I grew up in Mississauga and always frequented this mall when commuting to school or work. Square One is continually improving their appearance through gradual renovations and a lot of higher end stores being added. The food court looks similar to the one at Eaton Centre giving you more of a modern feel and an increase in seating space.
I love this mall because it has all the stores I need in all in one place. It never gets super crowded unlike some other malls. There tons of parking and restaurants surrounding the mall. It is accessible exiting off hwy 403 Hurontario and also has many bus routes that take you directly here.
It is known to be the biggest mall in Ontario and will continue to expand with their success.
