Head of BPR the 3rd engineering exec to quit in 2 days

Another senior engineering executive has resigned his job in the wake of his testimony before Quebec's corruption inquiry.

Pierre Lavallée gave up his post as president of the Quebec City-based engineering firm BPR today.

Lavallée appeared as a witness before the Charbonneau commission last week, admitting his firm handed over cash to Union Montréal's former fundraiser Bernard Trépanier in order to secure public works contracts.

He said paying a commission to the man known as "Mr. Three Per Cent" was the only way to get a foothold in the Montreal market.

Lavallée called the practice "shameful," but admitted turning over cash to Trépanier in 2007 and 2008.

Trépanier appeared before the commission for a first day of testimony today.

A string of resignations

Lavallée's resignation comes less than a day after Robert Marcil, the one-time director of public works for the City of Montreal resigned from his post as a senior executive with the engineering firm SM International

Earlier yesterday, Rosaire Sauriol quit his job as vice-president of Dessau, the engineering firm founded by his father.
