Justin Trudeau was sworn in Wednesday as Canada's prime minister, ending 10 years of Conservative rule. Trudeau led his Liberal Party to a commanding victory in parliamentary elections last month, taking 184 seats compared with 99 for Stephen Harper's Conservative Party.
Canadian Prime Minister Stephen Harper has called a parliamentary election for Oct. 19, kicking off a marathon 11-week campaign likely to focus on a stubbornly sluggish economy and his decade in power. Polls indicate Harper's right-of-center Conservative Party, which has been in office since 2006, could well lose its majority in the House of Commons.
