In the March 30, 2023 comments submitted by Fasken[1] in response to the Government of Canada’s consultation and discussion paper[2] on the Future of Competition Policy in Canada (the “Discussion Paper”), significant concerns are raised about any amendments that move away from identifying anti-competitive conduct through evidence-based assessment of its effects and which would establish ex ante regulation to place blanket prohibitions on certain types of conduct by certain firms. In a paper recently published by the Competition Policy International[3], we examine the international and Canadian debate around ex ante regulations for Big Tech platform companies. The paper explores the need for and costs associated with ex ante regulation and concludes that pursuing such regulations at this time in Canada would be ill-advised.
