The July numbers are in:

As mentioned before, sales numbers are indeed higher than the poor showing from last year. (2010 was apparently the worst in a decade, 2011 so far looks to be 2nd worst?)
Year to date, 2011 is about 7% higher than last year.
Still kinda surprised that it's not a lot higher given oil prices, employment rates, and really low interest rates. The recent census results also shows that Calgary has grown about 25% over the last decade as well.
