Prior to being elected, Smith served in both Federal and Provincial Public Services for ten years. She has a Bachelor of Arts in Sociology and Psychology from Dalhousie University, and a Master of Arts in Sociology from Carleton University. Whilst on the council, she was seen as being left wing. She ran for mayor in 1991, losing to Jacquelin Holzman by just over 3,000 votes.
Since her defeat, Smith has served as the chair of the Ontario Housing Corporation, served on the Ontario Municipal Board, was an associate for MAXGROUP Associates, and since 1999 she has owned her own consulting business.
