Mr. Sammon holds an LL.B (cum laude) and LL.M from the University of Ottawa and was called to the Ontario Bar in 1976. From his call to approximately 1994, his practice was largely restricted to family law and civil litigation.

Over his years of practice, Mr. Sammon has conducted hundreds of contested proceedings and has had numerous reported and unreported decisions. He has appeared at all levels of Court, including the Supreme Court of Canada, where he has been counsel in a number of cases dealing with rights of the unborn, mercy killing, religious freedom, division of pensions on marriage breakdown and partial termination of a pension fund, vicarious liability, suability of the Roman Catholic Church, patenting of higher life forms, same sex marriage, and the division of powers in relation to the Assisted Human Reproduction Act. He is or has been involved in a number of class actions dealing with pension surplus rights, prisoners’ rights, Indian residential school litigation, pay day loans and manufacturer’s liability. He has also defended institutional clients in sexual abuse claims in Newfoundland, Labrador, Ontario and British Columbia.

Mr. Sammon is the author of Advocacy in Child Welfare Cases: A Practitioner’s Guide, Carswell, 1985, as well as other publications and has taught advocacy at the Bar Admission Course in Ottawa.
