The nuclear humidity factor: Pickering Nuclear Generating Station sits on Ajax's western border. Its cooling system releases water vapor plumes that increase local humidity. Homes in southwest Ajax near the station experience faster condensation on windows, which mixes with Durham's hard water minerals to create stubborn deposits. If you live near Liverpool Road south of the 401, you may need 3 cleanings per year. Ajax service hub →
