MISSISSAUGA, Ont. — Residents of Mississauga, Ont. headed to the polls on Monday to elect their next mayor, as the top three contenders offered different visions for the future of the province’s third largest city.

The byelection was triggered after former mayor Bonnie Crombie stepped down in January to lead the Ontario Liberals.

Mayoral candidate Carolyn Parrish, a former city councillor and federal member of Parliament, initially held a wide lead over her opponents in early polling. However, recent polls indicate her lead has declined following her decision to not take part in candidate debates, allowing city councillors Dipika Damerla and Alvin Tedjo to close the gap.
