Quebec’s anti-corruption squad is searching the offices of the McGill University Health Centre in downtown Montreal this morning.
A spokesman for the unit says around 10 investigators from the department’s Hammer Squad are looking for signs of illegal activity.
Squad members are interviewing witnesses during the operation.
There are no immediate reports of arrests.
Quebec introduced Operation Hammer in late 2009 amid a flurry of corruption allegations that shocked the province.
The squad has been involved in a number of arrests since its inception.
