Hi Costad,
As FALLSDUDE said Canadian Thanksgiving is long gone (2nd Monday in October). Here though are a couple of ideas:
(1) Check out Swiss Chalet, it is a Canadian Rotisserie Chicken restaurant chain... a family restaurant. They run a "festive special" up until Christmas that includes Chicken (Breast or Leg Quarters), your choice of potatoes (fries, mashed, etc) stuffing, cranberries, and dipping sauce, as well as Lindt Chocolates when you leave.
It isn't homemade Turkey, but it can fill-in in a pinch.
(2) You can always slip back across the border to Niagara Falls NY for your Thanksgiving Meal. The part you have to be aware of though is that by breaking up your visit out of the country, you could effect your customs exemption on your return to the USA (that is if you are planning to do any shopping and bring anything back into the US from your visit... there are exemption amounts tied to the length of continuous time you are out of the country).
Hope this is helpful,
Cheers!
