The Québec Auditor General has launched an inquiry into the business practices of the Société des Alcools du Québec (SAQ) alcohol monopoly.

The move is in response to growing public indignation over the resignations of two vice presidents amid a price-fixing scandal.

The investigation will address how the SAQ sets retail prices, the role of agents representing wine and spirit suppliers and how SAQ practices in determining wholesale and retail prices compare with the Liquor Control Board of Ontario, which usually charges lower prices.
