Welcome to the community!
Do you know which version you have? According to the website, these are specifications for the various versions:
According to those specifications, all of those versions 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.
Hope this helps 😀
