Professional: As a cancer specialist he worked in Edmonton and London, Ont. as well as Detroit. He founded a cancer clinic is Nassau, the Bahamas.

He ran the Detroit Medical Centre in Michigan, then the McGill University Health Centre.

He taught at McGill, the University of Tennessee and the University of the West Indies.

In 2008 he was appointed to the Security Intelligence Review Committee by Prime Minister Stephen Harper and sworn to the Privy Council. In 2010 he was made chairman of the committee.

The controversies: When he resigned from the Detroit Medical Center in 2003, it was mired in debt. In 2011, he resigned from SIRC after he admitted he had wired money to an international lobbyist related to an infrastructure project in Sierra Leone. A few weeks later, he left McGill University Hospital under a cloud because of his absences and outside business dealings. The Quebec provincial anti-corruption squad investigated him, and laid fraud and money-laundering charges against him and his wife, related to a failed bid to build a super hospital in Montreal. McGill is suing him to get back some of a low-interest $500,000 loaned made to him.

Porter left Canada for the Bahamas in late 2011 when most of the scandals became public. Earlier this spring he announced he was suffering from late-stage lung and liver cancer and was too ill to travel back to Canada to answer fraud allegations. He and his wife were arrested in Panama in May. Mattock was extradited to Montreal and is out on bail. Porter is in jail in Panama, fighting extradition.
