I left Videotron recently for Fibe, I was concerned when I made the move because I was coming from years of 60 meg net and moving to 16+. I generally get full speed down on the Fibe line, sometimes it moves to 18 megs while not watching tv, but I've made the move over with no real issues. With Bell Fibe I've got nearly 5megs up and 210GB on my cap, adding extra bandwidth it very cheap with Bell.
On top of that, if for some reason I got over the 210GB I'll only get billed up to a maximum amount before the overages cap themselves, with my last ISP, there was no billing limit. And the internet cost a hell of a lot more. $82.95/mo +3x $12.50 data packages = $120.45 before taxes.
My current Bell internet bill is Total (before taxes) $53.72 Granted there's a $10 discount on that.
I also find that peering in terms of North America and into the EU is stronger with Bell then it was with Videotron, although the peering within Canada isn't quite as strong ie. nearly anything from Montreal to Toronto goes via New York.
I'm just rolling over 8 weeks with FibeTV/Internet, yesterday I downloaded some updates from steam, they flew in at 28megabits, with Videotron they would have hit 55-60, but fairly, I'll wait the extra couple of minutes for the savings of $50+/mo.
2 nights ago my TV system was in full use, I had 3 HD streams recording, so much that I had to finish watching the hockey game on an SD stream, I ran a speed test and I was still sitting at 17 megs down and 4.8 up.
