Headline inflation in Canada was 3.0% in August, matching July, while the Bank of Canada core measures stood at 1.9% for CPI-trim, 2.0% for CPI-median and 2.6% for CPI-common, according to Bank of Canada data. The gap between the two is the policy question. Statistics Canada releases the September Labour Force Survey at 8:30 a.m. ET today, 19 days before the Bank of Canada next decision on October 28.
The Bank attributed the headline reading mostly to gasoline when it held the overnight rate at 2.25% on September 2. Excluding gasoline, inflation was 2.2%, and measures of core inflation remained close to 2% in July. The Bank also said upside risks to its inflation forecast have increased, and that the longer high oil prices and elevated refinery margins persist, the greater the risk of spillover to other prices.
A Gasoline Story That Has Not Yet Become a Core Story
The sequence in the data matters. In July 2025, headline CPI was 1.7% while CPI-trim was 3.1% and CPI-median 3.0%, so core was running well above headline. By August 2026 the order had reversed. CPI-trim has fallen 1.2 percentage points in 13 months to 1.9%, while headline has risen 1.3 points to 3.0%, with most of the increase coming after the Hormuz conflict began on February 28: headline was 1.8% in February and 3.2% in May.
Headline CPI has risen 1.3 percentage points since July 2025 while CPI-trim has fallen 1.2, and the crossover came in the months after the Hormuz conflict began, which is the profile of an energy price shock and not of broad price pressure.
CPI-trim, CPI-median and CPI-common are the Bank of Canada core measures, shown as year-over-year changes. The dashed green line marks the 2% inflation target, and September data are due later this month.
CPI-common is the exception. At 2.6% it has stayed between 2.5% and 2.9% for 14 months, which is the strongest argument that underlying pressure has not faded as fully as the other two measures suggest.
Why the Bond Market Is Pricing a Different Path
The Government of Canada two-year yield was 3.25% on October 8, 1.00 percentage point above the 2.25% overnight rate, according to Trading Economics. The three-month T-bill yield was 2.39% on October 7, according to the Bank of Canada. The distance between the two says the bond market expects the policy rate to rise within the two-year horizon, even though core inflation is near target.
Part of that pressure is external. The Federal Reserve raised its target range to 3.75% to 4.00% on September 16, according to MUFG Research, which puts the lower bound 1.50 percentage points above the Bank of Canada rate. Before the August CPI release, TIO Markets reported, markets priced roughly a 58% chance of an October increase, a probability that eased after the data.
What the Labour Force Survey Can Change Today
The Bank of Canada described labour demand as subdued on September 2, with indicators pointing to continued excess supply. August data fit that description: employment fell by 41,700 and the unemployment rate held at 6.4% only because participation fell 0.1 point to 65.0%. TIO Markets compiles a consensus for September of a 6.5% unemployment rate and an employment gain of roughly 7,000, an estimate it describes as soft.
A reading at or above 6.5% would reinforce the excess-supply language and the case for holding at 2.25% on October 28. A decline in unemployment alongside solid job gains would strengthen the argument that the Bank must weigh the spillover risk it flagged. Second quarter GDP growth of 3.3%, following a very weak first quarter, shows the recovery is broadening, which makes the labour market the data point where the two readings of the economy diverge.
The Transmission to Mortgage Rates
Fixed mortgage rates follow the five-year Government of Canada yield, which was 3.60% on October 8, not the overnight rate. Variable-rate borrowers are exposed to the policy rate, which TIO Markets reports has been unchanged at 2.25% since October 2025. A five-year fixed term renewing this fall is priced off 3.60% plus the lender spread, 1.35 percentage points above the overnight rate, so the bond market path reaches households before the Bank moves.
Five-year fixed terms signed in 2021 are renewing now and reprice against that benchmark. The September CPI, due later this month, is the second data point before the October 28 decision, and it will show whether the gasoline effect has reached the measures the Bank watches most closely.
