Calgary's commitment to Earth Hour

On Saturday, March 25, 2017, The City of Calgary joined other governments, organizations and citizens around the world in shutting off its lights for Earth Hour from 8:30 p.m. to 9:30 p.m. All non-essential lighting was turned off in the following locations:

  • The Calgary Municipal Building
  • Calgary Public Building
  • Manchester Centre Building E
  • Water Centre
  • all fire stations
  • Centre Street Bridge
  • the 4th Street S.E. underpass
  • Reconciliation Bridge

Go beyond the hour

Beyond participating in Earth Hour each year, The City will work to continue to find new opportunities to reduce energy use every day. You can also do your part to reduce your impact by taking simple steps to save energy.
