I was in Calgary on Sept 20th or so and it was 34 degrees.
calgary is not infested like the Lower Mainland, or Toronto, or Montreal, or even Halifax for that matter, with all sorts of low life...
If you want a good, clean city to study in and advance your career, Calgary is a fine option.
The favourite saying I have heard in Calgary is "Calgary has done right by me". Thats a pretty good thing these days.
