Ontario Turns Lights Out For Earth Hour

McGuinty Government Joins Global Event On Climate Change

The Ontario government will join the world in celebrating Earth Hour by turning off its lights.

Earth Hour will occur this year on Saturday, March 27, from 8:30 to 9:30 p.m. This event was launched by the World Wildlife Fund (WWF) in Sydney, Australia, in 2007.  Since then, Earth Hour has grown into an international campaign with millions of people participating.

The lights will be turned off in 63 Ontario government buildings this year.  In addition, the government is taking steps to reduce its energy use in these buildings year round.

Ontario has also been leading the fight against climate change by introducing some of the most aggressive measures in North America.  The Green Energy Act, established last year, has boosted new efforts to increase the province's renewable energy supply.  The government also intends to introduce the Water Opportunities Act. It would lay the foundation for the development and sale of new technologies and services for water conservation and treatment.
