David Joseph McGuinty (born February 25, 1960) is a Canadian lawyer and politician who has been the minister of public safety since December 2024.

He was chosen to serve as president and chief executive officer (CEO) of the Prime Minister's National Round Table on the Environment and the Economy, a government think-tank concerned with sustainable development.

[1][2] While not invited to join Paul Martin's Cabinet, McGuinty served on the House of Commons Standing Committee on the Environment and Sustainable Development.

[4] On May 30, 2006, interim Liberal leader Bill Graham appointed McGuinty as the Official Opposition critic for Transport.

[16] On November 20, 2012, following a meeting of the Natural Resources Committee, McGuinty stated, among other things, that Conservative MPs were "shilling" for the oil and gas industry, did not belong in the national legislature, and should "go back to Alberta.

"[18] Interim leader Bob Rae apologized on behalf of the Liberal Party and said McGuinty was away on family business for the following week.

However, he took issue that much of the attention was focused on the revelations that some MPs worked with foreign governments and not other aspects of interference like the media.

[26] Following a cabinet shuffle, McGuinty was appointed Minister of Public Safety in the 29th Canadian Ministry on December 20, 2024.
