Arthur Porter's wife to remain detained after turning herself in to police

MONTREAL - The wife of alleged fraudster Arthur Porter will remain behind bars until at least the end of her trial.

Pamela Porter turned herself into Quebec provincial police on Wednesday and was arraigned several hours later.

The 54-year-old faces a new charge of money laundering as Quebec's anti-corruption unit alleges some of the money used to secure her bail in 2013 came from proceeds linked to alleged fraud of $22.5 million.

Porter is among several people who are charged in the awarding of a $1.3-billion contract for the McGill Superhospital in 2010, a group that includes her husband.

Pamela Porter already faces one charge of conspiracy and another related to the alleged money laundering.

She will next appear in court on Sept. 15.

"We have asked that she remain incarcerated," Crown prosecutor Marie-Helene Giroux said Wednesday. "She had the right to request bail on the new charge but her lawyer waived it."

Currently, a preliminary hearing in her case is only expected in March 2015. Porter is seeking to speed up court proceedings.

Arthur Porter is the former head the McGill University Health Centre and was once appointed by Prime Minister Stephen Harper to head the Security Intelligence Review Committee, a CSIS watchdog group.

He is still in a jail in Panama where he is fighting his extradition to Canada.
