I plan on flying from the US to Europe (Schengen) through Montreal airport (Trudeau Airport, YUL). The flights US-Montreal and Montreal-Europe are two different bookings. For the sake of simplicity, let's say I do not have any checked-in luggage.

According to the website of the airport, if I connect from USA towards a non-US international destination with automatic luggage transfer (or no checked-in luggage), I have to "go to the special international connections customs counter". But does that involve only customs or also immigration? I am particularly interested in knowing if my passport will be checked, if that makes sense.

So, do I have to go through some form of immigration/passport check when connecting in Montreal from the US to Europe?

  • Most likely it will be checked at least for ID purposes. I find that passport is checked for everything at the airport (Toronto). You should call the airport to confirm exactly what they will check, there is a 1-800 number at the bottom of their site

You and your passport and your boarding pass will be checked by Canadian border security, as they're the ones who run the "special international connections customs counter". They need to verify you are actually departing from YUL to the EU.

The airport's maps don't actually show the counter, but there's plenty of first-hand accounts about it.
