I think this is a likely guess.
You should have a very good chance of proceeding as described by @prkfsz.
Please take your time to do some reading:

I am very confident that you can recover the phone. (On the negative side I am not sure if you will have the difficulties found by USA users due to their carriers using exclusively VoLTE – a little more fully described in my first link.)
In choosing a stock ROM first you will want a Canada ROM, a little research will be necessary !!
You will want Android 10, that is Q. You will want the latest “Software revision” (SW REV) available, but not the very latest Security patch level (SPL) – an October or November 2022 release date would be fine. (I will omit further detail, please ask again when you did some research yourself.)
Good luck.
