PaperTiger,
Check out the TC site and take a look at the Do-328 Canadian type certificate.
Its relatively new and contains a great deal of Canadian standards and requirements. I can assure you that the standards listed are not just lip service. A great deal of substantiating data needed to be prepared to support compliance. Notice the "Canadian Configuration" section that piles on a service bulletin that must be embodied. As I mentioned, the hurdle is not insurmountable (usually) be it is a hurdle all the same.
Cheers.
