National Tree Day is observed in Canada on September 24, as part of National Forest Week, which takes place annually in September. This day was inaugurated by the Parliament of Canada in 2011 to promote the planting of trees and to recognize their value. The event is organized by Tree Canada, a non-profit charitable organization established in 1992, which focuses on various programs aimed at preserving Canada's natural environment. On National Tree Day, Canadians participate in tree-planting activities and educational events that highlight the importance of trees. Additionally, individual provinces celebrate their own Arbor Days; for example, Nova Scotia observes Arbor Day on the Thursday of the first full week in May, while Prince Edward Island celebrates it on the third Friday in May.
