Earth Hour

Saturday, March 27 at 8:30 p.m. local time

Every year and everywhere, at 8:30 pm on the last Saturday of March, millions of people across the world join in raising awareness of the nature crises facing our planet.

It’s not just a symbol of support — it’s a catalyst for urgent change because Earth Hour is about more than sixty minutes. It’s a movement for our future.

Join us on Saturday, March 27 at 8:30 pm local time to let our leaders know we want action on climate change, biodiversity loss, and wildlife conservation.

It’s time to make nature matter.

A message of hope this Earth Hour

This Earth Hour, WWF-Canada is also inviting supporters to reflect on the wins for wildlife and nature that have been earned by tireless conservation efforts by individuals, Indigenous communities, businesses and governments.

While we might feel numbed by the seemingly endless cycle of bad news about biodiversity loss and the climate crisis, there are also countless stories of recovery that provide inspiration and hope.

Consider the whooping crane, a species that declined to only 14 individuals due to pressures like habitat loss and hunting. Today the species is recovering, thanks to conservation efforts including protected areas, especially in Wood Buffalo National Park, their exclusive wild breeding grounds in Canada.

Recovering wildlife and reversing climate change is possible. Join us this Earth Hour and be inspired to fight for the planet, people and future.
