MacKay says the first file he asked to be briefed on was the Ernest Fenwick MacIntosh case.
The Supreme Court of Canada recently upheld a lower court ruling, quashing all 17 sex offence convictions against the former Port Hawkesbury area businessman.
MacKay says it's too early to say if there will be a federal public inquiry, however.
Former justice minister Rob Nicholson has dismissed the need for an inquiry, saying it would be an expensive and lengthy process that would only give answers to what is already known.
MacKay says he's also been briefed on cyberbullying, an issue that came to the forefront in Nova Scotia with the Rehteah Parsons case.
Her family alleges she was sexually assaulted by four boys and a digital photograph of the incident was passed around her Halifax-area school.
The 17-year-old girl hanged herself in April and was taken off life-support three days later.
