I just did a search on canadian specific search term and got the same results on google.com and google.ca. Huh. Anyway, most of the searches would be different on the two Google's.

Wrong test. You need to search for non-specific terms. Sites that also contain Canada-specific terms like, say, for example, "hockey" will rank higher in google.ca than google.com. They don't have to mention Canada by name, though I'm sure it doesn't hurt. (I know this first-hand because one of my directories is loaded down with a Canada-specific term.)
