For this year’s Earth Hour, WWF-Canada is asking people around the world to stand united for a future where climate change is no longer a threat. On Saturday, March 29 from 8:30 to 9:30 p.m., WWF urges Canadians to take part in this global movement and switch off their lights and reflect on the choices all of us can make for a better future. WWF’s Earth Hour is an opportunity for individuals, businesses and communities around the globe to unite in a powerful call to action of hope for a better, healthier planet. As sponsors for WWF’s Earth Hour, Toronto Star and Ontario Power Authority will harness their incredible ability to engage employees and reach customers in spreading our message and encouraging individual action.
