If you don't mind going to a dealer, go to Mississauga Toyota 427 & Dundas, across from the Muddy Duck. The service manager Dave, and his brother John, and also Shelly will treat you well. My wife and I have gone there for years with a variety of Toyota models and we've never had a problem. Always treated well, service is done right, and most times they don't even charge for the little things. We've never purchased a car there, but we always take them there for service - we have many people to them and they have all been happy.
You might want to go to
www.matrixowners.com because I know that there was a topic about good and bad dealers (for service) in the GTA - there were olts of good ones, and definitely one or two to stay away from.
