Canada’s Raw Materials Price Index (RMPI) rose at a faster pace in September 2026, underscoring mounting cost pressures at the early stages of the production chain. The index increased 4.8% month-over-month, up from a 3.1% gain in August 2026, according to data updated on 22 October 2026.
On a month-over-month basis, the “actual” September figure reflects the change from August to September, while the “previous” reading captures the change from July to August. The acceleration from 3.1% to 4.8% suggests that input prices for Canadian manufacturers and producers are rising more sharply, potentially feeding into downstream production and consumer prices in the coming months.
