Groupe Ontario

Au Sierra Club Ontario, notre travail est concentré sur la protection des écosystèmes des Grand Lacs, sur l’expansion et la protection de la « Greenbelt », et de promouvoir l’adoption de l’énergie verte en Ontario. Le groupe travaille aussi sur des projets locaux, en collaboration avec d’autres communautés en Ontario.

The Morvan Road Landfill and its impacts on the African Nova Scotian Community

When speaking of environmental racism, Ingrid Waldon said that "for those who argue that environmental racism is an issue of class and not race, I maintain [...] Race makes class hurt more” (Tillerman, et al., 2003, p.68). In Canada, people of African descent have been disproportionately impacted by environmental hazards, such as toxic air pollution, due to industrialization and colonisation, forcing Black communities into hierarchal systems of abuse and into depreciated environments.

Protecting Mother Earth and Our Future Generations

In Memory of Alicja Rozanska.

As a Mohawk Environmentalist I want to thank CUPE and all of their supporters for protesting Doug Ford's Government and their negative idealism. I attended the protest on Monday November 7th and there were a good ten thousand or more CUPE Union members and citizens present to oppose Ford's Bill.

So you want to learn about plastics?

We all know we have a problem with plastics. But just how deep does the problem go? 

Plastics & waste can be a complicated issue. At every level, across the world, plastics pose a problem to people & the environment. But the good thing is, we are starting to become aware of this and there are a ton of resources to dive deeper into this multifaceted issue.

Canadian Environmental Protection is Getting Stronger, but is it Strong Enough?

The Canadian Environmental Protection Act (CEPA) is a cornerstone of Canada’s environmental legislation. The original CEPA has several shortcomings that fail to meaningfully protect Canada’s environment. A current bill aims to strengthen this legislation -- but does it do enough to protect our environment and our health?

Seaton Trail, The Battle Line

On July 23, Sierra Club Ontario had a walk on the tranquil, beautiful Seaton Trail which forms the battle line between the Rouge National Urban Park and the Pickering Airport Study Area. The walk went from the charming Victorian Gothic village of Whitevale, up to the Oak Ridges Moraine. Here, we turned back after seeing an indicator of good ecosystem health — a Pileated Woodpecker. We were also entertained by a soaring Red Tail Hawk and the sounds of Cardinals, Chickadees, and Wood Frogs. 

Thin Green Wedge Under Attack Again

There is a narrow green wedge of 1.5 kilometers south of the Niagara Escarpment in the City of Niagara Falls. It is a thin refuge for wildlife between a concrete maze of an expressway, quarries, the Welland Canal and a rock dump. It is now under attack. 

North of the green wedge is the Greenbelt, which stretches from Lake Ontario to the Niagara Escarpment. South is the most intact area of Carolinian Canada outside of designated Indian Reservations stretching to Lake Erie. It is dominated by the wetland forests created by the heavy clays of the vanished Lake Tonawanda. 

NPCA Withdraws Notice of Violation for Riverfront

In January 2020, a month after the Local Planning Appeals Tribunal (LPAT) rejected my appeal of the amendment to the City of Niagara Falls Official Plan to facilitate the Riverfront development, extensive mowing took place in a Grey Hawthorn dominated savanna. In addition to Hawthorns being mowed, some small trees were cut down and turned into sawdust — which in some places, buried existing vegetation by mounds three feet deep. 

Plastic Free July 2022 Wrap Up

Our third annual Plastic free July has finished and I want to thank everyone who joined us in the challenge. Whether you had a plastic free picnic, joined us for the Twitterstorm, hosted a clean up in your community or made some changes to plastic use in your household — we appreciate your hard work! 

We ended off the month with a beach clean up at Cherry Beach in Toronto. We had a great turnout and beautiful weather! Thank you to everyone who came out! 

The top items we found during the clean up were cigarette butts and plastic bottle caps. 

Renewing the Ontario Biodiversity Strategy. Working to achieve a nature-positive world.

In its 17th year, the Ontario Biodiversity Council (OBC), came together to achieve the actions set by the Ontario Biodiversity Strategy 2005. In 2011, with support from the Ontario government, Ontario’s Biodiversity Strategy was renewed as a 10-year strategy, aligning with the Convention on Biological Diversity’s global Strategic Plan and its 20 targets, collectively known as Aichi targets. The 10-year strategy is a blueprint, championed by OBC, for an ecologically sustainable future for Ontario, its biodiversity and its people — something well worth pursuing.
