Ontario Joins The World To Mark Earth Hour

McGuinty Government Reduces Energy Use

Ontario is joining the world in marking Earth Hour by turning off the lights in government buildings between 8:30 and 9:30 p.m. tomorrow evening.

Earth Hour is a global event highlighting the importance of conserving energy and working together to reduce energy use and tackle climate change. Everyone can make a difference by taking steps to cut our energy use at work, at school and at home.

Ontario has also been working to reduce greenhouse gases by phasing out coal, promoting conservation and building a clean, reliable energy system, helping to:

  • Conserve energy and generate peak demand savings of more than 1,700 MW of electricity since 2005, which is the equivalent to taking more than half a million homes off the grid.
  • Create thousands of new, good jobs in the province.
  • Clean up the air we breathe - last year, four coal units were closed, the equivalent of taking two million cars off Ontario's roads.
These actions are an important part of the government's Open Ontario Plan to build a stronger economy and create jobs, while protecting our environment.

Quick Facts

  • The World Wildlife Fund launched the first Earth Hour event in 2007 in Sydney, Australia. Since then it has grown into an international campaign with millions of people participating.
  • Over 70 buildings owned by the Ontario government will participate in Earth Hour.
  • In 2003, Ontario had 19 dirty coal units and just 10 wind turbines. Today, the province has more than 800 wind turbines and by the end of 2014 all coal units will be closed.

“I encourage all Ontarians to participate in Earth Hour. There are so many simple things, like turning off the lights, we can all do together. Small steps by a lot of people can make a big difference in conserving energy, saving money and protecting our environment. Working together let's leave a healthier, cleaner environment for future generations.”

John Wilkinson

Minister of the Environment

“The McGuinty Government is proud to support Earth Hour as a symbol of what we can accomplish when we work together.”

Harinder Takhar

Minister of Government Services

“Conservation is the easiest way for Ontarians to manage their electricity use, and a key part of the province's plan to get off dirty, smog-producing coal plants and clean up the air we breathe. Earth Hour shows how small steps can lead to big energy savings when we all do our part.”
