I have a flight coming up from the US to Montreal (US1-YUL). It was originally part of a longer itinerary, in which I lost interest. Now I want to return home instead (YUL-US2) on a separate itinerary. I will not have any checked luggage, just a backpack.
When I land in Montreal, will it be possible for me to stay in the secure area and avoid going through Canadian immigration and TSA?
Thanks in advance for any tips on how to proceed in this situation.
