Earth Hour takes place from 8:30 p.m. to 9:30 p.m. local time on Saturday (March 29).
The occasion sees people all over the world dim the lights for a single hour to raise awareness of environmental issues.
Previous years have seen world landmarks such as the Sydney Opera House, the Burj Khalifa and London's Big Ben go dark.
We compiled a list of major landmarks throughout North America that will turn down their lights for 60 minutes.
And tell us: how do you plan to celebrate Earth Hour?
