According to the Canadian website, these are the specifications for that phone:
Judging by those specifications, that phone should have all of the compatible bands/frequencies. You can verify the compatible bands/frequencies here. While the phone should work on the networks, you should note that since Fido does not offer OnePlus devices, it's unlikely certain features (ie voLTE and/or Wifi-calling) will work with that device. You should also note that other versions of that device may not have the same band/frequency specifications.
Hope this helps 😀
