Tablet plans are data plans, just that the the telcos go through great pains to try to convince you otherwise. Best course of action is to go to a telco kiosk and ask for a tablet plan, and be coy about the device you will be using. Find another kiosk agent if the one you are dealing with will not play ball. Once activated, you can use any device you want, as long as it is carrier compatible, and/or unlocked.
Currently, til the end of the month, Fido sells a tablet plan for $15 for 1GB, $25 for 3GB, $35 for 5GB, and $10 a GB overage after that. There is a pretty good thread on it here

If you go with Telus, make sure you pick the right APN setting, because you will get raped in charges if you use the default Telus APN. I see no value to go with Telus, but it is a heads up.
