Canadians love their monopolies full stop. It's a cultural issue where each sector has its handful of heavyweights, of which you have a choice of 1 or 2 to use locally, and even if there is a third option most Canadians just won't consider it.

Comparatively, the US has thousands of small banks & credit unions, and tons of small and midsize ISPs that provide a 3rd or 4th option in areas like MDUs where they can make a go of it.
