Hazel McCallion, was a Canadian businesswoman and politician who served as the fifth mayor of Mississauga, Ontario, from 1978 until 2014.

She was first elected in November 1978, and is the longest -serving mayor in the city's history, having served for 36 years at the time of her retirement in 2014. She was a successful candidate in twelve municipal elections, having been acclaimed twice and re-elected ten other times. Her supporters gave her the nickname "Hurricane Hazel" because of her outspoken political style with reference to the Hurricane of 1954, which had a considerable impact.

After graduating from Quebec High School, she attended business secretarial school in Quebec City and Montreal. She stated that she would have wanted to attend university, but her family could not afford it. After beginning her career in Montreal with the Canadian Kellogg company, she was transferred to Toronto in 1942, where she helped set up the local office. McCallion left the business world in 1967 to devote her life to a career in politics. As a volunteer, McCallion also served as president of the Anglican Young People's Association of Canada, and later, provided leadership as a district commissioner with the Girl Guides of Canada in the early 1960s.

Hazel McCallion lived an amazing life devoted to public service working well into her 90’s. In the end she died from pancreatic cancer at her home on January 29, 2023, at the age of 101.

She was an inspiration to so many people and we hope she is at peace “In Heaven with the Stars.”
