I'm currently with Velcom (reseller like teksavvy) on a 6Mbps down/800kbps up aka pretty shit.
I hear their cable service, although officially 400GB bandwith, is actually unlimited as they have no way of monitoring it due to some technical reason (don't know how long this will last). Pretty sure this is the case with teksavvy cable as well. This was a few months ago so I'm not sure if it still applies.
Edit: hmmm looks like they have higher speed DSL (fibe) available as well, and also unlimited plans:
