Canadian headline inflation was 3.0% in August, while the Bank of Canada core measures CPI-trim and CPI-median stood at 1.9% and 2.0%. That gap of about one percentage point, between the number households see and the numbers the Bank targets, frames the October 28 rate decision.

Headline inflation passed CPI-trim and CPI-median in March 2026, rising to 2.4% from 1.8% in February against readings of 2.2% and 2.3%. It reached 3.2% in May and held at 3.0% in July and August, according to Bank of Canada data. CPI-common is the outlier among the core measures at 2.6%.

Statistics Canada publishes September CPI on Monday, October 19, nine days before the Bank decides. The Labour Force Survey on October 9 showed a loss of 68,000 jobs against a Reuters consensus gain of 9,200, and the unemployment rate rose to 6.5% from 6.4%.

Headline CPI has run above CPI-trim and CPI-median since March while CPI-common has stayed between 2.5% and 2.7% in 2026, so the Bank core measures are not telling a single story.

CPI-trim excludes the components with the most extreme price changes, CPI-median is the middle price change in the basket, and CPI-common tracks price movements shared across categories. Headline inflation is the year over year change in all-items CPI.

What the Core Measures Are Actually Saying

CPI-trim removes the components with the most extreme price changes, CPI-median takes the middle price change across the basket, and CPI-common tracks price movements shared across categories. In September 2025, CPI-trim and CPI-median were both 3.1% and CPI-common was 2.7%.

Since then CPI-trim has fallen 1.2 points to 1.9% and CPI-median 1.1 points to 2.0%, while CPI-common has moved only from 2.7% to 2.6%. The two measures that exclude or discount large price moves say underlying inflation is at target. The measure built to capture broad common pressure says it is still about six tenths above.

The Bank of Canada treats 2% as its target and 1% to 3% as its control range. Headline inflation at 3.0% sits at the top of that range, while CPI-trim at 1.9% sits just under the midpoint.

The swing in headline inflation, from 1.8% in February to 3.2% in May, was a 1.4-point move while CPI-trim fell 0.3 points over the same stretch. That pattern is consistent with a shock concentrated in a few components, such as energy, where WTI crude settled at $97.97 on Thursday, rather than a broad acceleration in prices.

The Labour Report Sharpens the Policy Choice

The 68,000 job loss in September was led by the public sector, where employment fell 70,000, the fourth straight monthly decline, with educational services down 35,000. That exceeds the entire net decline. Manufacturing lost 13,000 jobs in the first full month after new US tariffs took effect, and average hourly wages rose 2.3% from a year earlier, up from 2.0% in August.

Economists read the report differently. Andrew Grantham of CIBC said the weak data likely reflects data volatility, and CIBC expects the Bank to hold at its two remaining meetings this year. Claire Fan of RBC called monthly employment counts notoriously volatile. Douglas Porter of BMO described the appropriate stance as watchful waiting, with employment still up 0.5% from a year ago.

Royce Mendes of Desjardins said higher energy prices could force tightening soon, and Thomas Ryan of Capital Economics expects the Bank to raise its rate to 2.75%, the midpoint of a neutral range of 2.25% to 3.25%, then stop. LSEG pricing reported by Reuters put October hike odds at about 25%, down from roughly 40%, and TD Economics put December odds at 88%.

The Transmission to the Dollar and to Variable Rates

The Federal Reserve raised its policy rate on September 16 to a range of 3.75% to 4.00%, which puts the gap to the Bank of Canada rate of 2.25% at 1.50 to 1.75 percentage points. The Canadian dollar traded at 1.4275 per US dollar, or 70.05 US cents, its weakest level since April 2025, according to Reuters.

A weaker dollar raises the Canadian price of imported goods, which is one channel back into headline inflation. The Federal Open Market Committee meets October 27 and 28, the day before the Bank of Canada decision, so the Bank will have the Fed outcome in hand.

A Bank of Canada increase would move prime and variable-rate mortgage payments with it, while fixed rates follow bond yields, which also respond to US yields. On Monday the questions are whether headline inflation falls back from 3.0%, holds or rises, and whether CPI-trim and CPI-median stay at or below 2.0%. A stable core supports the hold that TD, CIBC and BMO describe, and a rising core would push the December odds higher.
