Canadian voters headed to the polls on Tuesday to elect a new Parliament in the third nationwide vote in just four years, dpa reported.
Prime Minister Stephen Harper's Conservative Party was favoured to remain in power with a minority government, with one poll showing them leading with 34 per cent of the vote to 29 per cent for the opposition Liberals.
Harper had called for elections in hopes of securing a stable majority government, but support for the party has slipped in the intervening weeks.
Results were not expected before 0200 GMT Wednesday.
