LTE band b4 is used in Canada the link you provided for the phone shows global bands in the high lights of the phone so it should work as for the list of phones that work with public mobile those are the ones guaranteed to work not the only ones. If you check this link you can see what carriers use band b4 https://www.frequencycheck.com/bands/lte-band-4-aws-1
hi @marti713 while the phone is VoLTE capable, PM has its own VoLTE shortlist and only those phones (and their later generations ) on the list can access PM's VoLTE
It seems that it will work in Canada but I would suggest you also look the Moto (Motorola) G Play or the Samsung A03 for around the same price with warranty coverage in Canada.
