In Loving Memory of Justin David Guay
March 14, 1974 – June 21, 2026
It is with profound sadness that we announce the passing of Justin David Guay of Kitchener, Ontario, on June 21, 2026, at the age of 52.
Born in Brampton, Ontario, on March 14, 1974, Justin lived a life defined by his love for family, his passion for the outdoors, and his appreciation for life’s simple pleasures.
Justin will be lovingly remembered by his daughter, Mackenzie (Kyle); his mother, Mary Lynne (John); his sister, Michelle (Daniel), his niece and nephew, as well as his aunts and uncles. He will be remembered for his fierce loyalty, kind heart, quick wit, and the belief he often shared: “Nothing changes if nothing changes.” Above all, he will be remembered for the countless memories and laughter he created with those he loved. He was predeceased by his father, John, whom he loved deeply and missed every day.
Justin’s greatest joy was being Mackenzie’s dad. She was the light of his life, and he was incredibly proud of the person she has become. He treasured every moment they spent together—from sharing laughs and attending concerts to simply enjoying each other’s company. His love and unwavering support for her never faltered.
Justin found peace and happiness on the water with a fishing rod in hand. He loved sharing his passion for fishing with Mackenzie and other family members, patiently teaching them the tricks of the trade and the simple joy of waiting for a fish to bite.
A devoted sports fan, Justin rarely missed an opportunity to cheer on the New York Giants, the Toronto Blue Jays, and the Kitchener Rangers. He was also an avid music lover with an appreciation for every genre. Some of his happiest moments were spent attending concerts or enjoying live music with Mackenzie, family, and friends.
Justin had a gift for storytelling and an incredible sense of humor that could brighten any room. Whether sharing old memories, telling a funny story, or making someone laugh when they needed it most, he had a way of making everyone around him feel welcomed, valued, and at ease.
Although his time with us was far too short, Justin leaves behind a legacy of love, loyalty, laughter, and unforgettable memories. He will be deeply missed, forever loved, and never forgotten.
“I’ll see you down the road somewhere.”
“No dress rehearsal, this is our life.”



I remember Justin as always learning new things . He had a background in law, negotiations, and labour. Always upgrading till he finally got the job he wanted. He worked hard when he could although his heart and living with cancer were his biggest challenge. He fought the good fight till the end. Looking forward to work and daily life till his heart took him to his dad. Now you can rest in peace Justin. Say hi to in the ditch John for us.
People like Justin made the world a much better place. His love for family and his compassion for animals made a difference in the world. We will always be greatful for his help in training a dog that we had. Thank you Justin.
I am so sorry to hear of Justin’s sudden passing. I know how deeply he was loved and how greatly he will be missed. I hope the many precious memories you shared with him will bring comfort and help fill, in some small way, the immense void left in the hearts of his daughter, Makenzie, his mother, Mary Lynne, his sister, Michelle, and all who knew and loved him. My thoughts are with you during this incredibly difficult time.
My deepest condolences to Justin’s family and friends.
Justin was an amazing person and a great friend. Whether it was at a concert or at work, Justin always found a way to make it more enjoyable. My deepest condolences to Justin’s family during this time
Justin, I am going to miss you so much. Even though you were taller than me before you turned 14 (which was your goal), you will always be my baby brother.
I will hold the memories of us rolling down the hill at the cottage, taking our kids to Disney on Ice, hiding from and scaring the babysitters, and you trying to put a gas fire out in my backyard with a water hose close always.
I will forever miss your laugh, your entertaining stories, the way you loved my kids, and your huge soft spot for your animals. Most of all, I just miss you.
I’ve been picking up the dimes you’ve been sending, and thought that the 2 of you knocking the “WE” off my welcome sign was a pretty good one. Say Hi to Dad for me and keep stopping in from time to time.
I love you ugly, from uglier 💙
I didn’t know my nephew Justin well as my employment took me to the other side of the country. However I did hear news about Justin and Mackenzie each time I spoke with his mother / my sister Mary Lynne. What I did come to know was that most important to Justin was his role as a single parent. Justin loved his daughter Mackenzie with everything he had and always placed her and their relationship as the number one priority in his life. Make him proud Mackenzie and know that he will forever be watching out for you and he will always have your back. Sadly, I never got to meet with Justin over a pool table, I understand he was pretty good. So was his father John, I’m certain they will engage in a few friendly games together. Say hi to John for me Justin, as you, I loved him dearly. Uncle Mike
Uncle Justin, I’m going to miss all of your hilarious stories so much, It was never a dull moment when you were around. I’ll always cherish our time out on the lake when you’d take us fishing. Even though I never caught anything bigger than a crappie, I always had the best time out on the water with you. Those are memories I’ll hold onto forever. Say hi to Grandpa for me
