I have a different take on this, and do agree with the ISP's in many ways.
Here is an article about it on CBC:

I think the problem is that the ISP's will make it a cash grab and screw everyone, but in reality they should apply the fees to the abusers only.
If the ISP's were smart they would provide packages. If you are a small user, surfing the occasional website and doing email... Then no change or even better a lower price, but if you use Netflix for 5 hours a night, download tonnes of music or whatever, then you pick a higher usage package, if you need more bandwidth then again you pay more. I see no problem with that, based on that is the major cost to all ISP's, Hosting companies and so on...
Lets see what happens, but most likely as I already stated, the ISP will take advantage of the basic usage and gouge them some extra cash.
