JOHN JOSEPH "JACK" QUINN obituary

JOHN QUINN Obituary

Jack, devoted husband and father, passed away peacefully on September 8, 2025, at his beloved farm at the age of 76. He is survived by his wife, Barbara, of 54 years; his three children, John (Jodi), Kate (Alex), and Lewis Michael (Margo); his grandchildren, Jack, Clare, Hugo, and Cora; and his sisters, Elizabeth Quail and Jane Childers. Jack grew up in Indiana, where he met and fell in love with Barbara. Jack went on to do his undergraduate studies at George Washington University before completing law degrees at Indiana University and Yale. In 1976, he and Barbara immigrated to Canada, where he taught law at the University of Western Ontario, Osgoode Hall and as a visiting professor at Georgetown University. Jack later entered private practice specializing in competition law at Blake, Cassels and Graydon. Following a successful career, he took early retirement to spend time on his farm. Jack loved discussing politics and economics, exploring the outdoors and spending time with family and friends from all walks of life. He possessed a fierce intellect and always took pride in his numerous academic and professional accomplishments. However, he was proudest of the life he and Barb built for their family. His children and grandchildren are his true legacy. He will be dearly missed. A Ceremony of Life to be held at Mount Pleasant Funeral Centre on October 18th from 2:00 – 4:00 p.m. In lieu of flowers, donations to The Nature Conservancy of Canada are sincerely appreciated.

Jack was one of my earliest close father figures as he and my dad were colleagues and Mike was a best friend of mine since we were babies. Jack was one of the funniest people I´ve ever met. It was always a joy to spend time with him and the Quinn family. He made the world a better place being a prolific professional in his field and a dedicated, active father and husband. He was brilliant and salt of the Earth relatable and humble. His wit was supreme and his calm demeanour a salve in this crazy world. I loved him and always will. God bless him and his family. We love you, Jack.

I had the honour and pleasure to work closely with Jack when I worked as in-house counsel. He was always interested in the deep details of the transactions and had a wonderfully kind way about him. My condolences to his family and friends. The world needs more Jack Quinn´s.

Jack was my legal writing and moot court professor in first year law at Western. I later took competition law from him and we were colleagues at Blakes for a while. For certain, Jack was a highly intelligent man, but more importantly than that, he cared for his students. He will be missed. My condolences to his family.
