The University of Toronto has been named one of the top five universities in the world - and the No. 1 university in Canada - for research impact, according to the 2025 edition of the NTU World University Rankings .
In this year's ranking, U of T placed fourth globally behind Harvard University, Stanford University and University College London.
Among public universities, U of T ranked second worldwide and was the top public university in North America.
"This ranking reflects the University of Toronto's world-leading strength in generating new discoveries and knowledge that are making an impact in Canada and around the globe," said Leah Cowen, U of T's vice-president, research and innovation, and strategic initiatives.
"It's also a testament to the talent and dedication of our diverse community of researchers - faculty, staff, students, librarians and post-docs - who are pushing boundaries across a wide range fields every single day."
The NTU ranking evaluates universities based on eight indicators that measure research productivity, research impact and research excellence. These include the number of articles published, citation counts, average citations, highly cited papers and the number of articles in high-impact journals.
This year, NTU considered more than 2,000 universities and ranked the top 1,200.
In addition to the overall standings, NTU released two supplementary sets of rankings: one covering six broad academic fields and another detailing 27 narrower subject areas.
U of T ranked among the top 50 globally in four of the six broad subjects and first in Canada in each of those four fields: medicine (second globally); social sciences (fourth); life sciences (12th); and natural sciences (29th).
At the subject level, U of T was among the top 50 globally in 12 of the 27 subject areas - and ranked first in Canada in 16 of them.
It also ranked in the global top 10 in five subjects. They are: clinical medicine (second); neurosciences and behaviour (third); social sciences, general (fourth); psychiatry and psychology (fourth); and biology and biochemistry (ninth).
Three other Canadian universities were also featured in the top 100 of the main NTU ranking: the University of British Columbia (33rd), McGill University (50th) and the University of Alberta (88th).
Overall, U of T continues to be ranked among the top 30 universities globally across the five most closely watched international rankings: QS World University Rankings, U.S. News & World Report's Best Global Universities, Times Higher Education's World University Rankings, ShanghaiRanking Consultancy's Academic Ranking of World Universities and NTU World University Rankings.
