Calgary Unplugged

Take part in Earth Hour in a COVID safe manner

Usually, as part of our Earth Hour Celebrations, The City of Calgary joins Calgary Unplugged, for a family-friendly Earth Hour event on St Patrick’s Island. This year, we are encouraging citizens to take part in Earth Hour at home or virtually with a community group.

  • Take part in Earth Hour at home
    Join fellow Calgarians in turning off your lights and unplugging electronics, appliances and chargers for one hour, starting at 8:30 p.m. on Saturday, March 27, 2021.
  • Take part in Earth Hour virtually with a community group
    Calgary Unplugged has prepared a Climate Action Toolkit for community groups, including community associations, faith groups, and non-profits, as an alternative to the annual celebration on St, Patrick’s Island.

Go beyond the hour

Join us for the Calgary Climate Symposium March 25-25, 2021 or sign up for one of the many satellite events taking place March 20-27, 2021.

Learn about everyday actions we can all take to manage our energy use and take action on climate change. The more actions we all commit to taking, the greater the impact we can have. Collectively, Calgarians are making a difference. Learn more at
