The Observatoire du Mont Mégantic (Mont Mégantic Observatory in English) is an astronomical observatory owned and operated jointly by the Université de Montréal, the Université Laval and the McGill University. Founded in 1978, it is the largest observatory of eastern Canada, and is situated at the summit of Mont Mégantic, the highest point of the province of Québec to be accessible by car.
The observatory (IAU code 301) is about 250 km east of Montréal and about the same distance south of Quebec City.
The telescope is equipped with a complement of modern instruments: visible imagery, spectroscopy and polarimetry are routinely conducted. There is also an infrared imager, but it is often "borrowed" by astronomers observing at the Canada-France-Hawaii Telescope (CFHT).
The current director is René Doyon.
Efforts to control local light pollution (about one-quarter of which is due to the nearby city of Sherbrooke) have led to the establishment of the world's first International (from [www.wikipedia.org](http://www.wikipedia.org/wiki/Mont_Mégantic_Observatory).
