Security Intelligence Review Committee
The Security Intelligence Review Committee (SIRC; ) was a committee of Privy Councillors that was empowered to serve as an independent oversight and review body for the operations of the Canadian Security Intelligence Service (CSIS). SIRC was established in 1984 as a result of the reorganization of Canadian intelligence agencies recommended by the McDonald Commission investigating the illegal activities of the former RCMP Security Service.

SIRC's role was to review the activities of CSIS to ensure that the extraordinary powers granted to the security service are "used legally and appropriately, in order to protect Canadians’ rights and freedoms." SIRC did not report to a minister but rather reported directly to the Parliament of Canada. 

On July 19, 2019, SIRC was superseded by the National Security and Intelligence Review Agency (NSIRA), a super-agency mandated to review all Government of Canada national security and intelligence activities.

Controversies
Some appointed members of the Security Intelligence Review Committee had been at the center of controversies related to their activities outside the Committee.
Wesley Wark, visiting professor at the University of Ottawa’s Graduate School of Public and International Affairs, together with Ronald Deibert, professor of Political Science, and Director of the Canada Centre for Global Security Studies and the Citizen Lab at the Munk School of Global Affairs at the University of Toronto, have both been important voices in calling for the need to enhance oversight and review of the Canadian Security Services watchdogs due to its current inefficiency.
Authors Reg Whitaker and Anthony Stuart Farson, both experts in National Security, suggest that there is a need to enhance the role of Parliament in the accountability process and enhanced review and oversight bodies.

Chuck Strahl (2012–2014) lobbying activities
In January 2014, Chuck Strahl resigned his position as chair of the Security Intelligence Review Committee, the watchdog of Canada’s spy agency, after it was revealed by the press that he is also registered as a lobbyist over the Enbridge Northern Gateway Pipelines.

Arthur Porter (2008–2011) criminal charges and arrest
Arthur Porter and his wife Pamela Mattock Porter were detained by Interpol agents in Panama on May 27, 2013, after an investigation by the Sureté du Québec, the Royal Canadian Mounted Police and the International Criminal Police Organization (Interpol). He faces charges in Canada of fraud, conspiracy to commit government fraud, abuse of trust, secret commissions and laundering the proceeds of a crime.

The fraud against the Quebec government is related to his alleged role in the handling of a $1.3-billion Montreal hospital construction and maintenance contract.
At the time of the alleged fraud, from 2008 to 2011, Porter director general of the McGill University Health Centre in Montreal, Quebec, being in charge of one of Canada’s largest health-care providers. He was appointed to the position in 2004. He was also a member of Air Canada’s board of directors.

Porter claimed diplomatic immunity on the basis that he was travelling via Panama on a diplomatic mission to Antigua and Barbuda, on behalf of the government of Sierra Leone, according to his lawyer Ricardo Bilonick Paredes (formerly known as Ricardo Bilonick), a convicted cocaine smuggler with ties to Panama's former dictator, Manuel Noriega and Colombian drug cartels. However, the Sierra Leone government says he is a goodwill ambassador and thus has no diplomatic immunity.

Air India bombing
In 2005, SIRC came under criticism for allegedly not giving close enough scrutiny to the activities of CSIS regarding the Air India bombing, where crucial wiretap evidence was destroyed putting the legal case against the alleged Air India bombers into jeopardy. 
The Security Intelligence Review Committee cleared CSIS of any wrongdoing. The report remains secret to this day.
