Canadian Liberal Party leader Justin Trudeau arrives at a victory rally in Ottawa on October 20, 2015. Canada is "back" on the world stage, newly-elected prime minister Justin Trudeau said Tuesday after a landslide victory that ended nearly a decade of conservative rule. "I want to say to this country's friends all around the world, many of you have worried that Canada has lost its compassionate and constructive voice in the world over the past 10 years," Trudeau told a rally. "On behalf of 35 million Canadians, we're back" AFP PHOTO/NICHOLAS KAMM        (Photo credit should read NICHOLAS KAMM/AFP/Getty Images)
