Venice, Telluride (in Colorado) and Toronto all take place within a few days of each other in late August and September, and compete to host the very best movies.
Even though it doesn't get all of the major films which play at the other events, Toronto is a reliable Oscar predictor.
For the last decade, the winner of the festival's People's Choice Award, voted for by filmgoers, has consistently landed a best picture nomination, with a couple of films - Green Book and Nomadland - going on to win.
