MONTREAL — New York Mob infiltrator Joe Pistone, a.k.a. Donnie Brasco, will be the next star witness at Quebec's corruption inquiry, QMI Agency has learned.

The man who helped bring down the Bonanno crime syndicate and lived to tell about it will testify, face uncovered, about the Mafia's role in public contracting.

He is scheduled to take the stand Monday at commission headquarters in downtown Montreal, sources tell QMI Agency.

The event will be televised live and the 72-year-old is expected to answer questions for at least a half day.

Judge France Charbonneau is examining the role organized crime plays in public infrastructure projects and political party financing.

Quebec's former anti-corruption czar, Jacques Duchesneau, told the legislature last year that the Mafia launders cash at construction sites across Quebec.

He later told the inquiry about firms that conspire to inflate the value of public contracts before funnelling cash to political parties.

The former Montreal police chief also testified that dirty money accounted for a whopping 70% of political donations in the province.

The scandals were a factor in Quebecers' decision to kick Jean Charest out of office last week.

Joe Pistone gained firsthand knowledge of Mob activities from 1976 to 1981 when he penetrated deeper into organized crime than any FBI agent in history.

Using the alias Donnie Brasco, Pistone posed as a mid-level foot soldier in the Bonanno crime family.

He gained the confidence of top mob leaders before turning his information over to his FBI bosses.

Prosecutors built an iron-clad case that resulted in stiff jail sentences for top Mob leaders in the 1980s.

New York subsequently formed a permanent anti-corruption unit that premier Charest duplicated in Quebec as he tried to dodge allegations that dirty money made its way into his Liberal party.

Pistone's story was adapted for the big screen in the film Donnie Brasco, starring Johnny Depp and Al Pacino.
