Jack Hastings McMahon

24 May, 193618 February, 2021

It is with great sadness and sorrow that the family of Jack McMahon announces his passing on February 18, 2021 at the age of 84 years old after a long and courageous battle with cancer.

Jack is survived by his loving wife of 62 years, Eleanor; sons Neil (Lisa) in Australia, Doug (Amanda), and Rod (Dina) in Edmonton, and daughter Janelle (Steve Beverly) in Mayerthorpe; ten grandchildren and ten great-grandchildren; and sister-in-law Geraldine (Stan) and family.

Jack had a long and successful career as a Chartered Accountant with Clarkson Gordon and Ernst & Young, and was involved with many boards throughout the years including the Caritas Hospitals Foundation and the Alberta Pension Administration. He served as President of the Institute of Chartered Accountants, and President of the Edmonton Eskimos Football Club.

As an avid golfer, Jack was a long-time member of the Royal Mayfair Golf Club. When he wasn’t golfing he spent his time at the family cabin at Pigeon Lake, travelling around the world with Eleanor, and attending and supporting all of the important events and milestones in his children’s, grandchildren’s, and great-grandchildren’s lives.

Due to Covid restrictions a private service will be held.

The family would like to thank the staff of the Cross Cancer Institute as well as the staff at Shepherd’s Care for their compassion and kindness.

In lieu of flowers a donation can be made to the Cross Cancer Institute or a charity of your choice.

Condolences to Eleanor and family. Bev and I are so sorry to hear of Jack’s passing.

I joined Clarkson Gordon as Jack’s Manager in 1984. We had an eclectic and diverse staff that worked hard and enjoyed celebrating those work achievements. Jack was mostly a supportive participant though I do have memories of him scratching his head over a few of our choices. I was appointed a Partner in 1987 which wouldn’t have been possible without Jack’s significant support. I am forever grateful!

Jack was highly regarded for his distinguished professional career, his community service, his golf prowess and his loyalty to friends and colleagues. What we admire most was his love and dedication to Eleanor and the children and grandchildren. Truly a great family man!

Vikki and I are so sorry to hear of Jack’s passing.

He was the best partner anyone could hope for.

His efforts even continued after retirement. He nudged the Alberta Chartered Accountants to award me a Distinguish Service Award in 1998 for my efforts in developing the business plan for the Winspear Centre

Our very best to Elenor and family

Jack was a true gentleman and professional. I am proud to have been one of his partners and Jack was always supportive when I needed his assistance. He truly was a Clarkson Gordon man. Our thoughts are with you Eleanor and your family.

Jack was a partner back in 1991 when I started with Ernst & Young (Clarkson Gordon) right out of university. Jack had a huge impact in my development during my early days in the profession. Jack was always a “larger than life” character with a sparkle in his eye. He had a real zest for life and often joked with me that, post retirement, he was shooting his “age” at the Mayfair. He will be missed.

Condolences to Eleanor and family on their loss of a much admired man who was full of integrity and self giving. Doug articled with Jack at Clarkson Gordon and later on Eleanor volunteered at the Cross with Diane. Perhaps Jack and Doug will share old times in their place of rest.

Very sorry for your loss. He was a wonderful person and we will cherish many fond memories of him.
I served at similar times with Jack on the CA Board and the Caritas Hospital Foundation and of course in the poker group. He was always a strong participant and leader and had a great interest in making our community a better place.
I also especially enjoyed him at our poker nights where his friendly personality came through and his humour and good fellowship were always evident.
He will be sorely missed. God bless him!
