Yes, but without comfort. 120 minutes cover the 75-minute minimum required at Montréal (YUL) for an international connection. Across twenty thousand scenarios accounting for the inbound flight's delay distribution and the variability of the walk through the airport, 77% hold.

Do you need a visa to transit at Montréal (YUL)?
Potentially yes — and this is the airport's trap. There is NO airside transit at Montréal (YUL), Canada: every passenger clears immigration, collects their bags, re-checks them and passes security again, even to leave immediately for a third country. The country's entry conditions therefore apply in full, and without the required document the airline refuses boarding at departure. Special case: Montréal (YUL) hosts a US preclearance facility. A flight leaving it for the United States crosses the AMERICAN border before boarding — immigration, customs, second security screening. Without a valid ESTA or US visa you do not board, and you must allow roughly three quarters of an hour more.
At Montréal, airside connection does not exist. You clear immigration, collect your bags, re-check them and pass security again — even to leave immediately for a third country.
The official minimum connecting time database is an IATA commercial product. Our value for Montréal is a curated estimate, not contractual data. The figure that counts is your airline's.
With no prediction for this specific flight, the calculation uses an average delay distribution — roughly one flight in four late, most of them barely. A flight known for being punctual, or for the opposite, will depart from this figure.
This calculation assumes two international flights on a single ticket, with no terminal change and without knowing your passport. Specify them — that is where the verdict really changes.
