Here's a chart showing the actual average prices: http://www.chpc.biz/uploads/9/7/9/5/9795010/chart-calgary1j_...
The top purple line shows single family homes which peaked at about 500k in 07, about 14 years ago. Now they are supposedly about 550k which is only a few percent rise per year. This is totally consistent with my own house values.
The CBC article says prices are up 9% from last year. It doesnt bother to mention that they aren't much different than 14 years ago.
Edit: I recall about 10 years ago when someone built a house in a nice part of Calgary that was over 3M and people were surprised there was a house that expensive. A quick check shows there are several homes for sale over 10M now and there are over fifty at 3M and up. The high end stuff keeps rising astronomically.
