As a record 441 cities and towns prepared for lights out in Canada, we shared this exclusive image of beautiful wave patterns on the Canadian side of Lake Erie. Lights were dimmed at famous landmarks such as Niagra Falls and the CN Tower, and Toronto hosted a concert where singer/songwriter Andrew Huang performed an Earth Hour anthem, with lyrics written by crowd sourced Facebook submissions. These Earth Hour from Space images were provided by ESA/NASA to celebrated astronaut André Kuipers observing the switch off from the International Space Station.
