One of the things I like to do on a Sunday morning is walk over to The Sunday Antique Market if we have nothing planned for the day. It's only a 15 minute walk from home (and I walk really slow) and fun to see what's around.
The Sunday Antique Market opens every Sunday, from 5am to 5pm at the North St. Lawrence Market building. It's always a good idea to go early if you have something specific in mind & vendors also tend to start closing their booths around 4pm. There are more vendors during warm weathers as well since a lot of them spread through outside the building. The best parking space is located south of the St. Lawrence south building but it's pricier than the one on 2 Church St. Parking can be a pain though so walking or TTC is much preferred.
Sorry for the lack of pictures- the booth owners were giving me the look whenever I lifted by camera.
The Sunday Market has smaller items for your home and not a lot of large furnitures compared to other antique markets. (But for someone who lives in a condo in downtown Toronto, the furnitures are too big anyway) There's always someone with the ever popular vintage wooden crates, mason jars and books & I love digging through their vintage accessory booths or vintage teacups. Located in downtown Toronto and opening every Sunday, it's also the most accessible market for me at the moment.
A few things I've picked up at The Sunday Market so far are:
A Cathrineholm lotus pot without a lid for $5
A vintage double picture frame for $5 that I used for our wedding
An old chest for $60 (I had to haggle for this one though)
Yes, someone else's trash can definitely be my treasure!
