It is with heavy hearts that we announce Mark passed peacefully at his home on Friday February 13, 2026, and joined his parents Don and Shirley, brother Guy, and best friend Royce in heaven.
Mark, lovingly referred to as ‘Uncle Buck,’ grew up on two family farms in Grafton. He attended Grafton Public School and CCI East before joining the Sheet Metal Union and working for Stark Mechanical. Mark suffered his first of many hip replacements at twenty years of age which contributed to an early retirement, at this time his role of Uncle Buck truly evolved and he became keeper of all family pets.
Uncle Buck was always ready for the next adventure and had a way of writing them into his sometimes unbelievable but always memorable stories. He and his tales had the ability to make anyone laugh, regardless of circumstance or environment. Mark was intentional and spiritual. His premonitions were frequent and often on the mark.
Mark loved his family, friends, and some of the most vulnerable in our community. He was the happiest when helping others, and will always be remembered for his compassion, whether it be volunteering with Dave Alexander at the Cobourg Salvation Army, leading Saturday night AA groups, or helping a neighbour. Mark would show up to the best of his abilities.
Uncle Buck, thank you for always being the life of the party, living life on your own terms, and making those around you feel seen.
Mark is predeceased by his parents Don and Shirley McQuaig, brother Guy McQuaig, and his very best friend Royce. He is lovingly remembered by sister’s Chere (Scott Campbell), Vicki (Terry Irwin), and sister-in-law Darlene Gabovic. He will be greatly missed by Charrissa (Mike), Jeremy (Kara), Darcy, Jamie (Sarah), Tyler (Chantal), Caeleb, Toia (Geoff), Sophie, and Chanel. Uncle Buck was made ‘Great’ by Mcquaig, Max, Morgan, Keilley, Dawson, Ella, George, Ruby, Lincoln, Miller and Wrenly.
Forever thankful for his chosen brothers Ed Kowalczyk, Charlie Black, and Derek Redick.
In lieu of flowers, those wishing to honour Mark are asked to make a donation to the Cobourg Salvation Army.
The family invites friends to celebrate Mark’s life on Sunday, March 22nd, at the Royal Canadian Legion Branch 580 Grafton from 11:00am-2:00pm. Nieces and Nephews will share memories at 12:00 and all others are welcome for an “Open Mic” to shares stories of Mark.

Truly sorry to hear that Mark is gone. I got to know ( Buck ) through my friend Scotty and spend time together going to the Lakefield Chiefs hockey games. Mark’s humour always made me laugh. The last message I got from him was that he had lost his best friend Royce , he sure did love that little dog. R.I.P.
Sending the McQuaig, Campbell and Irwin families our deepest condolences, love and prayers at this difficult time. Love Dani, Matt and kids
My sympathy and condolences to the family. As I have felt the emptiness Marks loss has brought to my life I can confidently say he was one of my best friends. He was always there for me and wouldn't think twice to tell me what I needed to do even if it wasn't what I wanted to hear. Even though we didnt get to share that last weekend we were so looking forward to I will remember all of our good times. We had alot of good times, We laughed alot, thats what I will miss the most . I miss you so much already ❤️ T
My deepest condolences to Marks Family. My thoughts and prayers are with you at this time of loss. I have many fond memories of playing hockey, fishing at the creek , and roaming the country side with Mark.
Dear Chere, Vicki and Darlene, Despite all of Mark's surgeries and constant pain Mark greeted you with his smile. We met Mark shortly after Guy and Darlene were married, around 12 years old. It was always a pleasure to bump into him. Deepest sympathy to all of his family and friends. Mary and Ivan Elder
So sorry for your loss Such a beautiful tribute, as I remember Mark for his great sense of humour and contagious laugh Condolences to you all
We are very sorry to hear of Mark's passing. Mark was a loving of life type of person and will be greatly missed. Our condolences to all the family
So sorry to hear of Mark’s passing. It was always fun to work with him, please accept my condolences.
I appreciated Mark whenever we got together. We connected through TSA (The Salvation Army) and participated in recovery programs and Bible studies. Mark used to walk his dog Royce to the TSA and we would invite the two of them in through the back door normally because it was after hours. We'd chat a bit and Royce would gobble up a few treats. Mark and Royce were great company for each other. I will certainly miss him, he was a likeable guy, it is just sad that he died so young. I hope and pray he knew Jesus and he is with him now.
Vicki, Chere and family - I am so sorry to hear about Uncle Mark - my deepest condolences. I will always remember him visiting me at the pharmacy - he was one of the funniest and sweetest people. Rhi
RIP Mark
Vicki and Chere , I am so sorry to hear of Mark's passing. Thinking of you. Halle
