In response to growing concerns about foreign interference, the Canadian government has proposed new legislation to combat this threat. The Foreign Influence Transparency and Accountability Act was proposed in May 2024 and must undergo parliamentary review before it is passed. Until then, the act will be scrutinized against similar legislation among Canada’s allies in the Five Eyes security alliance (Australia, the United Kingdom and the United States — New Zealand has developed its own approach). This policy brief looks at how these countries have implemented foreign influence transparency registries and what Canada can learn from them to create its own model.
