The Laurentian Mountains, also known as the Laurentians or Laurentides, are a mountain range in Canada. The range is 1,448 km (900 mi) long and ranges in height from 500 m (1,640 ft) with peaks over 1,000 m (3,280 ft). The Laurentian Mountains extend across Labrador and Quebec within the Laurentian Upland, which contains foothills in northeastern Ontario. The range is located near the rivers of Ottawa, St. Lawrence, and Saguenay. The Laurentian Mountains primarily stretch across multiple regions in Quebec, with geologic formations such as the Jacques-Cartier Massif located within the range.
The Laurentians Mountains are one of the oldest mountain ranges on earth. The range formed around one billion years ago during the Grenville orogeny, in which the Grenville Province formed, a subdivision of the Canadian Shield. During that time, Laurentia, the geologic core of the Canadian Shield, collided with other continents and formed Precambrian rocks which extend across the range. The mountain range is located around other related geographic features, such as the Monteregian Hills and the Adirondack Mountains.

Forestry
The Laurentian Mountains have been historically used for logging. During the European colonization of North America, colonists were met with a woodland that stretched from the East Coast to the Great Lakes. The forests reached heights of 30 to 85 meters high. While the exports of logging grew, it eventually became a wasteful practice, with the felling of trees leaving huge portions of land vulnerable to erosion.[17] Intensive forestry has not entirely ceased in the region. Public and private forests in Quebec have now been entirely mapped, with information such as the soil, terrain, and waterways, and the species and the age of the trees available. With this data, the chief forester calculates the amount of wood that can be harvested, ensuring the forest is not cut down faster than it can grow back.[13]
