Quebec's corruption inquiry is set to resume Tuesday, Sept. 3, after a two-month summer break.
This time the province's unions will be put under the microscope.
Six members of the powerful FTQ construction union are expected to testify at the inquiry this fall, including top boss Yves Ouellet.
The commission is also expected to delve into construction contracts involving Quebec's transportation ministry as well as cities around the province.
The inquiry has heard from 80 witnesses so far, including mayors, city officials and engineering executives.
It was granted an 18-month extension from the provincial government and Chair France Charbonneau must now deliver her report by April, 2015.
