When taken as a whole, the McGill campus is more cohesive and appealing. As I noted in my post, I love the old campus (including St. Michael's College) but that does not represent the entire U of T campus. If anything, the old campus accentuates how average other parts of the campus are. McGill is better in this regard as the entire campus is reminiscent of old times as opposed to just certain areas.
Toronto also does not have a streetscape like rue Sherbrooke near McGill. Again, context and symmetry are important. Musée des beaux-arts de Montréal and the Ritz-Carlton do not look out-of-place as the surrounding buildings beautifully complement them (unlike the ROM).
The U of T campus does not have a park comparable to parc du Mont-Royal, which was designed by Olmsted. The fall foliage of Parc du Mont-Royal is unbeatable. The park boasts lovely public spaces, including two belvederes, hiking and skiing trails, a man-made lake, and a sculpture garden. As for views, the grounds of U of T campus do not offer the best view of Toronto’s skyline. The views of Toronto from the campus can’t compete with the panoramic vistas from the top of the mont Royal. On a clear day, one can see as far as mont Saint-Hilaire past downtown Montreal and fleuve Saint-Laurent.
