Yes Toronto does need the PanAms. Canada has shown that it is capable of hosting Winter Games and Pan Am games recently, however Toronto 2015 will be the largest multi-sport event in Canadian history in terms of events and athletes, bigger than 1976 in Montreal. Canada, and especially Toronto, has not yet been tested like they will be tested in 2015. Obviously Toronto and Canada in general can sustain an event like the Olympics, but these games further cement that claim and give the country a well needed dry run for an Olympic Games.
