Earth Hour is an event designed to raise awareness -- and lower energy use! On Saturday, March 27 from 8:30-9:30 PM the city of Toronto will be turning off its lights. To mark the occasion, they're offering a free concert in Yonge-Dundas Square with Chantal Kreviazuk along with Jarvis Church and Justin Nozuka.

The concert will be powered with Green Electricity from Bullfrog Power. Opening remarks start at 7 PM, followed by performances by Justin Nozuka and Jarvis Church. Chantal Kreviazuk takes the stage at 8:30 PM.
