Ontario’s Plant a Tree Challenge


















Use the Tree Atlas to learn more about Ontario’s trees, and to find out what trees grow best where you live.

Trees are part of what make Ontario beautiful. There are dozens of species of trees found in our province, from the tall and mighty eastern white pine to the blossom-covered pin cherry.

But trees do more than just look beautiful. They shade our homes, provide food and habitat for birds and animals, and help to fight climate change. When we plant trees, we’re helping to build a greener and cleaner Ontario. Trees prevent soil erosion, which can also help protect the quality of our water.

Trees are an important part of our biodiversity. A healthy natural environment supports many different kinds of plants and animals. Trees provide shelter, food and habitat for a huge variety of mammals, birds, insects, plants and even helpful bacteria.

The best kinds of trees to plant are native species. These are trees that have been growing in Ontario for centuries – they’re part of the history of our province. Native tree species are adapted to our environment. They belong here and they contribute to the interconnected web of life that sustains us. Introduced species (that have not been in Ontario for a long time) do not support local ecology and can harm other trees, plants or animals.

Different trees need different conditions. Some grow best in wet soil, and others prefer sandy and dry soil. Many trees need full sun; others can survive in shady spots. Tree roots can be shallow and widespread, or they can grow deeply into the earth. It’s important to research different types of trees and talk to an expert before deciding to plant your own tree.

Consider your own needs: Do you want to a tree that will shade your house to keep it cool in the summer? Do you want to attract wildlife and birds? Or do you want a fast-growing bushy tree to hide an unsightly view?

Recognizing different tree species will help not only with choosing a tree to plant on your property, but will help you identify different trees in your neighbourhood or when you go for a walk in the woods.

The trees listed here are the most common trees likely to be found in south and central Ontario.
