I think the three best universities in Canada usually refer to the University of Toronto, McGill University and the University of British Columbia (UBC).

The University of British Columbia (UBC) is the pearl of the west coast, and Vancouver Campus is known as the most beautiful campus in North America. The University of Toronto is a top university in Canada with high scientific research level, large scale and strong faculty. McGill University is a top institution of higher learning in Canada, with a strong humanistic atmosphere, the highest proportion of doctoral students in the country, and the largest number of Nobel Prize winners and Rhodes scholars.
