Hi everyone, I have a general question about runways. In Montreal for
example (CYUL) or anywhere else. What would be a factor making planes
land on Rwy 24L vs landing on 24R. I understand that prevailing winds
play a role in determining if its 24L or 06L, but I cant figure how
they decide to use left or right.

thanks again!

Other folk's answers seem to be assuming commercial IFR traffic. In
my experience in general aviation VFR, the assignment is based in part
on where you are when you first call in. Based on that, you'll get
assigned the base or downwind entry that involves the least
maneuvering.

(Sometimes, as is the case at Palo Alto, in California, one runway may
have traffic patterns on each side. Which one you're assigned depends
on where you're coming from.)

For practicing touch and goes, instructors with lower-time primary
students may request the longer runway.
