As a group, pines are still the most common Canadian conifers and yield lumber, pulp and paper.
Early French settlers were exporting pine from as early as 1700 (Canada became a country in 1867) as well as using it for construction and shipbuilding. In the province of Ontario, the tallest pine is 47 metres (154 feet) high or roughly the same height as a 13 storey building.
They are photogenic trees and often served as subjects in paintings by The Group of Seven, a group of Canadian landscape painters from 1920 to 1933 who pioneered a distinct nature focused art style.
