McGill sues former head of Canada's spy watchdog

MONTREAL - McGill University is suing the former head of its health centre for more than $300,000.

The Montreal university says the lawsuit demands that Arthur Porter repay the balance of a loan and reimburse an overpayment of his salary.

The cancer specialist resigned from his post as executive director of the McGill University Health Centre last year amid questions about his private business dealings.

Porter's resignation came a few weeks after he had stepped down as chair of Canada's national spy watchdog.

He left the Security Intelligence Review Committee after the National Post newspaper reported that he had forged a business arrangement with a notorious international lobbyist.
