Just a quick plug for the little farmers market in my neighbourhood.
Regent Park Farmers Market
585 Dundas Street East
Wednesdays 3:30 pm - 7:30 pm
I went last night and it wasn't huge, maybe 10 - 15 vendors but I did get some yummy food:
The Smoke Bloke: Delicate, and delicious Smoked Salmon
St Johns Bakery: Awesome French Sourdough
and some great Arugula from an organic farmer.
So it's probably not a 'destination' market that you will travel far and wide for, but if you are in the area it's worth checking out.
