Gary Vincent Lunn PC (born May 8, 1957) is a retired Canadian member of Parliament for the British Columbia riding of Saanich—Gulf Islands.

In April 2001, Lunn was one of the first Alliance MPs to openly criticize the leadership of Stockwell Day, and was suspended from caucus in May of the same year as a result.

Keen, who was due to appear before a parliamentary committee the next day, had ordered a shutdown of the NRU reactor at Chalk River, Ontario, which is operated by Atomic Energy of Canada Limited, in November 2007 over the AECL's failure to perform safety upgrades.

[citation needed] Appearing before a parliamentary committee January 16, 2008, Lunn refused to cite one example of what Linda Keen had done wrong in her job, only that she had lost the confidence of the government.

"These are the kinds of Republican tactics this town has never seen before," Liberal MP David McGuinty (Ottawa South) told the natural resources committee.
