Saint-Michel Environmental Complex

The Saint-Michel Environmental Complex (CESM) is an immense 192-hectare site in the heart of the Villeray-Saint-Michel-Parc-Extension borough. This site, once home to the Miron limestone quarry, was converted in 1968 into a giant landfill of 75 hectares. Eventually acquired in 1984 by the City of Montreal, their goal was to turn it into a vast environmental technology and education complex surrounded by green space, helping to improve the cultural and recreational life of the area.

Today it has become the second largest green space in Montreal, after Mount Royal Park. This is one of the most ambitious environmental restoration projects ever undertaken in a North American urban area.
