DEITNER, Ronald Joseph Deitner

Passed away peacefully with his beloved wife by his side on Sunday, February 1, 2026, at Waterloo Regional Health Network – Queen’s Campus, Kitchener (formerly St. Mary’s General Hospital).

Ron was born on August 11, 1949, in Brussels, Ontario, alongside his twin brother, the seventh child of the late Charles and Josephine (Weber) Deitner.

Beloved husband of Mary (Mantler) Deitner, whom he married on June 1, 1974. Cherished father of Graham Deitner, Mark Deitner (Saida Tesfai), Drew Deitner (Samantha), and Heather Murray (Jason). Proud and devoted grandfather to Nora, Vienna, Hudson, Jack, Connor, Anderson, and Adelaide.

Ron will be deeply missed by his siblings Marjorie Bolger, Ruthann (Karl) Gmach, Marlene (Bill) Henhoeffer, Rosemary (Jim) Trznadel, Donald (Joan) Deitner, and Betty (Mike) Nafziger; by his sister-in-law Pat Deitner; by many nieces and nephews; and by the extended Mantler family.

Predeceased by his sister Pat Orlowski; brothers Raymond (Pat) Deitner and Ken Deitner; and by his brother-in-law Stan Bolger.

Ron was proudly part of a true twin legacy—a twin himself, an uncle of twins, a grandfather of twins, and a great-uncle of twins, with 8 sets of twins total.

A lifelong member of the Wilmot Township community, Ron was a well-known dairy farmer and later operated a hobby farm filled with geese, chickens, cows, pheasants, and a well-loved garden. Many locals fondly remember stopping at his roadside produce stand, “Corn and More.”

Ron gave over 30 years of dedicated service to the Spirit 83 and the New Hamburg Firebirds Hockey Association. Following a serious farm accident that resulted in the loss of his leg, Ron never slowed down becoming a tester for new prosthetic designs to ensure they could withstand his determination and drive. He proudly served as Wilmot Township’s first dog catcher with one leg, keeping the first dog he caught when no one came to claim it. He also worked as a night watchman with one leg at the fall fair, theatre, and local events, ensuring everything and everyone remained safe.

Relatives and friends are welcome to visit with the family on Monday, February 9, 2026, from 2:00 – 4:00 p.m. and 6:00 – 8:00 p.m. at the Mark Jutzi Funeral Home, 291 Huron Street, New Hamburg. A Memorial Mass will be held at Blessed Sacrament Parish on Tuesday, February 10, 2026, at 11:00 a.m.

As expressions of sympathy, memorial donations may be made to the Baden Volunteer Fire Department (for equipment costs) or the New Hamburg Firebirds Hockey Association. Donations may be arranged through the funeral home website.

If you are unable to make a monetary donation, the family asks that you consider becoming a blood donor in Ron’s honour. Ron was a passionate advocate for blood donation and proudly donated 100 units himself during his lifetime.

Ron’s legacy is one of resilience, generosity, service, and unwavering determination, qualities that will be remembered by all who knew him.
