Aged 84, Professor Emeritus, University of Guelph, died suddenly on December 15th in Oakville, Ontario. Chris was predeceased by his wife of 49 years, Virginia (Beatty) Gray, and his parents, Dr. Kenneth Gray and Honor (Tett) Gray. He is survived by his brothers Douglas (Maureen Callahan) and John (Ruth); nieces Julia (Michael Hodge), Caroline (Rob Williams), and Catherine (Nantha Kumar); and nephew Chris Gray.  He is also survived by his sister-in-law, Susan Fowlie (George), niece Meredith (Duncan Callaway) and nephew Jonathan (Jaime).

In his professional life, Chris was an accomplished academic who loved knowledge and learning. In 1990, he was elected a Member of the Royal Society of Canada. A theoretical physicist, he was engaged in research, writing and publishing up to the time of his death.  Those who had the privilege of knowing and working with him mourn his loss as a person, a loving and deeply loved family member, professional colleague, and profoundly loyal friend. There was nothing Chris enjoyed more than engaging in a discussion and exploring ideas ranging from physics problems to the follies and failings of our elected officials - unless it was a spirited game of Liar's Dice with his brothers and extended family members. Chris was genuinely interested in everyone he met and always eager to engage in conversation about the interests and activities of others. A talented athlete in his youth, Chris was deeply interested in sports and followed the fortunes of the Toronto Blue Jays, the Maple Leafs, and the Toronto Raptors.  He was a deeply kind and gentle man, devoted to his dog, Gordy, and Gordy's predecessors Emily, Vivien, Ben, Max, Brinka and Mieka. As one of his dear friends commented, he died too soon – he had more to do and more books to read. He will be sorely missed.

A celebration of life will be held in the spring of 2023, following interment in the Tett family cemetery in Newboro, Ontario. Details will be announced later.
