Tracey brings more than 25 years of progressive leadership experience in Ontario's health care system, including senior roles at University Health Network and the Centre for Addiction and Mental Health, where she previously served as President and CEO. At HHS, one of Canada's leading academic and research hospitals, Tracey has been instrumental in driving quality improvement, patient and workforce safety, and embedding equity, diversity and inclusion across the organization.

This integration takes effect November 1, 2025.
"Hamilton Health Sciences has been a partner in building Ontario's critical care transport system from the beginning, working closely with Ornge to connect patients across the province with the specialized care they need," says MacArthur.
