Well, what did we get for ignoring structure over the past 40 years? The C.D. Howe Institute put out a piece saying that of the eight contested mergers in Canadian history, seven resulted in market shares of over 60% and four of them resulted in literal or near monopolies. In the past 40 years, we've ignored structure, and it has cost us. It has led to consolidation across the economy.
Structure is not a perfect measure, but it's one way we create a system that has a higher likelihood of protecting Canadians, and I think we need to learn from our peers, as well as our own history, to guide the future on that.
