Fi Series 3+ Smart Dog Tracker Collar (Gray, Medium)
Excellent escape-artist hardware wrapped around a subscription and a coverage question Canadian buyers have to answer before they click buy.
Best for: Owners of fence-jumpers, sighthounds and door-dashers who live in strong LTE-M coverage areas and are fine paying an annual data fee on top of the collar.

The best-value LTE dog tracker you can actually buy in Canada, as long as you accept that the $76 hardware is a doorway to a monthly bill.
Best for: Owners of escape-prone dogs over about 4 kg (8.8 lb), rural and off-leash households, and anyone who wants nationwide live tracking rather than 60-metre Bluetooth range.
