I'm late to the game, but reading through the comments I'm surprised nobody mentioned the companies that harvest metals from old computer equipment and industrial machines. There is one just outside of Toronto (in Burlington) that takes in large lots of old computers, electronics, wiring, etc. for that purpose alone. Cases get flattened and recycled as scrap metal. When you pass the place on the Go train, you can see mountains of variously processed metals, and what looks like probably crushed/ground up plastics. I imagine they keep the rendered gold elsewhere, though.
