THIS MUSEUM, housed in an old stone warehouse belonging to an ancient order of nuns, has an extensive collection of Fortin’s work, and it also mounts exhibitions of new painting by local artists.

Marc-Aurèle Fortin transformed landscape painting in Canada. He was born in 1888, when European styles dominated North American art. Fortin loved the light of his native province, and used many unusual techniques.

To capture the ‘‘warm light of Quebec,’’ for example, he painted some of his pictures over gray backgrounds. By the time he died in 1970, he left behind not only a staggering amount of work but a whole new way of looking at nature, especially the various rural areas of his native Quebec.
