Income and Financial Data of Individuals, Preliminary T1 Family File

Summary of changes

Activity on this program started: 1982

Reference period of change - 2022

Starting with 2022 income data, some components included total income are derived using other data sources to improve their precision. Caution should be taken when comparing variables related to total income of 2022 and onward to prior years' data. The new methodology does not impact the values of charitable donations; RRSP contributions; and wages, salaries and commissions but may have an impact on the statistics related to total income included in the tables produced with the preliminary T1 Family File.

In 2022, the Canada Workers Lockdown Benefit program was the only COVID-19-related program still in effect to financially support Canadiens. Nevertheless, several governmental programs offering COVID-19 government income support and benefits in 2020 and 2021 have paid financial support retroactively in 2022 and are thus included in total income. In 2022, all COVID-19 benefits have been included in total income under other government transfers.
