Pontiac is a municipality in western Quebec, Canada, in Les Collines-de-l'Outaouais Regional County Municipality on the Ottawa River. It should not be confused with Pontiac Regional County Municipality, which borders Pontiac (but does not include it). Pontiac was created by the 1975 amalgamation of Onslow, Eardley, Quyon and Onslow-Partie-Sud. Pontiac has a low cost of living and is trying to attract new immigrants coming to Canada to improve the local economy.
