Many Canadians will be spending an hour with the lights out tonight as they join people around the world in marking the tenth annual Earth Hour.

The event is aimed at drawing attention to climate change and for people to show they support efforts to reduce greenhouse gas emissions.

The World Wildlife Fund has championed Earth Hour since 2007 when it started in Australia.
