I live a good distance from YYZ but am on the approach route used on most days (when there is a west wind). The earlier start means that those arrivals are flying over my house well before those gate arrival times. Thanks for the bad news.
Did you build or purchase your house prior to 1939? If not than you really don't have anything to complain about since the airport would have been there when you built/bought.
If you did buy before 1939, then B!tch away!
