Re: VOIP providers in Ontario? It depends on your usage whether you should go with flat rate providers like Vonage, Primus, TekSavvy or pay as you go providers like voip.ms for FPL (long distance isn't free with them). Most people probably keep in contact with their mobile devices, email and skype so voice calling is dropping in usage which is why voip.ms and FPL are popular with people who don't use the phone as much anymore.
But in my parents household, my mother uses the phone heavily, to talk to her friends in the city, Toronto, the US, and a few international countries. Setting them up with unlimited usage via Vonage was the better value. A credit card gets billed monthly for the same amount without needing to worry about buying credits.
