LILLIAN R. MOSTOW (NEE HALPARIN) AUGUST 31, 1926 – JANUARY 18, 2026
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.

JEAN SHIRLEY KOPSTEIN FEBRUARY 14, 1934 – JANUARY 11, 2026
Jean Shirley Kopstein passed away peacefully, a month shy of her 92nd birthday, with her three devoted children by her side.
Known to her family as Shaney, Jean will be deeply missed by her children, Ivy (Murray), Ruth, and Alan; her grandchildren, Louis, Minnie (Patrick), Leo (Ashley), and Max (Brynne); her great-grandchild, Margot; her brothers, Martin (Grace) and Gary; as well as her nieces, nephews, cousins, and friends.
Jean was born on Valentine’s Day in 1934 in Montreal. In 1939, her family returned to Winnipeg, where they settled in the city’s North End. During her second year at the University of Manitoba, Jean met Bobby Kopstein, the light of her life. They married on June 23, 1954. That same year, Jean graduated as a teacher and taught for three years before choosing to stay home to raise their family.
Later in life, Jean embarked on a meaningful professional career and left her mark on every organization she served. She worked as a counsellor at the Addictions Foundation of Manitoba, became a specialist in adult education and went on to become Director of Staff Development and Training for the provincial Department of Corrections. During that time, she was also seconded by the government to establish the Manitoba Women’s Directorate. She was often described as an inspiration – a wonderful colleague, a thoughtful leader, and a great friend.
Jean had many passions and immersed herself fully in all of them. She loved travelling with Bob and had a deep appreciation for film, music, art, design, fashion, and food from many cultures – always in search of the perfect muffin! She formed deep bonds with family and friends, with constant concern for the well-being of those she loved. Jean and Bob were humanists who led by example, instilling strong values in their family. Jean had a unique and engaging presence. She was outgoing, vivacious, curious, and intelligent. She lit up a room with her energy and her beautiful, warm smile.
Diagnosed with glaucoma in her 60s, Jean began a long and challenging period in her life. After the loss of Bob in 2014, she faced further health difficulties. Despite these challenges, her desire to live fully never waned. She remained interested in the world around her and took great joy in family dinners, trips to Winnipeg Beach, and spending time with family and friends. The family extends heartfelt thanks to everyone involved in Jean’s care over the many years, especially those who went above and beyond. They are deeply grateful to Shaftesbury Park for its support, and in particular to Jean’s caregivers for their outstanding care, compassion, and kindness. The family would also like to express appreciation to the clergy and staff of the Shaarey Zedek Synagogue for their kindness and support. Donations in Jean’s memory may be made to the Jewish Foundation of Manitoba or to a charity of your choice.
