CPI excluding gasoline: +2.2% (August: +2.4%)
• CPI-median: 1.9%, CPI-trim: 1.8%, both slightly below the 1.9% economists expected
• Energy: +19.0% (August: +15.4%); gasoline +27.8%; fuel oil and other fuels +57.8%
• Food purchased from stores: +1.7%, the smallest yearly gain since May 2024
• Shelter: +1.8% (August: +1.5%); rent +2.8%; mortgage interest cost -0.2%

An energy shock, not a broad one

The story of 2026 inflation in Canada is increasingly a story about oil. Statistics Canada linked the gasoline increase to crude prices reaching their highest level since May amid uncertainty over conflicts in the Middle East. Fuel oil, which many households in Atlantic Canada rely on for heating, was up 57.8% from a year earlier, and air transportation rose 19.4%.

Outside energy, the picture is close to the Bank of Canada's 2% target. Continuum Economics pointed out that seasonally adjusted prices excluding food and energy rose just 0.1% in the month, after four straight gains of 0.3%. Grocery prices are still 33.0% higher than in September 2020, but fresh vegetables fell 2.9% over the past year.

Why the Bank of Canada may still worry

The risk is that an energy shock seeps into expectations. On the same day, the Bank of Canada's third-quarter consumer survey showed long-term inflation expectations rising to match elevated short-term expectations, with respondents citing trade tensions and energy prices. Firms in the Business Outlook Survey said they plan to keep passing on larger-than-normal cost increases.

Bond markets reacted to the headline: the two-year Government of Canada yield rose 7.7 basis points to 2.545%, according to Reuters. Money markets expect the Bank to hold its policy rate at 2.25% on October 28 but have priced in a quarter-point hike in December. Governor Tiff Macklem has said the Bank's new forecasts will show higher inflation.

What it means for Canadian households

For most families, the pain is concentrated at the pump and in heating bills, while grocery and rent increases are slowing. Households heating with oil, particularly in Atlantic Canada, face the biggest squeeze heading into winter.

For borrowers, the more important signal is the bond market. Fixed mortgage rates track government bond yields, so anyone renewing in the coming months may see less relief than they had hoped for if markets keep pricing in a rate hike. Savers, meanwhile, should compare what their savings accounts and GICs pay against a 3.1% inflation rate: a return below that figure is losing purchasing power.
