Nathan Yacowar

Peacefully, at home, surrounded by his family on Sunday, April 12, 2026, at the age of 96. Beloved and cherished husband of Lucy Wiseman for 72 years. Loving and incredible father and father-in-law of Ronnie and Patricia Yacowar, Cynthia Yacowar, Mayer Yacowar and Andrea Beltrano, and Eta Yacowar and Laurent Levi. Proud Zaidie of Aaron Sweeney and Michaela Shulman, Rachel Sweeney and Michel G, Avra Sweeney and Tyler Safran; Noah, Talia, and Eliana Yacowar; Devon and James Levi. Dear brother and brother-in-law of the late Evelyn and the late Sam Maslowsky; and beloved brother-in-law of the late Jeannie and the late Maxie Kirsh. Cherished uncle of Donna and Sheldon Cohen, Stanley and Jennifer Kirsh, Debbie and Arthur Cohen, Kenny Maslowsky, Chris and the late Jerry Maslowsky, and the late Bobbi Maslowsky.

Nathan will be lovingly remembered and deeply missed by his family and by all who knew and loved him. Special thanks to his devoted caregivers Lina Douskos, Shirley Debance, Jean Synette, and Reynaldo Valdez; and to the CLSC staff—Louise Lachapelle, Ryan Jones, Penny Bekiarakis, Alexandre Venne, and Pascale Belley—as well as all the wonderful nurses and orderlies for their compassionate care and support.

Nathan was a deeply loving husband, father, and grandfather who showed his love and dedication through constant affection, guidance, and support. Born in Medicine Hat, Alberta, he studied Engineering Physics and Atmospheric Physics at the University of Saskatchewan, the University of Toronto, and McGill University. He built a distinguished career at the Canadian Meteorological Centre in Dorval, and later served as Chief of Research and Development in Statistics and Probability at Environment Canada, contributing to early work in weather prediction, radar, and computer modelling. Known for his sharp mind and steady judgment, he approached both his work and his family with integrity, thoughtfulness, and love.

Nathan was also a founding member of the Young Israel of Chomedey on Elizabeth Street in the early 1960s, where he served as President, Chairman of the Religious Committee, and Chairman of the Adult Education Committee. He organized the High Holiday aliyot and was the bazaar chairman for four decades, dedicating countless hours of service. Deeply committed to his community, he was part of a three-person committee that secured provincial funding for Jewish day schools in the 1960s, benefiting generations of families in Montreal.

At age 46, at the height of his career and family life, Nathan became paralyzed. What followed were more than 50 years of physical limitation and radiating pain. And yet, he persevered—he just kept going and going, never ever complaining, defying the odds year after year, with a strength that never let go.

He gave generously of his time and attention, always ready to help, advise, and encourage others, and he will be remembered for his strength, intelligence, and enduring kindness. He was one of a kind and will be deeply missed by his family and by all who had the privilege of knowing him.
