When is Thanksgiving in Canada?

I didn't actually ever really think of Canada as having a Thanksgiving until I had a Canadian friend in college. Yes, when other people were partying and finally getting much needed help in drug rehab treatment centers I was like "Ohh they have Thanksgiving in Canada too?" Then, I remembered this again on "How I Met Your Mother" when they were accusing Robin's Thanksgiving of not being a real Thanksgiving. This apparently occurs on the second Monday in October. I think Monday is a much more practical time as far as the work week goes to have Thanksgiving. Then I read this Thanksgiving Canadian menu to see if the food was different. There seems to be slightly more vegetables, as well as beet soup.
