The 3.1 percent rate did not bring prices back
No. The drop in Canada’s inflation rate from 8.1 percent in June 2022 to 3.1 percent in September 2026 did not mean prices fell back. The Bank of Canada’s consumer price index table, checked October 21, 2026, shows the total CPI at 152.9 in June 2022 and at 170.0 in September 2026. The later rate means the national basket was rising more slowly than in the year to June 2022. It does not mean the basket cost less than it did then.
Disinflation is a smaller inflation rate. A fall in the price level would be deflation, visible as a lower index rather than as a smaller positive percentage. September 2026’s 3.1 percent is still an increase from a year earlier, and the index printed beside it is higher than in June 2022.
This is a historical comparison, not a forecast and not a statement about any one household’s receipts. In the months shown, from May 2014 through September 2026, 8.1 percent is the highest 12-month total CPI rate on the table. September 2026 is the latest month available at the October 21, 2026 check. The two dates are 51 months apart, so the contrast should not be treated as news that prices changed on the day the table was checked.
A 12-month rate is not the whole gap
The 8.1 and 3.1 figures are the percentage change over the past 12 months. Each compares the total CPI with the same month one year earlier. Neither measures the change from June 2022 to September 2026.
The index levels line up with those printed rates after rounding to one decimal. June 2021 was 141.4. The rise to 152.9 is 11.5 points, and 11.5 divided by 141.4 is about 0.0813, which rounds to 8.1 percent. September 2025 was 164.9. The rise to 170.0 is 5.1 points, and 5.1 divided by 164.9 is about 0.0309, which rounds to 3.1 percent. That check uses only this table. It is not a separate official release.
A low rate can therefore sit on earlier increases. It can also tick up. The 12-month total CPI rate was 2.8 percent in June 2026, 3.0 percent in July and August 2026, and 3.1 percent in September 2026. Slower inflation than in June 2022 is not a rate that is still falling every month.
The index is not a dollar amount: the table states no base period and does not convert 152.9 or 170.0 into groceries, rent, or fuel.
From 152.9 to 170.0 is an 11.18 percent higher index
The level change is a different calculation, and it should be labeled as one. Subtracting 152.9 from 170.0 leaves 17.1 index points. Dividing 17.1 by 152.9 gives approximately 0.1118, or 11.18 percent, which is 11.2 percent when rounded to one decimal. The only assumptions are that the first total-CPI number in each row is the index and that the table does not record a change in the index base between these rows. No rebasing is mentioned on the page.
That 11.18 percent covers 51 months, not one year. Four years from June 2022 to June 2026 account for 48 months, and September adds three. It cannot be compared directly with 8.1 or 3.1, because those rates each cover 12 months.
The rise was not perfectly smooth. The index dipped to 152.6 in August 2022 and 152.7 in September 2022, then later moved above 152.9. It also eased from 169.9 in July 2026 to 169.8 in August 2026. September 2026, at 170.0, was still higher than June 2022. Along the way, June readings were 157.2 in 2023, 161.4 in 2024, 164.4 in 2025, and 169.0 in 2026, with 12-month rates of 2.8, 2.7, 1.9, and 2.8 percent.
Core rates also slowed, and they are still rates
Other columns are 12-month rates, not price levels. In June 2022, CPI-trim was 5.7 percent, CPI-median 5.2, CPI-common 5.5, CPIX 6.2, CPI-XFET 5.3, and CPIW 6.4. In September 2026 those readings were 1.8, 1.9, 2.4, 2.2, 2.1, and 2.5 percent. The page heading refers to preferred core measures and marks CPI-trim and CPI-median as seasonally adjusted. A lower rate means slower increase over 12 months, not a return to the June 2022 index. Separate index levels for these measures are not shown, and food, rent, and fuel are not split out.
What a household can and cannot conclude
A lower headline rate is not a rebate of the earlier increase. At 170.0, the September 2026 basket index was higher than June 2022’s 152.9. Unchanged dollar income would command less of that basket. That follows from the index; the table says nothing about pay, pensions, or benefits. Nor does 3.1 percent tell a firm to restore 2022 list prices. It says only that the total basket was 3.1 percent higher than in September 2025.
Food, rent, and fuel are not in the table, so their prices cannot be inferred. The index is not a dollar cost and cannot rank Canada against another country. Some cells are marked "R," including 169.4 next to the August 2026 index and a September 2025 core rate. The 170.0 and 3.1 readings for September 2026 are not marked revised. They are observations, not forecasts, though later revisions remain possible.
Watch the next rows on this table: whether the index stays above 170.0, whether the 12-month rate stays near 3.1 percent, and whether revision marks appear. That is the evidence for whether level and rate still diverge. It will not name which bills changed.
