Trees have played a significant cultural role in the lives of many Canadians; they are engrained in our national identity. Take the Canadian flag, for instance. It features a single, prominent red maple leaf in the centre, which speaks to the abundance of maple trees in Canada and which is Canada’s official arboreal emblem.

Fun fact: There are 10 different species of maple trees native to Canada, including sugar, black, silver, bigleaf, red, mountain, striped, Douglas, vine and Manitoba.

It is hard to consider Canada without trees, especially since forests are at the forefront of iconic landscapes here. Almost 35 per cent of our country is covered with trees. Canada has about 180 different tree species and eight distinct forest regions. Ecologically, trees are important because they provide habitat, food and shelter for many species, they purify our air and water, hold significant amounts of carbon and help control floods.


Today marks National Tree Day, a day to step back, appreciate and be reminded of the numerous benefits that trees provide. Honour trees today by not only helping plant some in your local community, but by learning about some of our country’s great tree species.

Did you know each province and territory in Canada has an official tree? Each represents and reflects the natural and diverse landscapes of the province or territory. Discover your provincial or territorial official tree below.

IUCN (International Union for Conservation of Nature) Conservation status: least concern
Description: Western red cedars are large, tall coniferous trees that can reach heights of up to 60 metres and up to eight metres in circumference. The tree has yellow-green scale-like leaves, with drooping branches and reddish-brown bark. Mature trees have seed cones that ripen in late summer and shed in the winter.
Habitat: A western species, the tree grows best on sites with moist soil that is rich with nutrients. It is found in coastal and interior temperate rainforests of BC.
Interesting fact: Western red cedar is also known as arborvitae, meaning “tree of life,” because it held cultural significance for Indigenous Peoples on Canada’s West Coast. The tree provides shelter, clothing, transportation and medicine.

IUCN conservation status: least concern
Description: A tall, slender conifer growing up to 30 metres in height, lodgepole pine has a straight trunk and dark to yellow-green needles. Needles grow in pairs and in dense clusters toward the end of branches, which curve upward. Lodgepole pine bark is thin, orange-brown to gray in colour and finely scaled.

IUCN conservation status: least concern
Description: A medium-sized tree growing up to 25 metres tall, yellow birch has yellowish-green oval leaves and red-brown bark that is thin and shiny. With age, its bark becomes a dull yellow and darkens to a bronze colour at maturity. Unlike white birch, yellow birch bark does not peel off easily. Instead, it naturally flakes in skinny, horizontal strips.
Habitat: This species grows best in areas with plenty of precipitation and moist, rich soil. It is common in the Great Lakes-St Lawrence and Acadian forest regions of central Canada and the Maritimes.
Interesting fact: When rubbed or scratched, the twigs and leaves of yellow birch release a pleasant minty wintergreen scent.
