Canada's musical stars have aligned to help Haiti. Avril Lavigne, Drake and Nelly Furtado are among the 57 artists performing together on a remixed version of K'naan's anthem "Wavin' Flag" that will be available for download tonight.

Justin Bieber, Sam Roberts, Kardinal Offishall and Nikki Yanofsky also join the Toronto-raised hip-hop artist in recreating his hit song. Canadian Bob Ezrin produced the track. Proceeds will equally benefit Free the Children, War Child Canada and World Vision Canada and their individual efforts to provide relief to earthquake-ravaged Haiti.
