Below is a map that shows the percent changes in Home Price Index (HPI) of condo apartments for Toronto's districts with at least 30 sales. While condos in the northeastern part of the city were appreciating, condos in the southwestern part were losing value.

The reason that I chose to look at HPI is because it accounts for the expensive properties that can skew the statistics (especially when looking at small samples). Just take a look at Yorkville and Vaughan stats below.
Condo Apartment Stats for Various Areas:
Eastern Downtown - average price down 2%, median price down by 6.5%, HPI down by 2%
Western Downtown - average price UP by 1.5%, median price down by 1%, HPI down by 1.7%
Yorkville - average price UP by 29%, median price down by 23.3%, HPI down by 3.2%
Vaughan - average price down by 11%, median price down by 5%, HPI UP by 5.6%
Overall the average condo price in the City of Toronto went up by 0.5% in June 2013. The median price decreased by 1.4% and the HPI went up by 0.5%. Sales fell by 6.1% compared to a year ago! Compared to 2011 condo sales fell by 24%.
