This is largely true. Lynx didn't fail because they wanted to make too much profits. US low cost carriers don't fly to Canada because of the landing fees. I think this would be a bad idea. We have a pretty weak aviation sector, Westjet/Porter is private, and Air Canada stock performance is very weak, prime for a foreign takeover. Fares may lower in the short run, but it'd be a pretty significant security risk if the US or China owned all of our airline market, and that's basically the only method of travel between our largest cities.
