Earth Hour

Join us in powering down for Earth Hour, which happens every year in March

Get Started

Together, Let's Connect to Earth

*In light of growing concerns over the coronavirus outbreak, we encourage supporters to share their voice for nature online and observe Earth Hour from their own homes to ensure social distancing. Your health and your safety are our top priorities.*

Connect by powering down and experiencing the electrifying energy of Earth Hour as it sweeps across the planet on March 27 at 8:30 p.m., local time. Switch off in solidarity with global efforts to secure nature and our home. It’s time to #Connect2Earth.

About Earth Hour

Starting out as a symbolic lights-out event in Sydney, Australia in 2007, Earth Hour is now the world’s largest grassroots movement for the environment. Last year, millions of people and businesses in 30 participating countries set aside an hour to host events, switch off their lights and make noise for the Earth Hour movement.

As accelerating climate change and staggering biodiversity loss threaten our planet, Earth Hour endeavors are sparking new conversations about habitat loss. Celebrate the diversity of life on Earth. Switch off and be part of the conversation.


Students leading Students

Celebrate Earth Hour in any way you want. Keep it simple with a candle-light dinner, go stargazing, or simply switch off your lights for an hour. Thinking bigger? Organize a campaign calling your fellow students into action to power down where they are, or challenge your faculty or administration to power down. Share your Earth Hour story with WWF-Canada and count your actions towards your Living Planet Leader certification.

Why participate

By disconnecting we’re connecting with the biggest issues confronting the world today. In addition to raising awareness, it gets Canadians talking about the impacts of climate change and inspires action towards building a living planet.

Create impact

Host an Earth Hour campaign and inspire others to take action. Symbolically switching off the lights can create positive ripple effects, inspiring others to consider the role of more sustainability in their lives.

Downtime for the planet...and for you

Relax over candlelight, take a moonlit walk, or take some guilt-free time to reflect and observe the hour.
