MacKay ordered the review last month, saying the sexual abuse case has concerned him for years.
Earlier this year, the Supreme Court of Canada upheld a lower court ruling that threw out 17 sexual abuse convictions against MacIntosh because the case took too long to get to trial.
The review was launched to examine the process to extradite MacIntosh and the issues surrounding his passport and border control.
MacIntosh was in India working as a consultant when the sex abuse allegations first surfaced in Nova Scotia in 1995.
But he wasn't extradited to Canada until 2007 and his first trial didn't start until 2010.
MacIntosh's passport was renewed in 1997 and in 2002, despite the fact he faced outstanding charges and a warrant had been issued for his arrest.
Passport Canada said in July that it has revised its policies as a result of the case.
