OTTAWA - Canada's Conservatives stormed to a decisive victory in Monday's federal election, winning 54 percent of the seats in Parliament and securing a stable four-year term in power after vowing to focus on the economy.The Conservatives grabbed 167 seats in Canada's Parliament, well above the 155 they needed to transform their minority government into a majority, according to provisional results. They won about 40 percent of the vote, beating expectations.The victory, a relief for Canadian financial markets, left support for the separatist Bloc Quebecois in tatters and the party's leader without a seat. Bloc Quebecois advocates independence for the province of Quebec.The Liberals, who have ruled Canada for more years than any other party, were reduced to a dismal third place showing with their worst ever seat haul.
