Investigation into the collection and use of de-identified mobility data in the course of the COVID-19 pandemic

This investigation examined whether mobility data collected by the Public Health Agency of Canada (PHAC) during the COVID-19 pandemic contained personal information as defined under the Privacy Act. The investigation found that the de-identification techniques and safeguards against re-identification implemented by PHAC and its data providers reduced the risk of identifying individuals below the "serious possibility" threshold. Consequently, the complaints were deemed not well-founded, as PHAC did not contravene the Privacy Act.

• Whether the mobility data collected constituted personal information under the Privacy Act.
• The adequacy of de-identification and aggregation techniques to prevent re-identification.
• Whether access to data within a provider's system constitutes collection under the Act.
• The need for transparency regarding the use of de-identified data.
