@sergiodj There are two train trips to Guelph leaving Union Station at 16:45 and 17:45, and a train to Bramalea with a bus connection to Guelph that leaves at 18:50. I don't know if there's a bus from the Guelph GO station to UofGuelph. There are some direct bus routes from Union Station to UofGuelph, but I don't know anything about them. GO will cost around $12 for a one-way trip. There are also Trentway Wagar or Canada Coach Lines buses leaving the Elizabeth St. bus station, but I don't know anything about them either. There's a chance the non-GO bus is cheaper than GO.
