I always think it's odd how we associate jets with noise,while giving props a reputation for relative silence. If you've ever heard a Piaggo P.180 take off (same props as a Q400, but in pusher format), or for that matter the cottage-bound float planes struggling into the air at full throttle, you'll think that it's not just jets that are noisy.
And forget about the airport. The nosiest thing in the sky over my backyard in Cabbagetown is that damn Ornge helicopter hovering over my house. Air ambulance is an essential service, but other medical services use much quieter aircraft, such as London’s (UK) Air Ambulance.
Here's some interesting info on air complaints from the Island airport from 2009
