As the statutory deputy mayor, McKelvie assumed certain mayoral powers following the resignation of John Tory on February 17, 2023, and remained the highest-ranking official in the city until the swearing-in of Olivia Chow as mayor on July 12, 2023, following the 2023 Toronto mayoral by-election. Under Chow, McKelvie continued in her role as deputy mayor, serving in an honorary capacity and representing Scarborough. She resigned as a city councillor after her election as an MP in May 2025.

For almost a decade, she served as a senior scientist at the Nuclear Waste Management Organization, and as a research director at the Canadian Institute for Advanced Research. She was registered as a Professional Geoscientist (P. Geo) with the Association of Professional Geoscientists of Ontario.

In both of these capacities she fought for renewal and investment in Scarborough.

Political career

Toronto City Council McKelvie was Chair of Toronto's Infrastructure and Environment Committee. She also served on Scarborough's Community Council, the Toronto Hydro Corporation Board of Directors and as the chair of the Toronto Zoo Board of Management. Enhancing public transit, protecting the environment and creating employment opportunities in Scarborough, were her key electoral priorities. She also derided the post-amalgamation shift of public investment and municipal jobs out of Scarborough to Toronto's downtown core.

Following the resignation of John Tory on February 17, 2023, McKelvie assumed certain powers of the mayor of Toronto until Mayor Olivia Chow took office on July 12, following the 2023 mayoral by-election.
