Product & Service Introduction:
===============================
Canadianisp.ca - Is a wholly owned project of Marc Bissonnette / InternAlysis.
It was originally created as a joint venture with Bob Carrick of Carrick Solutions, with sole ownership
transferring to Marc Bissonnette on February 16th, 2004. Canadianisp.ca is the only website that allows
you to search for an Internet service provider (Dial-up, ISDN, DSL, Cable, Satellite, Point to Point, Wireless
and Voice Over IP (VoIP) anywhere in Canada. Customers can post reviews, and ISPs submit their own services.
All for free. CanadianISP is also one of the most accurate and most up-to-date ISP lists on the net. There are
many ISP lists out there, but the vast majority of them (as far as we have seen and we last searched and looked
in April of 2011) are out of date, listing companies no longer in business, no longer providing connectivity
or simply pages of ads with no relevance to the users search parameters.
ISPs can submit and edit / update their own services at all times, free of charge.
