On Saturday, March 26, 2022, The City of Calgary will join other governments, organizations and citizens around the world in shutting off the lights for Earth Hour from 8:30 p.m. to 9:30 p.m.

All non-essential and decorative lighting will be turned off in the following locations:

  • Ad Valorem Place
  • All fire stations
  • Calgary Public Building
  • Dartmouth Place
  • Manchester Centre Building E
  • The Calgary Municipal Building (Historic City Hall, Administration Building, Municipal Building)

In addition, The City of Calgary has partnered with Alberta Council for Environmental Education (ACEE) to deliver the EcoSchools Canada program in Calgary including supporting EcoSchools to complete their action of participating in Earth Hour.

For support, see ACEE's FAQs or contact the EcoSchools in Alberta team. Teachers/Administrators can register their school at any time.
