Updated basket weights for the goods and services in the Consumer Price Index (CPI), representing consumer spending patterns in 2020, are now available. The updated weights are based on data from the 2020 national Household Final Consumption Expenditure (HFCE), the Survey of Household Spending and the provincial HFCE series. Alternative data sources for the 2020 reference year were also used to account for pandemic-related shifts in consumer spending at more detailed geographic and CPI product group levels.

These updated weights will be incorporated into the June 2021 CPI, which will be released on July 28, 2021. They will replace the previous weights, which were based on 2017 purchasing patterns.

The weight reference period for the new basket is 2020. The index base period for the all-items CPI remains 2002=100.
