Our vendor waitlist is now open. Please find the application form below. Vendors on the waitlist will be contacted if spots become available throughout the season.

The Aftermarket

We’re two siblings from Durham Region building a curated night market in Downtown Oshawa. The Aftermarket connects the before and after of a night out, while creating a platform for independent businesses and emerging entrepreneurs to show up, test ideas, and grow. A place to stop in, stay a while, and experience something local. We prioritize original work, local talent, and drive traffic to surrounding downtown spots.

Who we're looking for

No experience required. Whether you’re just starting out, building a side project, or already established, we care about: quality, originality, and alignment with the vision. No resellers (unless curated, vintage, or antique). No mass-produced or AI-generated goods.

Why Saturday Nights?

Built for people with full-time jobs, side hustles, and early-stage businesses. Taps into the busiest, most energetic night in Downtown Oshawa.
