Doesn't Virgin use Bell's network for both cell and internet?
And I believe TekSavvy piggybacks on other internet carriers networks, like Rogers, Bell or Telus, depending on where they offer their service, except in rural parts of Ontario...
I do wonder if we could ever get serious competition in Canada. Our market in small compared to many other nations, but we take it up the ass for how expensive it is and how poor our service is. I remember about a decade ago when I think it was Verizon was thinking about moving into Canada, and they got massive pushback from the big three (shocking, I know). But something needs to be done.
