Destination guide
Toronto: North America's most multicultural city
Toronto is a short hop from the Northeast and Midwest, with Air Canada, WestJet and every US legacy carrier competing on fares. The CN Tower, the Islands, Kensington Market and neighborhoods from Greektown to Little Italy make it a rich city break.
Best time to visit: May–September is warm with festivals nearly every weekend (TIFF in September). Late spring and early fall have the best value; winter is cold but hotels are cheap.
