Where can I buy baby girl newborn fall and winter jacket in Mississauga/Toronto in summer?

Hi everyone! I will be an aunt soon to my niece. The big problem is that I need to get winter and fall baby girl jackets (clothes) now, in summer time, and I am not really sure where I can find them at this season. I don`t like all that online shopping stuff, prefer to see something in real before buying. Please give me advise of place in Mississauga or Toronto where I would be able to buy. Thank you in advance for your advise.
