Not sure how to re confirm, IRCC refer to this link, my tickets are booked, I have got a travel authorisation email from IRCC Based on workpermit so hopefull I will be okOn my CoPR it says 'If you leave Canada' without a permanent resident card, you will have to apply for a permanent resident travel document through a visa office. Otherwise, you will not be able to board a commercial vehicle(plane,train,bus or boat) to come back to Canada.' So my understanding is the border will let you in, but you will have difficulties to travel on a plane.
