After the
National Post published revelations about his business dealings with international lobbyists and close ties to the president of
Sierra Leone, Porter resigned as chairman of the Security Intelligence Review Committee in November 2011, Porter's questionable business dealings and foreign connections included his relationship with
Ari Ben-Menashe, a Montreal-based businessman and an ex-Israeli international lobbyist and arms dealer, who was arrested and charged in the United States for illegally attempting to sell military transport airplanes to
Iran. Among the suspicious activities reported by the
National Post were revelations that Porter had received $22.5 million in consulting fees from
SNC-Lavalin prior to awarding the firm a $1.3 billion contract related to the construction of the McGill University Health Centre. These dealings were found to be in violation of the
Quebec Health Act, and along with the emergence of other questionable business activities, led to calls for his resignation. The hospital's board of directors initially came out in support of Porter, but he voluntarily resigned on December 5, 2011 in light of mounting media and public pressure. In November 2012,
McGill University filed a lawsuit seeking repayment of $317,154 (~$ in ) which he owed the university. The lawsuit indicated that Porter responded to a letter of October 2012 (demanding payment of the outstanding amount within one week) only with a three-line email, and that they had not heard from him since then. Following the controversy over the unpaid loans, McGill University described Porter as "of unknown address", with McGill's suit indicating that he gave his current addresses as post office boxes in the
Bahamas and in Sierra Leone. It also gave a link to a story in the
Turks and Caicos Magazine, which refers to his establishing cancer centres both in the Turks and Caicos and Bahamas in conjunction with his long-time friend and business partner
Karol Sikora, who is Director of Medical Oncology at the Bahamas Cancer Centre, in addition to their mutual cancer-business interests in the British Isles. == Criminal charges and arrest ==
