Every row is indexed to the last month complete before the first day in office ("from" marks a start that had to move because that period had no data, or because the period cut it); Levels are per cent changes, rates are differences in %; "per year" compounds levels and divides rates. Tenures with under 12 months, or under three observations, are left out. ¢ per litre, self-service · Statistics Canada, average retail prices (table 18-10-0001), regular unleaded, self-service · Canada data · as of Sep 2026.
