Earth Hour

March 23rd annually

This Earth Hour, March 28  at 8:30 p.m. local time, switch off your lights and #Connect2Earth to draw attention to nature loss in Canada and around the world. 

In Canada, populations of more than one-half of monitored species have already declined by 83 per cent on average since 1970. Globally, we’re on track to lose 67 per cent of wildlife populations by 2020. 

The causes? Habitat loss, pollution, unsustainable harvest, invasive species and climate change, which risks causing one in six species to go extinct. 

“Nature underpins everything around us - from the food we eat, the water we drink, and the air we breathe, to our very livelihoods and quality of life. Nature is vital for all our futures, and is one of our strongest allies against the climate crisis – and yet, the rate of global loss of nature in the last 50 years is unprecedented in human history. We’re the first generation to know we are destroying our planet. And we could be the last that can anything about it.” (

For further information, see Earth Hour and Earth Reminder.

Learn how to participate in Earth Hour  at: Celebrate the Hour.

For resources related to Earth Hour go to: Earth Hour Toolkit.

  • Raise your voice for nature! Visit the following websites: WWF Earth Hour​ or Connect2Earth.
  • Share an action calendar with your students and challenge them with daily actions for a month.
  • Simulate a day in school where energy and resources are scarce, and encourage sustainable consumption habits.
  • Go for a (nature) walk around the neighbourhood! 
  • Switch off all the lights and put up a shadow puppet play with your student. Cut out different shapes of animals, set up a stage using cloth and light and let the shadows come to life!
  • Have a “Bring a stuffed animal and read” day (read about species at risk). Consider animals from Australia.
  • Creative Writing! Have your students write announcements with facts about the top species at risk (tigers, polar bears, narwhal, caribou & reindeer, and Atlantic cod) to share during the week leading up to Earth Hour!
  • Go beyond the Hour – brainstorm small sustainable actions that can continue after Earth Hour.
