Investigation into COVID-19 vaccination attestation requirements established by the Treasury Board of Canada for employees of the core public administration

Treasury Board of Canada Secretariat

This investigation examined the COVID-19 vaccination attestation requirements for federal public servants. The OPC found that the collection of vaccination status was directly related to the employer's health and safety obligations. However, the Treasury Board of Canada Secretariat (TBS) contravened the Act by failing to update its index of personal information banks within the required timeframe. The OPC also assessed the necessity and proportionality of the measures, concluding they were justified given the pandemic context, though TBS's documentation and response during the investigation were found to be lacking.
