Just for future reference, the Lakeshore West train may be easier if you live on/near campus. You would take the 15 Aldershot/Burlington bus at the GO bus near Mary Keyes, to Aldershor or Burlington station, then take the train there all the way to union. Although it's slightly longer, I like the train route more cause you don't have to be in a crowded bus, especially if it's during rush hours. Oh, and the train's more comfortable
