I love Yorkdale. One of the best in Canada for sure.
If your into high end designer goods (Louis Vuitton, HOLT, BURBERRY, COACH, MICHEAL KORS, POTTERY BARN etc) and with a mix of inexpensive shops (COSTA BLANCA, GAP, VICTORIA SECRET, CHAMPS, H&M, AMERICAN APPAREL etc).. THIS IS THE PLACE TO VISIT. They certainly have (if not) almost everything you like.
Am only giving this 4 stars because am a little disappointed about the size of their food court which is located at the upper level. Not much selections to choose from and you have no place to sit if you come on a busy weekend. In my opinion that area needs to be maximize for more seating. But if you prefer a non-food court style.. there are some restaurants you can swing by inside the mall.
