Have you had a chance to view the link FidoVanessa provided? Unlike for your original post regarding EUMI 10 , it doesn't appear the EUMI 12 updates have been released for that device from Huawei Canada (see here).
Mobile providers can only offer updates which are released by the phone manufacturers. You might consider contacting Huawei Canada to see if they have any further information regarding that OS update for Canadian devices.
Hope this helps 😀
While Huawei has started rolling out the update to different regions they did not release any updates for the Canadian market as of yet.
Once they release the update for the Canadian market Fido will begin the update process. You can keep an eye on the OS Upgrade page here for release dates.
