I thought I’d mention that hacklab.to is awesome. It’s Toronto’s hacker collective!
A wide variety of fields and interests are represented at the lab. There are the things you would expect: software, hardware, math, science, engineering, etc… but also things like linguistics (the creator of Toki Pona is a hacklaber!), lock picking (disturbingly easy: see the MIT Guide), art (Alex recently gave a really neat workshop on block printing), and so on… And of course, there is cross-pollination.
It’s worth mentioning that there’s a CNC laser cutter and 3d-printer.
If you’re a Torontonian and interested, you should definitely come by for the open house on Tuesdays. People are friendly; no one bights!
