This cold wave also affected Canada. This article needs to be edited to reduce nationalistic POV editing. The cold wave didn't magically appear at the imaginary U.S. border.Ryoung122 19:42, 26 September 2011 (UTC)
Canada is supposed to be cold in January. It may have affected Canada, but very cold temperatures in Canada in the middle of winter are not out of the ordinary. It's not supposed to drop below zero (Fahrenheit, not Celsius) in the southern United States, and therefore this was an incident that was only significant in the United States. 220.127.116.11 (talk) 07:07, 16 April 2012 (UTC)
Any time record-low temperatures are set (Ontario's provincial record low of -73F, for example), it IS an unusual event. Thus, the event was significant to Canada, not just the U.S. Also, what kind of comment is "Canada is supposed to be cold in January"? Ever been to Vancouver?Ryoung122 19:51, 16 April 2012 (UTC)
Just wondering is this is a media story title, that is what it sounds like. in fact it was a Cold wave. Also, the polar vortex does not shift I believe, it fluctuates according to other conditions which may have occurred up to two years prior. So many things need addressing; sorry I do not have time to edit --18.104.22.168 (talk) 15:52, 9 January 2014 (UTC)
