The Pickering flea market is definitely not the best market out there as it does need a bit of updating here and there, but as far as weekend markets go, this one's atleast consistent and gives you a nice variety of stalls to see. Could there be more options? Perhaps. But what do you expect from a flea market?
There's an entire antique section that you can visit and go to bidding wars for or a sort of one stop shop for all your beauty, cosmetics, home needs at super discounted over stock prices. Then you got a nice little for court with a few good options and a nice selection of privately owned stalls where you can find anything from clothes to games to hardware and coins, etc.
Place hasn't changed much in the past few years and aside from a few structural updates, I don't really think it needs to.
Ample parking and easy access. It's a nice market to kill an hour or two :)
