I have a cabinet-maker contact in Kitchener-Waterloo that sometimes gets me some inexpensive sheet goods for my personal furniture projects.
I'm not affiliated in any way but wanted to pass along that he currently has a bunch to sell off because he needs the warehouse space. I'm attaching a price list he made up although from my past dealings I can tell you that prices are very much negotiable.
I can put you in touch if you are interested in buying some and can pick up the materials yourself. He prefers to sell in larger quantities of course (ie:15+ sheets at once) since the skids are a pain to move around.
cheers,
Eric
