Arts in the Annex

Check out this page for events that are happening in our outdoor tented space!

The “Annex” is a restored structure located on the grounds of the Alton Mill Art Centre. Historically it was the building used to store wool when the Art Centre was used as a knitting mill. With funds received from the Ontario Trillium Fund, we were able to purchase and install a tented roof over the Annex making it the perfect place to host outdoor events such as concerts, art shows, markets, weddings, etc!


Inviting all artists and artisans to apply for a one-day-only market under the tented roof at the Alton Mill Arts Centre taking place during our annual Fall Festival Juried Art Show and Sale.

We acknowledge that the land on which we gather, and on which the Region of Peel operates, is part of the Treaty Lands and Territory of the Mississaugas of the Credit. For thousands of years, Indigenous peoples inhabited and cared for this land. In particular we acknowledge the territory of the Ani-shinabek, Huron-Wendat, Haudenosaunee and Ojibway/Chippewa peoples; the land that is home to the Metis; and most recently, the territory of the Mississaugas of the Credit First Nation who are direct descendants of the Mississaugas of the Credit.

We are grateful to have the opportunity to work on this land, and by doing so, give our respect to its first inhabitants.
