Square One is one of Canada's largest shopping malls — over 360 stores spread over two storeys, including a Hudson's Bay, a Holt Renfrew, a Saks Fifth Avenue, a David's Tea on every other corner, and a vast food court that mirrors the city's diversity better than any guidebook. The mall acts as Mississauga's de facto downtown.
If you have an hour to kill before a flight at Pearson, the express bus connection from the airport runs straight here.
