I tried to do this and it was such a hassle that i gave up and went with rogers.
What they will tell you is that it is simply not possible at all. What you should ask for is "zero-rated" internet. They will charge you internet and fibeTV for the first month and then you have to call in and cancel the internet portion. It seems sketchy but they will do it with alot of persistence. I couldn't deal with them though...
