Reinstate the Tree Act (R.S.O. 1990, c. T.20) in Ontario


Reinstate the Tree Act (R.S.O. 1990, c. T.20) in Ontario
The Issue
Ontario, and more specifically Port Colborne, is facing a significant challenge due to the lack of tree shade in our communities. In recent years, policies that require the planting of new trees to replace those that are cut down have been relaxed or removed entirely. This has resulted in a drastic reduction in tree canopy cover, leading to an increase in temperatures, a loss of natural beauty, and adverse effects on the health and well-being of residents.
The Tree Act is a by-law that states that you must plant;
[Dbh stands for: the diameter of the stem of a tree measured at a point that is four and one-half feet above ground.]
(a) 400 trees per acre of any size,
(b) 300 trees per acre measuring more than two inches dbh,
(c) 200 trees per acre measuring more than five inches dbh, or
(d) 100 trees per acre measuring more than eight inches dbh. (“lot boisé”) R.S.O. 1990, c. T.20, s.1
Trees are an essential part of our ecosystem. They provide shade that reduces urban heat, improve air quality by absorbing pollutants, and offer habitats for various wildlife. In urban areas like Port Colborne, where green spaces are already limited, every tree counts. Without the Tree Act, there is no enforced responsibility for maintaining and increasing our urban forests, which are critical in combating climate change and enhancing the livability of our city.
I'm generally focusing on Port Colborne because it has one of the least tree canopies in the region.
In other countries and regions, similar acts have shown significant positive impacts. For example, in cities like Melbourne, Australia, the implementation of urban tree strategies has resulted in increased shade, cooler street temperatures, and improved community well-being. These are outcomes that are invaluable to urban centres.
Trees are also important in an environmental level, giving houses to animals (a part of the Tree Act) and to help remove the pollution from the air.
We urge the Ontario government to reinstate the Tree Act, mandating that for every tree removed, a new one must be planted. This will ensure a sustainable approach to urban development and maintain the vital balance between nature and urbanization. By doing so, we not only preserve the beauty and environmental health of Port Colborne and other Ontario towns but also set a positive example for future generations.
We need your support to make this a reality. Sign this petition to urge the Ontario government to bring back the Tree Act and protect our urban tree cover for current and future generations. Together, we can ensure a greener and healthier Ontario.
Hopefully, with all of your support, I can send this to my MPP of my region and I can actually get it reinstated.
