Hello timber777! I invite you to contact Vidéotron's Customer Service by phone if you haven't made the switch yet. All your questions will be answered and you will be able to complete the transfer of your mobility service.
I've been with Videotron in Ottawa (Kanata) for 4+ years and the service has been ok . Roaming might be iffy at times (Toronto for example). No eSIM if that matters to you. Good customer support - unlike the Big 3.
BTW... never had issues during the Robbers outage 😉
