Transit through Canada YUL/YYZ
I’m looking at options to jumpseat or ZED fare to Europe from the US. I hold an EU passport and a green card for the US. Since I can’t enter Canada as a foreigner I would like to know if there’s a possibility to stay in the transit area without entering Canada. The idea is to arrive from an US flight and to leave with another international flight to Europe. To avoid picking up and rechecking bags I would travel with carry on only. So my question is specifically for YYZ or YUL. Will I be able to just transfer through one of those airports without having to deal with immigrations? Or is there a procedure that immigrations lets me leave the country right away? Thanks for any input!
