About Leo J. Dillon Professional Corporation

Leo J. Dillon Professional Corporation is a small Toronto firm that focuses only on workplace injury claims. The practice represents injured workers before the Workplace Safety and Insurance Board (WSIB) and the Workplace Safety and Insurance Appeals Tribunal (WSIAT), and it also takes on Canada Pension Plan disability claims. Its office is on the fourth floor of 845 St. Clair Ave. W., on the stretch of St. Clair Avenue West that runs through the Wychwood Heights business strip in midtown Toronto.

Founder Leo J. Dillon holds a B.A., an M.A., and an LL.B., and the Law Society of Ontario has certified Dillon as a Specialist in Workplace Safety and Insurance Law, one of only 12 lawyers in the province with that certification. Dillon has more than 30 years of experience representing injured workers in WSIB matters and, as of March 2020, had appeared in 1,623 WSIAT decisions. The firm represents only workers and says it has never acted for an employer, and its caseload runs from physical injuries and repetitive strain conditions to occupational disease and workplace related mental health claims such as post traumatic stress disorder.
