I guess this isn't the typical transition-style re-skilling, but I recently realized I was living near to the George Brown campus that teaches most of the technical/trade skills (near Casa Loma/Dupont subway).
Something to consider if you have continuing education options near you or can't find any other trainer.http://coned.georgebrown.ca/
Just finished the second class of Woodworking and we've started using handsaws and a hand planer. Pretty fun once the curls of wood start flying!
Final Update June 20, 2010
Course completed! Note the fabulous masterpiece sawhorse below, the final project. All-in-all quite a decent woodworking intro, I now have some basic confidence and ability with most of the common hand and power tools. Next, I'll set up a small workshop in the basement and see if I can build on that experience.
Availability of courses like this may be an advantage of Transition in the city; don't despair if you have limited space and no place to garden!
