Just a note, I don’t think there are many Canadian small ISPs which buy internet access wholesale in order to resell it. There are many who lease “last-mile” connectivity from both as Bell, Rogers and Co as owners of the copper they are required to provide that, but it’s not in their interest to sell wholesale internet access to a competitor. You will hit an IP network device of your own ISP first and never be on on an internet routable segment of Bell/Rogers so its unlikely they would be able to block other kinds of encapsulated traffic (assuming the agreement even allows that, which also seems unlikely). If you are a small ISP, you have much better options for transit than Bell or Rogers at that point.
