In theory it should work on the network since it does appear to support the common frequencies used in Canada, but you'd probably need a tablet SIM for it. A phone SIM typically cannot be used in non-phone devices. Pretty sure Bell has the same rules / limitations. If the camera is going to be located in a rural area, some of those tower have different frequencies in use so in rare cases not all third party devices will work.

You'll want to talk to sales at either provider to see what your options are for a data only SIM card that is not going to be used in a phone.
