Canada’s key core inflation gauge, the trimmed Consumer Price Index (trimmed CPI), edged down to 1.8% year-over-year in September 2026, from 1.9% in August 2026. The latest reading, updated on 19 October 2026, underscores a gradual cooling in underlying price pressures when compared with the same month a year earlier.
The trimmed CPI measure, which filters out the most volatile price movements, is closely watched as an indicator of underlying inflation momentum. On a year-over-year basis, both the August and September readings compare price changes in 2026 to their respective months in 2025, showing a modest but consistent easing pattern.
With trimmed CPI now below the 2% mark, the September data reinforces the narrative of softening core inflation in Canada. Market participants and policymakers will likely scrutinize whether this slowdown in underlying prices continues in the coming months as they assess the broader trajectory of inflation and the implications for future monetary policy decisions.
