PETERBOROUGH, Ont. - Prime Minister Stephen Harper says he plans to make good on an election promise to improve representation for three provinces in the House of Commons.

He says his government is committed to increasing representation for British Columbia, Ontario and Alberta to better reflect increases in population.

The proposal to add seats came during this spring's federal election campaign, which gave Harper's Conservatives a majority government.

And on Friday, Harper even cited the page number in his election platform that makes the promise.

The plan is not popular in Quebec, where it's feared the number of seats would not increase.

Harper made the comments in Peterborough, Ont., where he was attending a ceremony marking the expansion of the Peterborough Municipal Airport.
