This line from Rod Sims, former chair of the Australian Competition and Consumer Commission: Airports in large countries that rely on air travel, like Canada and Australia, operate as near monopolies if there aren't reasonable, nearby alternatives for flights.
Airports should only be privatized in places where there are potential reasonable alternatives: Toronto, Ottawa, and Montreal (once Alto is operational).
Flying is already a pretty exclusive middle/upper-middle class and above travel option. Like driving in this city, there are not great options (although I think a bus is coming) but to drive if someone needs to get to Edmonton, Regina or Saskatoon. The windfall from the sale will be good but then you potentially make flying a even more out of reach option. You could argue that then they will just lower prices but I think flying is one of those things that people that can have a very high tolerance to just pay for. Prices didn't seem to come down after airlines made back their covid loses and now, I'm sure they've reached a new floor after this fuel crisis.
As is pointed out in the article, regulation could be an answer but that has its pitfalls too.
In theory once you build up Alto and maybe even Alto-west here in Alberta between Calgary and Edmonton, you could sell that off and regulate it as well. Then why stop there, sell off the QE2 and then we really let the free market decide the best way to travel between Calgary and Edmonton.
