Since Montreal signed up Earth Hour in 2008, a growing number of Montrealers have participated in raising awareness towards the need to take action on climate change.

This year, Montrealers are being invited once again to turn off the lights in their homes and businesses to mark Earth Hour on Saturday night between 8:30 p.m. and 9:30 p.m.

We would love to see your Earth Hour moment. Send us your photos of Earth Hour to mtlcomm@cbc.ca for a chance to win a DVD collection of Nature of Things: Visions of the Future with David Suzuki.

Three winners will be selected and announced on Monday, April 4th.  The enter deadline is Friday, April 1st.
