This post made me shake my head. My dad (and an aunt and uncle) are now Canadian citizens thanks to the same law, and they would have laughed their butts off if any suggested to them that they celebrate Canadian Thanksgiving. I guess DUmmies always need a way to make themselves feel special.
Well, the good thing about it is you can have two Thanksgiving feasts, with a month of recovery between them.
For the four years I was living in Quebec, I switched to the Canadian holiday, since I didn't have any US family within three thousand miles. They did find the idea of marshmallows on yams, and cranberry whip to be very weird.
My mother used to make both, and she was a Jersey girl.
