There is also a fair size one in Square One Mississauga. There are several ways to get there, all involving 401 East from Kitchener.
1) 401 East, exit at Hurontario and go south. The mall will be on your right hand side right after you pass over Hwy 403.
2) 401 East, If you prefer staying on the larger highways, instead of exiting at Hurontario, you can exit on 403 South, and again exit at Hurontario. This time you will be right by the mall. This route means you have a little back-tracking to do, but really only by about 1 city block, and depending on traffic, can sometimes be faster.
3) If you dont mind the toll fees, 401 East, exit at 407 south, to 403, take 403 to Toronto (East I believe, but all directions are strange here just follow Toronto sign) and exit at Hurontario again right by the mall.
The
Disney store is in the center of the mall, lower level by the food court.
Hope this helps!
