Today's packet of coupons in my (Canada Post) mail box included two that seem to indicate that Shaw is loosening up on their "nobody but us" use of the Shaw cable connection to my home.
Distributel.ca is selling what they call "Cable Internet" (they also offer "DSL Internet"), so I am assuming they are running on Shaw's cable network. Their selling point is unlimited downloads. You can also bundle with home phone service, which I assume is also on the Shaw cable network.
Revtel (1010738.ca) advertises that they can now offer "dial around" long distance for Shaw Home Phone customers, not just the traditional telcos. Their selling point is lower rates, but the fine print reveals the usual "minimum charge per call".
The CRTC ordered cable companies to allow access to their networks back in the 1990s, but only one did at that time, some little guy in Tillsonburg, Ontario, I think it was.
