Annual consumer-price inflation was 3.1% in both Canada and Quebec in September 2026, according to the Institut de la statistique du Québec’s update of 19 October. Canada’s rate rose from 3.0% in August, while Quebec’s was unchanged at 3.1%. The institute adapts Statistics Canada’s CPI data.
Gasoline prices were 27.8% higher than a year earlier in Canada and 22.8% higher in Quebec. Excluding gasoline, annual CPI growth was 2.2% and 2.4% respectively. These are non-seasonally-adjusted comparisons with September 2025, not monthly changes or price-index levels.

Measurement and privacy details
Google Analytics measurement starts only if you allow it. After consent, automatic measurement may cover scrolls, outbound link clicks, downloads, video engagement, site searches and basic form interactions; search terms may be detected from URL parameters. This site’s own code does not send form field values; email redaction in automatic measurement is best-effort, not guaranteed. Our manual page-view event uses a cleaned URL. You can change your choice later. Visits that begin with consent may also send numeric LCP, INP and CLS performance measurements after Analytics loads. A first or later grant starts this on the next page load; withdrawing consent stops these performance reports for this page. The preference cookie lasts six months; advertising measurement and personalization stay off.
