New Website Coming Soon!
We are busily working on a new website to replace this old one that has served us for many years.

Over time the code behind web content management tools becomes outdated, and eventually it's better to completely redesign a new site rather than simply updating old code. This site has reached the point where entering updates is truly painful and very time consuming.

If you are interested in courses, please call the office at 647-466-2436, or email us at the address provided in the "More Information" section above (replace the bracketed information with the conventional @ sign for emails). We have a full slate of classes starting in the Fall term.

We promise the new site will be much prettier, provide much more information, and will be updated and enhanced on an ongoing basis, so check back around mid-November 2014 for the opportunity to sign up for updates on classes, meetings and shows.
