There's a Vaughan Juried Art Exhibition that we just discovered a pamphlet for. Open to anyone in the GTA, the deadline is March 14, 2008. The exhibit will be at the City Playhouse Theatre Lobby in Thornhill. Art is to be submitted as a JPEG on CD, and there's a $20 entry fee.
The pamphlet says that the City of Vaughan is starting a municipal art collection, and is using the show to scout out purchases.
There is a webpage about the exhibit, but you can also visit the studio to take a look at the pamphlet.
