Government. Not liberals or conservatives, but the government as a whole. Canada has had many years where both liberal and conservatives were in charge, and nothing changed.

Canada doesn't allow competition. We have 3 main internet providers, 3 main phone plan providers, like 2 grocery store chains, a couple airlines, etc.

When other companies attempt to come in to break up monopolies, they lobby, and get them shut down.

I mean where are we going to go? America isn't really an alternative, as much as Americans think it is. Our healthcare, gun laws, etc are things that make Canada really good. We could move to some European or Scandinavian country, but that's not as easy as it sounds, especially when you need to learn a new language, get accepted, move your entire life, and live in such a different culture.

So people in Canada just accept it. Maybe one day monopolies will be broken up, but there are no parties that are going to do that now. Left or right leaning.
