James "Jamie" Weaver Obituary

Published by Legacy Remembers on Jul. 27, 2025.
Jamie Weaver passed away in Toronto on his 44th birthday, surrounded by the immense love of his family and community. Born in Vancouver, he was the beloved son of Gerald Weaver and Carolyn Tate, brother to Nick Weaver, and chosen sibling to dozens of others who counted him as family. He was the devoted husband of Clare Hacksel and a deeply loving father to Lucy and Raines, his proudest accomplishment and the clearest reflection of his spirit.

Growing up, Jamie was both brilliant and kind. From the start, it was clear he had a sharp mind and an even gentler heart. He filled his days with sports like tennis, biking, rollerblading, snowboarding, and hockey, and filled his notebooks with sketches, which later blossomed into a love of both graffiti and fine art. His summers were joyfully spent on biking holidays or at the cottage with cousins, swimming off the beach, laughing under the poplar trees, and soaking up the beauty of Lake Ontario. He had a lifelong passion for music, constantly searching for the next great album to share with friends. Although his taste spanned all genres, he had a special affinity for 90s hip-hop and dubstep.

Jamie was a scientist committed to improving the health of others. At Johnson & Johnson, his work became fundamental to the research and advancement of drug safety. Jamie used his own experiences with cancer and real-world data to inform his own care decisions, which resulted in his being the keynote speaker at the 2021 OHDSI Global Symposium and subsequently being profiled in USA Today. He held degrees from McGill University, the University of Toronto, and New York University. Even in the face of cancer, he continued to pursue a PhD at the University of Oxford, driven by his passion for lifelong learning.

Jamie was a connector, a host, a maker of community. He loved bringing people together, whether through an impromptu dinner party, a long run, or a shared playlist. He was an incredible cook, an energetic athlete, and the kindest person anyone could hope to know. He never judged or spoke ill of others. He offered help freely, supported everyone around him with grace, and always knew how to bring the party to a room.

Besides his many accomplishments, Jamie was most proud of his children. As a father, he was endlessly devoted. He parented with tenderness, duty, and joy. His children embody the very best in him: artistic, inquisitive, kind, and full of love.

Jamie's greatest love was Clare. Theirs was a once-in-a-lifetime bond, steadfast, joyful, and filled with meaning. They built a life full of laughter, curiosity, and unwavering partnership.

A celebration of Jamie's life will be held on August 10, 2025, from 2-5 pm at the East Room, 50 Carroll St, Toronto. All are welcome to be with those who loved him. Jamie adored children and the friends of Lucy and Raines are welcome to attend, childminding will be provided. Jamie loved to dress well, so please wear something bright that would make him smile. Please, no flowers.

I didn't know Jamie all that well, but did have a number of personal and professional conversations with him. He was always attentive, engaged, and exuded warmth. He was gentle but stood up for what he believed in. I can only offer my deepest condolences to his family.

It has been truly an honor and pleasure to know and work with Jamie throughout the years. Among all OHDA colleagues, Jamie was probably the one we have worked together the longest and collaborated the most. I have learned a lot from Jamie via various projects from the stage of designing a study protocol, to analytical details, delivery of the results, and final publication of manuscripts.
The working experience with Jamie was tremendously enjoyable, because he was so smart, kind, energetic, and patient. Outside of work, he was very athletic and a great runner. I still vividly remember the late might when he was running on a treadmill in a hotel's gym after a long day meeting.

Jamie: you have left us such sweet memories and we all LOVE you!

I knew Jamie all of his 43 years, mostly from our wonderful, multi-generational Weaver summers on Lake Ontario. He was everything written about him here. A brilliant and respected scientist, truly devoted to his family and caring for others. Like studying at Oxford despite his cancer, he was an athlete who ran until he could not run any more.

My heart goes out to Clare and the children, to his parents, Gerry and Caroline, his brother Nick and wife Amy and Jamie´s dear Aunt Martha. The Weaver clan won´t forget this very fine man.

To know Jamie was truly a unique experience that consistented of joy, positive energy, fun, crazy adventures, respect, and an immense amount of love. My spirit is heavy knowing that this world no longer has the life force that was the incredible Jamie Weaver. And my heart breaks for his family that he leaves behind, Lucy, Raines, Claire, Nick, his mom and dad. The brightest stars burn brightly and too fast. Rest in peace my friend, gone way too soon.

What a heartbreaking loss. Jamie lived a few doors down from me in Solin Hall at McGill and he was just the warmest soul. We didn´t see much of each other after uni, but it warms my heart to read all the stories here because they´re totally consistent with my memories of the kind, beaming, thoughtful redhead down the hall.

Sending my heartfelt condolences to Jamie´s family, friends and all who loved him. He was taken from us too soon but his light will shine on.

Believe it or not, you actually popped into my head the other day. I was thinking it would be great to catch up - perhaps at a Stern alumni event, since we both have ties to there now, though who ever would have guessed that during our Columbia days. (In fact, way more likely that we would make a joke about that - something about just casually going to business school in our spare time, lol). Thanks for making our pre-grad school co-working time so memorable. Despite it only being a year, I believe, I think of nothing but constant laughs with you - jokes about law school, getting a million masters degrees (which you appear to have tried to make good on; again, lol), having a contest to see who could find the most ridiculous junk emails in our spam filter, and your cluing me in to the latest funny blogs (yes, this was 2007-2008)... all while navigating the underlying seriousness of crunching data to help kids' mental health. Between our shared humor, professional background, interdisciplinary music taste, intellectual curiosity, and appreciation for retro video games, I always saw us as hard-to-categorize kindred spirits. FWIW, my son (coincidentally) shares your name, so consider that strong evidence that your name, and spirit, will be alive and well in our household. Let it be known that your story will be his bedtime story tonight, as a reminder to never be anything but proud of the name he shares with such an impressive dude like you - someone whom everyone liked but also respected. Finally, to your family: My heart and love and condolences. Please know that this random guy who worked next to Jamie for a year at Columbia still remembers Jamie fondly. If you are ever in the NYC area, or NYU Stern (I work there now), please do not hesitate to reach out. I would love to treat you to lunch and reflect upon Jamie's memory, and would be honored to meet all of you. -Mike North

Jamie, you brought laughter, light, and that cheeky grin everywhere you went. You made life more fun just by being in it. You´ll be missed more than words can say, mate. Rest easy.

I remember Jamie vividly and am so sorry to hear about his passing. He was brilliant, kind, conscientious, and completely devoted to his work and to his family. I brought Jamie onto my team at Columbia U and later NYU where he helped all of us do better work on behalf of children with mental health problems and their families. He will be greatly missed.

My heartfelt condolences to Jamie's girls and his loved ones. I had the privilege of working with Jamie at both Columbia and NYU all those years ago- pouring over data and statistics on children's mental health services. I will always remember his keen mind, can-do attitude and the bright smile that can light up a room. -- Serene O.

For years, Jamie and I were the part time North American continent cohort of DPhils. Together, I often joked, we made 1 full time DPhil student.

I´ll never forget our 2021 matriculation/induction weeks. I even got to see him across the Sheldonian as we read an abridged Latin passage and became Oxons. Truly a priceless moment of kinship.

I´ll miss him every time I walk to the top of Headington Hill or hear a dope beat. I´m lucky he had the patience to explain complicated math and programming to me. That he always eviscerated me during Q&A so I could be prepared for reviewer 2 energy.

Because I knew you, I´ve been changed for good.

My condolences and all my best to Jamie´s family. As his PhD supervisor and colleague, I will never forget him. He will always be part of mine and our team´s story, and we will cherish every minute we shared with him. We will continue his extremely important work, and honour his memory while doing so

I did my mph with Jamie 15 years ago and his memory is the most pronounced of anyone from that program years later as he was both the brightest light, the most charming human and an understated cheerleader of others. I didn't know he struggled with cancer. I am so deeply sorry to hear this. I cannot imagine the enormity of the emptiness he's left behind

I remember Jamie when we was a student with the MSBA program at NYU Stern. He was such a wonderful person, and always exuded positivity. I am so sorry for your loss. May Jamie's memory live on in the wonderful family and community he built. -Alanna Valdez

My deepest condolences to Jamie´s family, especially his wife and daughters. I can´t begin to imagine what you´re going through or how difficult this time must be.

Jamie and I were good friends during our Master of Public Health at the University of Toronto. He was an exceptionally bright student who rose to and conquered every challenge put before him. So much so that he enrolled in and completed PhD-level epidemiology statistics courses during his master´s. I wouldn´t be where I am today without him jogging alongside me, encouraging me, and pushing me to take on new challenges during that time.

What made Jamie truly exceptional, though, was his kindness. He was one of the warmest, most welcoming people I´ve ever known. As usually the quietest person in the room, I can attest to the fact that he made everyone feel included and was always genuinely glad to see others.

You will be deeply missed, my friend.

Everything written about Jamie above is so true. His was a one of a kind light. I'm sending my deepest condolences and love to his family and especially to his children. There will never be a shortage of people to remind them of how amazing their father was and how much he means to so many. May he rest easy and may your hearts and spirit be held firm in love during this difficult time and forevermore.

Gerry, Carolyn and Nick our thoughts are with you and your family. We met Jamie & your family during Ian´s and Jamie´s hockey years. As you recall they both played defence. We got to know Jamie when he spent time with us at home and during pre-hockey meet ups. He was a good guy.

Heartbroken to learn of Jamie's passing. What a bright light! I remember how lucky I felt to start my McGill career at Solin Hall with the incredible cast of characters who would remain connected through our college lives and beyond. Sending love to the family... he was one of a kind.
