The large Canadian Telcos (until maybe in the near future) are actually regulated quite heavily to provide sub-services at competitive rates to competitors along their vertical integration. So you can spin up an ISP in Canada, buy capacity off Telus, and provide a decently priced competing product assuming you can undercut their overhead & admin costs.
