MONTREAL - Anti-corruption officials in Quebec say a ninth person is facing charges in the alleged fraud of $22.5 million related to the awarding of the McGill University superhospital project.

Authorities say former SNC-Lavalin vice-president Stephane Roy held a senior position overseeing construction finances at the engineering giant.

Quebec's anti-corruption unit says Roy was arrested today and faces 11 charges.

Authorities allege that ex-SNC-Lavalin executives funnelled money to former McGill hospital officials in exchange for the $1.3-billion contract.

A preliminary hearing in the case is expected in 2015.

Those facing charges include former McGill hospital executive Arthur Porter and his wife Pamela; ex-McGill executive Yanai Elbaz and his brother Yohann; ex-SNC Lavalin head Pierre Duhaime; and another former vice-president, Riadh Ben Aissa.
