Tech giants' ad tech dominance in Canada raises national security risks due to mass data collection and foreign exploitation threats.
A new report warns that tech giants like Google, Meta, and Amazon, which control over 90% of Canada’s online advertising market, pose serious national security risks due to their dominance in automated ad auctions that collect vast amounts of personal data.
These systems, operating in milliseconds, gather sensitive information including location, health, finances, and political views, enabling detailed profiling of individuals—especially government officials—making them vulnerable to surveillance, blackmail, or disinformation by foreign actors.
The report urges Canada to restrict data collection and break up the concentrated power of major tech firms, whose business models rely on ad tech control.
While Google denies anticompetitive behavior, legal challenges from Canada’s Competition Bureau and the U.S. Justice Department continue, highlighting concerns over inflated ad costs, reduced publisher revenues, and weakened market competition.
