Obituary of John Gregory O'Neill

It is with deep sorrow and everlasting love that we mourn the passing of John Gregory O’Neill of Unionville on August 28, 2022 at the age of 73. 


John will be dearly missed and forever remembered by his wife Marlene (nee Houser), his children Kale (Jane) and Kier (Jaime), his grandchildren Brady, Fionn, Spencer, Quill, and Lyric, his sisters Jane (Brian), Martha (Ed), Lise (Earle), his sister-in-law Sherry, brother-in-law Barry, his niece Jaz (JR), extended family and dearest friends. He was predeceased by his sisters Helen (Mark) and Colleen (Ron), his Great Aunt Ruth, and parents Margaret and Tom. 


John had a great sense of humor and was often considered to be the life of the party. Lovingly known to his grandsons as “Gampy”, John was a great storyteller, a true raconteur. An avid car enthusiast, John rarely missed an F1 race or qualifier, even when televised in the early hours of the morning, and could be spotted around Unionville driving his beloved black Porsche 951.


Visitation will occur on Thursday, September 1st, from 6:00-8:00 PM at Dixon-Garland Funeral Home, 166 Main Street North, Markham, ON, L3P 1Y3.
