OTTAWA (Reuters) - Canada's ruling Conservatives have a huge lead over the opposition Liberals and are well on their way to winning a majority government in the Oct 14 election, according to a poll released on Wednesday.

The Segma survey for La Presse put the Conservatives on 42 percent support compared to just 23 percent for the Liberals. A poll by the same firm released on Sept 8 put the Conservatives ahead by 43 points to 25.
