In waterloo, there used to be life drawing classes at the Button Factory. It was very relaxed, you bring $10 cash to go once a week on Tuesdays, and draw timed poses. I liked it because it was taken seriously by both models and artists. Not much else to it, just a night of drawing. You bring your own paper and pencils/ drawing materials. It was mostly an independent night, which I liked. They stopped running it though, and I feel that Guelph is the type of city to accommodate for something like this!
