Trees are one of our most precious natural resources. They enrich our lives and provide social, ecological and economic benefits.

Forestry Services manages and maintains over 41,500 street trees and 560 ha of woodlot. City owned trees are located on public land areas like boulevards, parks, green spaces and city trails.

Re-greening downtown Oshawa

Discover the City of Oshawa's planting practices to incorporate sustainable tree planting practices into the re-greening and revitalization of the downtown tree canopy.

Sustainable planting practices

To grow a healthy mature tree canopy, the City is implementing several sustainable planting practices downtown aimed at improving growing conditions that include the:

review of tree planting locations to limit conflicts with existing infrastructure, services and pedestrians;
planting of suitable tree species tolerant to urban conditions;
use of soil cell techniques and suspended paving to support the sidewalk above without compacting the soil below;
use of rubberized mulch around the base of the tree to allow water to absorb into the soil; and
installation of watering pipes to be used during times of drought.

How you can help keep our downtown tree canopy healthy

Do not trim or prune the tree. The City's Forestry Services has qualified arborists who will prune and maintain the trees as they mature.
To avoid damaging the bark, which can eventually kill a tree, keep the area around the tree free of debris, do not lean, nail or attach anything to the trunks such as signs or bicycles.
Leave the rubberized mulch at the base of the tree. The mulch is there to protect the tree from damage and reduce water loss.
If you notice that a City boulevard or park trees is damaged or diseased, submit requests to Service Oshawa online.

Tree related By-laws

The City of Oshawa Tree By-law restricts harming of trees located on City owned land.
The Regional Tree By-law applies to Woodlands within the region that are one hectare (2.5 acres) in size and greater. If you are planning to cut down or remove trees within a woodland area, you may need a permit from the Regional Municipality of Durham.
