After the update of Toronto Multiple listing service (MLS) on July 5, 2011, the Toronto Real Estate Board (TREB) introduced a new search feature for the Toronto MLS, used by real estate agents operating in the region. MLS searches can be refined at three levels and MLS users can search houses by area, then by municipality, and then by neighbourhood or community. As with the other MLS services for other jurisdictions, it used Microsoft's Bing Maps for its web mapping features until 2018, when it switched to Google Maps. These feature changes were the first change of this magnitude in about 50 years of Toronto MLS history.
