Founded in 1980, this outstanding opera company (it's one of the 15 largest in North America) mounts six productions per year in Montréal, with artists from Québec and abroad participating in such shows as Mozart's The Magic Flute and Puccini's La Bohème. Video translations are provided from the original languages into French and English. Performances are held from September to June at Place des Arts. Just next door, a new concert hall, L'Adresse Symphonique, was scheduled to open in September 2011.
