After 36 years at the helm, 93-year-old Hazel McCallion will be honoured by city manager Janice Baker and other prominent community members for her service.
Retiring city councillors Katie Mahoney and Pat Mullin will also be honoured at the meeting, which begins at 9 a.m.
McCallion will officially pass the reigns to mayor-elect Bonnie Crombie on Dec. 2
Elected in 1978, McCallion oversaw immense growth in Mississauga over her 12 terms in office. Her longevity and ability to get projects completed earned her the nickname 'Hurrican Hazel.'
She publicly supported Crombie in the hard-fought October civic election.
She told media during the campaign that while she will no longer sit in the mayor's chair, she has no plans to disappear from Mississauga's political scene.
