CLARK, Brett William

November 21, 1988 – July 12, 2023

It is with heavy hearts that we announce the passing of Brett William Clark, 34 years young, on July 12, 2023. A tragic vehicle collision in British Columbia claimed the lives of Brett, his loving partner, Katy Sully, and their dog, Tina. Brett will be truly missed by his parents and brother, Jon, Julie (née Onofrychuk), and Connor Clark (Emma Locke). 

Brett was born in Vancouver BC, on Nov 21,1988. From a young age he loved the outdoors and spent summers camping, backpacking with his mom and brother and fishing on the Bow River behind their house in Cochrane, Alberta. In the winters, he spent hours ice fishing. His passion of geology, stemming from a bone digging kit as a young child, brought him to Drumheller as an adult. He worked at the Royal Tyrell Museum for several seasons, allowing him to expand his rock and fossil collection exponentially. Brett was always eager to share his knowledge of geology with others. Whether on the trails or under the microscope, he inspired interest in friends and young cousins. 

After graduating from the French Immersion program at Cochrane High School, he went on to study Earth Sciences at the University of Calgary. During university, Brett began Brazilian Jiu-Jitsu with his brother, Connor. He trained and competed for over a decade, and was an integral part of the martial arts community in Cochrane.

Most recently, Brett lived in downtown Calgary with his loving partner, Katy, and American Husky, Tina. Brett could be found roller blading behind Tina many nights of the week.

A service will be held in memory of his life Sunday, July 30, 2023 at 1:00pm at the Cochrane RancheHouse, 101 RancheHouse Rd, Cochrane, AB T4C 2K8. Donations can be made in his honour to Diabetes Canada at

    ❤️❤️❤️❤️ My very dear friend, I am so devastated by Bret’s and Katy’s and Tina’s their dog accident and their passing. My heart, my tears, my sympathy, my condolences and my love is with you Julie, John, Connor and Emma and your family. I remember many, many summers spent together with our boys at French Camp and Shuswap. I remember all the preparations for the camp and the driving, cooking, setting up the camp, feeding camp councillors and most of all the amazing fun we had together. I am so sorry this has happened to Bret and his lady. Bret was such nice man and I new him since he was a young boy. I pray for them and ask God to welcome them to his kingdom and give them a beautiful wedding to celebrate their love for each other. I am here for you my friend anytime you need me, please remember this.
    I will come to say my goodbyes to Bret on July 30th. ❤️❤️❤️❤️

    Julie, John and Connor,
    I don’t have words to fully express just how sorry I am to know of the sudden and tragic passing of Brett. I want you to know that you are not in this alone and that I am here to help and be a support whenever you need it. Even though I never had the opportunity to meet Brett, I share in your sadness. After reading the tribute and glancing through the above outdoor adventure photos, I can tell that he was a remarkable young man raised in a very close, loving family. Brett has such a wonderful smile and a happy disposition and this quote seems fitting: “There are some who bring a light so great to the world that even after they have gone, the light remains.”

    Julie, Jon, and Connor,

    We are so sorry for your loss. Knowing Brett for the past 15 years has been one of the greatest honours one can have. Brett made a lasting impression on everyone he met, cared deeply for his friends and always took the time to have a vested interest in peoples lives. Brett had the greatest zest for life. He was so passionate in everything he did, whether it be educating us on geological formations during our hikes (so grateful to have been able to do Flow lake with him), teaching us how to ice fish (old school – with a manual auger), or just having a slow float down the elbow River (even if he caught a shoe instead of a fish the effort was always there). The world won’t be the same without Brett and we will miss him deeply.

    Jon, Julie and Connor I am so sorry to hear this news. Though Brett and I didn’t keep I’m touch much since High School I always remembered how great a friend he was. I look back fondly on our time in Riverview and I can’t imagine how you are feeling. My love and well wishes to you all during this time, Brett was a shining star and the world will miss him.

    Julie,Jon & Connor,

    I never had the honour of meeting Brett, yet I have spent quite a bit of time with Julie over the years. Anyone with such a energetic, caring & loving mother has definitely known what it is like to be loved and to live. Thats one of the most important things in this life. My heart feels deeply for you all.

  14. On July 21, 2023 at 1:28 pm Jesse Fowler Said:

    Brett’s passing has left me in shock; I’m deeply saddened to hear this horrible news. Brett was a very good friend during our school years and I’d always hoped we could reconnect. He had a special spark of life that left a mark everywhere he went.

    My deepest condolences – he’s going to be sorely missed.

  15. On July 21, 2023 at 4:45 pm Trent Slobodian Said:

    Brett’s passing was a shock to all of us who worked with him. He was a pleasure to work with for the last 5 years. He always had a smile on his face and was genuinely always happy to have a conversation with anyone around. He will be missed! Our condolences to Brett’s and Katy’s families for their loss.

  16. On July 21, 2023 at 7:27 pm Brett Muir Said:

    I will always have fond memories of doing jiu-jitsu with Brett. No one else could gi choke you in such an inevitable, hilarious and caring way. May the good memories shine through in this difficult time. Look forward to rolling with you when we meet again Brett.

  17. On July 21, 2023 at 7:56 pm Samantha Lawrence Said:

    My family sends our deepest and most sincere condolences to Brett and Katy’s families. Brett was a dependable and positive individual. His upbeat personality and laugh were contagious. I will definitely miss hearing his laugh in the hallways of the office that undoubtedly put a smile on my face each time I heard him and I will miss hearing about his outdoor adventures. A life lived to the fullest stays in fond memories and that’s what Brett did – lived his life to the fullest.

    Sending my sincerest condolences to the Clark family.
    I met Brett 10 years ago after traveling from Ontario to Calgary with a friend for a visit to the rockies. Brett was our informal tour guide who showed us Stephen Ave, 17th, the Bow, and many other gems around the city. He took us to Emerald Lake and even took us both on our very first hike. His kindness and love for the outdoors inspired something in both of us. We fell out of touch but I always wished him well from afar. I am heartbroken to hear of his passing and, like so many others, can’t believe this is true. I look forward to paying my respects this weekend. May you all find some peace through this heartbreaking time.
