There are few Value Villages in Toronto that aren't picked over completely, but the one by Queen and Carlaw is usually a good bet for some hidden gems. They have a large selection of kids stuff and accessories as well, bigger than most. It's right on the street car line and they don't completely over price everything although they are wise to the labels. Ralph Lauren will always be more expensive than a generic brand, even if it's not in the best condition, but the staff are super nice and informative (like they know where to direct you rather than being all glazed over) and I've never gone in without finding something that was worth making the trek for.
