The Competition Bureau lays charges against two executives in a bid-rigging case in Montérégie

News release

September 19, 2023, GATINEAU (Quebec), Competition Bureau

Criminal charges were laid before the Court of Quebec against two individuals in connection with alleged bid-rigging for paving contracts awarded by the ministère des Transports du Québec (MTQ) for the Montérégie region.

Marcel Roireau and Serge Daunais are charged under the bid-rigging provisions of the Competition Act. The evidence gathered by the Competition Bureau suggests that the accused individuals allegedly participated in an illegal agreement with their competitors to submit cover bids in response to the calls for tenders launched by the MTQ in 2008.

At the time of the alleged offence, Marcel Roireau was Vice President of Operations for Construction DJL Inc. and Serge Daunais was Vice President, Secretary and General Manager for Pavages Maska Inc.


“The charges laid in connection with bid-rigging reflect our commitment to protect and promote fair and healthy competition in our economy. We will continue to pursue colluding bidders who divert public funds.”

Matthew Boswell
Commissioner of Competition
