Gilles Loiselle, Canadian politician and diplomat, 33rd Canadian Minister of Finance
Gilles Loiselle, (born May 20, 1929 in Ville-Marie, Quebec) is a Canadian retired politician.

Loiselle was the correspondent for CBC News in Paris for a decade before being appointed the government of Quebec's agent-general in the United Kingdom in 1977. He represented Quebec to the British government when the federal government of Canada was negotiating the Patriation of the Constitution of Canada from Britain in the 1980s.

After being elected to the House of Commons of Canada in the 1988 federal election, Loiselle joined the cabinet of Brian Mulroney. In 1990, he was elevated to the post of President of the Treasury Board and, in 1993, he served as Minister of Finance in the short-lived government of Kim Campbell.

Loiselle, a Progressive Conservative, was defeated in the 1993 election. The Tories were cut down to two seats, and Loiselle himself was held to third place.
