I have been to the Simons in Montreal a few times and never really liked it much. Not my style. Surprisingly, I like this one at Sq1 better. Props to whoever the merchandise buyer is for this location.
It is a mix of brands here. I've seen a $10 skirt and $20 dress on one end of the store and on another, I would see Comme des Garcons PLAY and other higher end brands. Also, spotted a bloggers brand here called Cupcakes and Cashmere. The person was a stylist I think for Lauren Conrad.
Personally, I recommend checking out the accessories section, it's not huge but they have some unique brands. I had to do a double take when I saw Quay sunglasses! Been looking for this brand for ages and it's mostly available only online.
The main floor is women's, swimwear, active wear and home (bedding/kitchen/pillows). The second floor is mens, customer service, and a cafe with a patio overlooking mall entrance. Good for people watching. Lol. I also spotted portapotty style change rooms for guys in the far end of the store. Kinda funny.
