OTTAWA - A Quebec Liberal MP has announced he's quitting politics for family reasons.

Denis Lemieux, who has represented the riding of Chicoutimi-Le Fjord since 2015, says he made the decision after careful consideration.

He made the announcement in a letter published today on his Facebook page.

The resignation comes a day after Prime Minister Justin Trudeau said four byelections will be held Dec. 11 -- one each in Newfoundland and Labrador, British Columbia, Saskatchewan and Ontario.
