Great Lakes Section


The Great Lakes Section of SCO started in 2010. It is led by veteran Great Lakes advocate Mary Muter and comprised of Sierra Club members with specific experience and focus on Great Lakes issues. They are addressing the multiple components of the Great Lakes ecosystem using bi-national coordination of activities with the Sierra Club in the States.

Challenge To Urban Sprawl: Grow The Greenbelt

Sierra Club  Ontario 's Challenge to Sprawl campaign is currently focused on Growing The Greenbelt. Building on support from the Friends of the Greenbelt Foundation, Sierra Club Ontario has been making advances in protecting threatened ecosystems in Peel and Durham Region.

Under the leadership of Sierra Club Peel volunteers public and political support for protecting the Credit River Watershed is expanding daily. Sierra is working with City of Mississauga staff and elected officials to fulfil their City Council resolution of 2010 to protect the Credit River as a Greenbelt Urban River Valley. 

Car Free Day

Car Free Days aim to be fun, free events encouraging people to get out of their cars and run, walk, cycle or take public transit. The central vision of Car Free Day is urban mobility that is not dependent on the private automobile. 

International Car Free Day (CFD), celebrated every Sept. 22, first started in Europe in the 1990s and is a growing global movement celebrated in over two thousand towns and cities in over thirty countries. CFD is not anti-car, but promotes awareness of alternative forms of transportation and the public health benefits of more active lifestyles within reach to us all.

Coal Fire Plant Phase Out

In Ontario, coal power plants supply approximately 10% of the energy used to power factories, homes and businesses. However, the negative environmental effects of burning coal are well known: increasing CO2 and methane concentrations in the atmosphere and release of toxic heavy metals.

Great Lakes Symposium - Schiefer presentation

Publication Date: 
April 8, 2011

Karl Schiefer, a consulting Aquatic Biologist, gave this presentation "Great Lakes Ecosystems: Do We Value Them?" at our Port Huron event. Schiefer gives a brief history of human uses and impacts on the Great Lakes with a focus on Huron/Georgian Bay. Schiefer says our European value system (an anthorpocentric world-view with an emphasis on advanced technology) dominates our management of the Great Lakes. This has a huge impact on the environment as compared to the First Nations that coexisted with the resource for millenium without depleting it.

Submission to the Darlington New Nuclear Power Plant Project Joint Review Panel

Publication Date: 
February 22, 2011

There is no justification to accept either the expense or the risks of nuclear technology. All it takes is the courage to stand up to the nuclear lobby. Sierra Club Canada along with thousands of Ontarians is not convinced there is any justification for accepting the risks to health, the environment or the economy presented by the proposal to build additional nuclear reactors.

Pickering Airport/ Duffins Creek

Land in North Pickering was expropriated during the 1970's to be used as an airport. The plans were contested from the start and citizens stopped the original proposal. Now, thirty years later the issue has resurfaced. This time it is not only the lands at risk, but also the last remaining undeveloped habitat to many species.

Lake Simcoe sprawl plan a.k.a Proposed Amd. 1 for Greater Golden Horseshoe

Publication Date: 
January 31, 2011

The “Proposed Amendment 1 to the Growth Plan for the Greater Golden Horseshoe” is a plan for more sprawl development in the Lake Simcoe watershed.  See SCO's letter submitted against the approval to the Ontario Gorwth Secretariat, Jan 31st.

Citizens simply will not buy the province’s line that this plan represents responsible growth.  We know sprawl when we see it.  We know this proposal will exacerbate highway congestion, strain water supplies, pollute surface and ground water, and encourage leapfrog development.
