Multi-platinum Juno and Grammy Award-winner Nelly Furtado will be gracing Toronto's Earth Hour event this year with a free concert.

Multi-platinum Juno and Grammy Award-winner Nelly Furtado will be gracing Toronto's Earth Hour event this year with a free concert.

The Victoria native, known for hit singles such as Promiscuous, Maneater and Say It Right, has been named Canada's first Earth Hour ambassador.

From 8 to 9 p.m. on March 29th, cities around the world will be turning off their lights to raise awareness about climate change.

Canada is leading the way with 50 cities and 1,000 businesses signed up so far.

The World Wildlife Fund of Canada (WWF-Canada), organizers of the event, says it will be as carbon-neutral as possible and will be powered with green, renewable energy.

Last year's inaugural Earth Hour was held in Australia. An estimated 2.2 million Australians participated, reducing demand on the power grid by 10 per cent.

The event has since caught on around the world.

"It's a step and it lets people see how individual actions add up," Tara Wood, spokesperson for WWF-Canada, told The Toronto Star.

"Earth Hour is a great celebration of what we can accomplish together and it gets us thinking about simple steps we can take to make every hour Earth Hour."

Furtado won Junos in 2007 for her single Promiscuous, Album of the Year and Pop Album of the Year for Loose,as well as Artist of the Year.
