I'm with Bell, albeit in Ontario, and my account doesn't have any restrictions. I'm not sure what you are currently paying, but my monthly rate is comparable to the one I'd have to pay for cable internet.
If you don't have a land line, Bell has to offer you the service anyway, its a CRTC ruling. Call them up and ask about the 'dry loop' service. I'm not sure how much it costs, but I know they have to offer you internet service independent of whether or not you have their phone service.
