Erich,
Archicad.ca died a death of neglect, mostly because the reseller stopped dealing with Graphisoft. Anyways, I am reposting much of the old ArchiCad East material here on my own site:
www.plusplus.ca under the 'BIM' category or:
http://plusplus.ca/category/bim/
If/when I get time, I will update these items for 13, 14, etc.
