List of Medical groups in Ontario
Ontario has 2,350 medical groups in this dataset, last verified September 9, 2026. That makes it the largest market for medical groups in Canada, with 37% of the national total, ahead of Quebec (1,322).
Among cities, Toronto (113) and Ottawa (110) are nearly level at the top, with Mississauga (102) in third. Together the top three hold only 14% of all medical groups in Ontario, so the market reaches well beyond its biggest cities.
Email reach in Ontario runs above the national rate: 726 medical groups (30.9%) include an email address, against 28.7% across Canada. 2,168 (92.3%) list a phone number, and 704 carry both.
76.5% of medical groups in Ontario have a website, in line with the national average of 75.4%. Only 553 lack a site, so pitch redesigns and SEO rather than first-time builds.
Among the 1,990 rated medical groups in Ontario, 33% hold a 5-star average, in line with the national figure of 32%. 336 are rated 1 to 2 stars (17% of rated businesses, in line with the national 18%), a natural shortlist for reputation management and review software.
