As the 2025 federal election passes the midway point, it is increasingly apparent that the federal political parties are not only battling for votes, but also for data. Canadians may not see it but political parties are data machines anxious to collect and use as much data about potential supporters as possible. Sara Bannerman is the Canada Research Chair in Communications Policy and Governance at McMaster University. She has been examining the privacy concerns with Canadian political parties for years, highlighting the disconnect between the expectations of Canadians and the reality on the ground. She joins the Law Bytes podcast to discuss Canadian political party privacy – or lack thereof – and explains the role that data plays in the modern political party machinery.
