The only risk I could see would be on the way back to YUL, where if you travel during rush hour there might be a risk of not being able to get a seat on the bus that many stops into the route.
I took the bus today, and the stop was across the intersection from the hotel. However, I was not pleased with the ride - the lineup at the airport was long and I had to wait in line until the next bus pulled up, and then it was full and I was fortunate to have found a seat. About half of the passengers left at the first stop, though.
