No, Calgary simply gets this cold, and has for the entire history of recorded temperatures. https://www.currentresults.com/Yearly-Weather/Canada/AB/Calgary/ext

  That data of coldest days each year is not sufficient to draw any conclusions from. Yes, Calgary gets cold that's clearly not new. What is new, that from some quick google searches, this year they've had both record cold and record warm and record low snowfall and over the summer record fires. Which goes to my previous point that there is something larger going on.
