Earth Hour

On March 28, 2026, we’ll be celebrating Earth Hour’s 20th anniversary — and you can be part of it!

Earth Hour has come a long way since it first started in Sydney, Australia, in 2007, growing to unite millions of people around the world. Every year at 8:30 p.m. local time on a Saturday in late March, a global community comes together to raise awareness of the nature crises facing our planet — and inspire action.

Here in Canada, nature needs our support more than ever. Our latest Living Planet Report Canada revealed the starkest picture of wildlife loss to date, and climate change impacts are intensifying, with communities across the country facing more devastating wildfires, droughts and floods.

Nature provides the clean water, air and food we rely on, helps to protect our communities from climate impacts, and is central to our cultures and national identity. It’s the foundation of healthy ecosystems that sustain wildlife and our economy.

Earth Hour is an opportunity to show just how much we care, and that protecting and restoring nature is a top priority for Canadians. 

On Saturday, March 28, join millions of people around the world in making a difference. Let’s make the 20th Earth Hour one to remember!
