This document summarizes corruption in Quebec's construction industry as uncovered by the Charbonneau Commission. Public officials accepted bribes like money, donations, wine and prostitutes from construction firms. This allowed cartels to unfairly win contracts through bid-rigging, bribery and collusion. Over $36 million was spent on the commission with effects including higher prices, less innovation, and damaged public trust. Consequences included resignations of mayors and executives facing charges. Reforms have been implemented but more is needed like stiffer fines, banning corrupt companies, and increased transparency.
