Born in 1977 as Jennifer Gray in East York, Ontario, McKelvie spent her early years in an apartment complex on the North York-Scarborough border.

McKelvie pursued higher education at the University of Toronto Scarborough, earning a Bachelor of Science in Environmental Science. She continued her studies at the University of Toronto, obtaining a Master of Science and a Doctor of Philosophy in geology, specializing in geochemistry, environmental remediation, and biochemistry. Her academic mentor and supervisor was Barbara Sherwood Lollar, a renowned geochemist. McKelvie’s research was recognized and supported by prestigious awards, including the L’Oréal UNESCO Women in Science Fellowship and the Natural Sciences and Engineering Research Council of Canada.

Her career in environmental science led her to work with the Nuclear Waste Management Organization and the Canadian Institute for Advanced Research, where she managed research partnerships focused on sustainability and infrastructure planning. Her expertise in environmental policy positioned her as a respected voice in municipal governance.

McKelvie’s political career began at the municipal level when she was elected as the Toronto City Councillor for Ward 25 Scarborough—Rouge Park in 2018. She was re-elected in 2022 and was appointed Deputy Mayor of Toronto, representing Scarborough.
