Our beloved matriarch, Lillian Mostow, passed away peacefully at 99 years of age at the Simkin Centre, where she had received exemplary care for more than six years.
Lillian was quite the character. She said what she meant, without filters; she was strong, opinionated, and fiercely protective of those she loved. You always knew exactly where you stood with her.
The youngest of five, Lillian grew up on Dufferin Ave. in north-end Winnipeg, next door to her father’s sweater factory, Standard Knitting. Clever and artistic, she studied interior design at the University of Manitoba before marrying Harold Mostow in 1947. They had a wonderful life together. They loved to throw parties for their family and friends at their home on Brock St. and Lillian’s Sunday pancake brunch was a cherished tradition. To escape Winnipeg’s brutal winters, they vacationed first in Mexico and later in Maui, where they celebrated their 50th wedding anniversary as a joint simcha with the marriage of her daughter, Morri Mostow, to Douglas Long. After their children left home, Lillian accompanied Harold on his business trips to Asia, where she bought beads and semi-precious stones for the necklaces she designed for her home-based business, My Place. In 2005, two years after being widowed, she moved with her daughter and son-in-law to Gabriola Island, BC, where they happily shared a home for 14 years. Despite being a city girl all her life, she adapted seamlessly to country living. She soon had bridge partners and friends and began volunteering. Fiercely independent, she drove around the island in her red PT Cruiser, going to the library, attending events and taking the ferry to Nanaimo’s aquatic centre to swim a few times a week.
In 2019, failing mobility and cognition necessitated a move back to Winnipeg, to the Simkin Centre, where she spent her final years. At 99, she was still going to concerts, synagogue services and exercise classes.
Lillian was predeceased by her parents, Moses/Moishe and Clara/Chaika Halparin, her siblings, William/Bill Halparin, Norman Halparin, Archie Halparin and Freda Fox, and by Harold Mostow, her husband of 56 years. She is mourned by her children, Morri Mostow (Douglas Long), Michael Mostow and Sydney Mostow; by her grandchildren, Cassandre Aras, Clotilde Aras (Nicolas Gautier), Kyle Mostow (Rachel Minuk) and Mauro Mostow Palmer; by her great-grandchildren, Emily Mostow, Léonard, Céleste and Lilas Gauthier; by her many nieces, nephews and cousins; and by all those whose lives she touched.
Grateful thanks to the extraordinary staff at the Simkin Centre who took such good care of Lillian. Also to Rabbi Carnie Rose, who officiated her funeral with great warmth and compassion at the Shaarey Zedek Synagogue on January 22, 2026.
