With WestJet, it's easy to explore everything that makes Toronto great. You’ll find so much more than the Toronto Stock Exchange here; in fact, you'll discover a world-class theatre district, multicultural neighbourhoods, historical sites and some of the highest grossing major league sports teams. We could list the city's virtues all day long — but it's better to visit and see for yourself.
Your trip to Ontario's most vibrant and diverse destination starts when you book your cheap flight. We know the CN Tower, the Hockey Hall of Fame and Canada’s Wonderland are amongst the things you can’t wait to see, which is why at WestJet, we’re dedicated to getting you from St. Louis to Toronto.
