This is a wonderful contrast between everyone in Canada and everyone in the U.S.
There are people here far more knowledgeable about American culture, society,events etc than me but in all honesty I've never met an American who is "smug about their holiday accuracy". I've never even seen it written in print but I could see how such smugness would be resented in Canada, particularly at this time of year while ignoring the 48 hour error.
Some day your great grandchildren may be celebrating that day in early June, 2017 when Ms Freeland announced her own declaration of independence of sorts, declaring the U.S. dead and a new forward looking Canada with its own foreign policy and an increase of 3500 troops to back it up.
So congratulations Canada, the greatest experiment  in government in human history as far as I know.
