Can I make a 4 hours connection at YUL on an international flight?
4 hours clears the 90-minute international minimum connection time at Montreal International Dorval, but you should still head directly to your gate. All piers connect via a single central terminal building, so there is no train or shuttle — everything is done on foot along connected concourses. Passengers arriving internationally who are connecting to a US-bound flight must exit the sterile zone, clear Canadian customs, then proceed to US preclearance and go through a full second security and immigration screening before re-entering the sterile area.

We recommend at least 1 hour 15 min for a comfortable connection at Montreal International Dorval. This gives you enough buffer for security (typically 20 minutes) and transit between terminals (up to 20 minutes).
What happens if I miss my connection at YUL?
Air Canada and most partner airlines have transfer desks near the international and transborder piers where staff can rebook missed connections; if you clear US preclearance and miss your flight, you'll need to work with airline staff on the US side since you're technically already through US immigration.
