After several months of bombshell testimony that focused mainly on municipal contracts, the Quebec corruption inquiry has taken time off from its busy schedule to regroup.

When the Charbonneau Commission resumes in mid-January, the fight against corruption will turn to the provincial arena.

During its fall sitting, testimony led to the departure of two of Quebec's longest serving mayors in Montreal and Laval.

The corruption inquiry has a lot of ground to cover next year and is supposed to report back in October.

But Charles-Maxime Panaccio , a University of Ottawa law professor, says its mandate should be extended well beyond the current Fall deadline.

He says the inquiry should get as much time as it needs to get to the bottom of the issues.

It has also come under criticism for naming plenty of names without giving those people a chance to defend themselves.

Commission chair France Charbonneau has said that everyone who wants to be heard will be and those with relevant information will testify publicly.

There are more than 20 ongoing investigations -- not only into the construction industry -- but also into hospitals and computer-service contracts.

Quebec's highly-touted northern development plan is also being investigated.

The next wave of testimony could also potentially include longtime Mafia boss Vito Rizzuto.
