Inside University of Toronto's largest research partnership: McMaster University
Behind University of Toronto's research output sits a defining relationship: 7,660 co-authored works with McMaster University (Canada) in the five years to 2025, the university's single largest collaboration.
It anchors an unusually connected research base: 1,181 collaborating institutions across 81 countries, producing 145,300 joint works over the window, with international co-authors on 47% of output.
The collaborative work travels: its field-weighted citation impact stands at 3.17, where the world average is 1.0.
The Research Collaboration Index, the first global account of how universities actually collaborate, published its first full edition on 15 September 2026. The full results are public.
Every figure derives from the open global research record and is checkable at source.
