Martial Fillion, a man co-accused in the Faubourg Contrecoeur scandal, has died.

 Fillion died Tuesday -- reportedly of a heart attack -- at age 59.
He was the former director of the Montreal housing and development agency SHDM, and also served as chief-of-staff of former mayor Gerald Tremblay.

Fillion was arrested last May, along with the former president of Montreal’s executive committee Frank Zampino, and businessman Paolo Catania.

Police said the arrests and subsequent charges were related to a property deal in 2008 when the City of Montreal sold a piece of land in the East End for a massive condo project, the Faubourg Contrecoeur, at far below market value.

A La Presse investigation revealed that the land was valued at $31 million by the city, but was sold to Catania Construction for just $4.4 million.

Fillion's name has come up often during the Charbonneau Commission, the public inquiry into fraud in Quebec's construction industry.

Fillion was expected to appear in court next month in connection with the Faubourg Contrecoeur scandal.
