MONTREAL—Former McGill University Health Centre board chairman David Angus has been questioned by investigators from the Surete du Quebec’s anti-corruption “Hammer Squad,” according to Montreal’s La Presse.

Citing a number of unnamed sources, the daily reported that Angus, a former federal senator, was questioned about his time heading the MUHC.

On Sept. 18, investigators working for the SQ’s permanent anti-corruption unit raided MUHC offices in downtown Montreal as part of a hunt for information about how contracts were awarded for the construction of the $1.3-billion superhospital at the Glen site.

Angus had chaired the MUHC’s board until January, at which time he was removed as part of a wholesale leadership change at the organization. A month earlier, MUHC director general Arthur Porter stepped down amid a cloud of controversy.

The SQ’s “Hammer Squad” has been operating since 2009, looking for clues of corruption and other economic crimes in the way that the province and municipal governments operate.

Allegations have surfaced that the lead builder at the Glen site, engineering firm SNC-Lavalin, may have paid as much as $22.5 million in bribes secure the contract.

Both the SQ and MUHC have been tight-lipped about the raids and resignations at the organization.
