There's weird things though because they intentionally strip the Canadian language and region options out of AOSP and that causes some odd behaviour. Whenever I switch from my home towers to the ones around Nanaimo I get this odd message saying "Region changed to US, rebooting." And then the phone reboots.

A couple of times its gone into a complete bootloop and required reflashing because of this.

Also you have to use Australian English as the closest Canadian English.

At least, that's the e/OS experience on Fairphone 6. Still waiting for a release for postmarket
