TORONTO - The lights will be switched off at landmarks in more than 250 Canadian cities Saturday to mark Earth Hour.
People the world over are asked to turn off the lights from 8:30 p.m. to 9:30 p.m. local time to show global support for action on climate change.
The World Wildlife Fund says landmarks will be dimmed in more than 115 countries and the 250 Canadian communities signed up is the most of any country.
The environmental group says many corporate leaders have also signed on, including such well-known brands as Coca-Cola and Sears Canada.
Earth Hour is a global WWF initiative that began in Sydney, Australia in 2007, and has since grown into a global movement.
WWF Canada president Gerald Butts says Earth Hour is a "great way to show global support for action on climate change."
