What evidence is there that Calgary is getting colder? I would believe we are getting more snow, but that is something that is predicted in global warming models (warmer air holds more moisture?).
This link talks about average weather conditions in Calgary from 1999 to 2012:

It turns out -- and any Calgarian can attest to this -- winter is by far the most varying season, year-to-year. In the past, two consecutive winters can be as much as 10°C different in overall temperature.
However, within the highly-varying temperatures of a Calgarian winter, there does appear to be a warming pattern. Winters just aren’t as cold as they used to be. Before 1980, Calgary used to have three winters per decade of -10°C on average or lower. Since 1980, the average is less than 1 per decade.
