The numbers tell only part of the story. The CIHI data exclude Quebec hospitals as well as surgeries performed in private clinics like the McLean Clinic in Mississauga, which describes its surgeons as “industry pioneers” for top surgery — mastectomies and breast reductions in those assigned female at birth, and breast augmentation for those born male transitioning to female.

One specialist in transgender health issues said that, when applying for OHIP funding for people seeking top surgery, “50 to 70 per cent will go to McLean.”

The percentage dipped last year as hospitals grappled with pandemic-driven surgical backlogs. “But the private clinics just kept churning them through,” said one doctor familiar with trans medicine who requested anonymity fearing professional repercussions.
