Unusual Canadian Cold?

I usually do not check the maps during the summer, but I don't remember it being so cold in northern Canada during the dog days of summer. It may be totally normal, but that cold seems to stay there throughout the 15 day period, and infact seems to get stronger and more expansive by the end of the forecast period, mid August. Anyone have any knowledge of this...I'm sure it is totally normal, but cool to see the first signs of fall perhaps.
