On the law enforcement side, as I was explaining before, being dominant is not a violation of the Competition Act. Even having a monopoly in Canada is not a violation; it's what you do with that. Is the dominant entity doing something to protect itself from having to face competition from its rivals?
Perhaps to be clear, just because there is not a violation of the Competition Act, that doesn't necessarily mean that a market is working well from a competition perspective. I think there are lots of markets where competition can be improved. Especially in an oligopoly-type setting, where you have concentration and high barriers to entry, it's sometimes the case that firms competing in that type of market structure don't need to violate the Competition Act in order to reach mutually beneficial outcomes.
