Retired Neuroradiologist, St. Michael’s Hospital

It is with profound sadness that the family announces the passing of Walter Montanera on September 23, 2025, at the age of 71. He died peacefully at home, surrounded by his family, after a short but valiant battle with cancer.

Walt was predeceased by his beloved parents, Guerrino and Onelia; and his cherished daughter, Lisa. He leaves behind his three younger siblings, Susan (Egidio), David, and Christina (Mike), who will forever hold him in their hearts.

Mary Lou, his wife and life partner of 45 years; and his three sons, Michael (Katharine), Christopher (Michelina), and Daniel (Jassie) mourn the loss of a loving and devoted husband and father. His grandchildren, Joseph, Matthew, Lisa, and Jason, who were his greatest delight, will forever remember their precious Nonno.

Walt leaves behind an incredible legacy of kindness, generosity, love of family, and professional excellence. He trained as a resident and fellow at St. Michael's Hospital in neuroradiology in the 1980s, with a career in medicine that spanned over 40 years. His professional achievements are best summed up in the 2024 University of Toronto Medical Imaging Department notice of his retirement, following a distinguished career spent at UHN's Toronto Western Hospital and later at St. Michael's Hospital for over 25 years (https://bit.ly/Drwalt).

Those who knew him were forever touched by his wisdom, humility, kindness, and gentle spirit. At this time, the family would like to thank the physicians and colleagues who provided such wonderful and compassionate care — Drs. Julian Spears, Dana Keilty, Warren Mason, and Shayda Ziai. We are grateful to all family, his many friends, and the medical community who showered him with undying support and love.

As per Walt's wishes, cremation has already taken place.

Family and friends are invited to a Funeral Mass to be held at St. Gregory's Catholic Church on Tuesday, September 30th, at 10:30 a.m.

Private family interment to follow.

In lieu of flowers, the family ask that donations be made in Walt's memory to his memorial fund at The St. Michael's Hospital Foundation (www.stmichaelsfoundation.ca/WalterMontanera), Pencer Brain Centre at Princess Margaret Hospital, or Lisa's Legacy: The Lisa Montanera Fund.
