John Gilbert Seguin passed away surrounded by his family on February 10, 2026 at Toronto General Hospital. Born in Kemptville, Ontario, he was the eldest son of John and Mary (née Prodonick) Seguin, both predeceased.

A beloved husband, Gilbert is survived by his wife, Anne Seguin (née Ferguson), whom he married in 1978. Together, they relocated to Oxford County shortly after they married.

He was a devoted father to Michelle Seguin and Jeffery Seguin (Gisell), and a proud grandfather to Douglas and Elliot, who brought him immense joy. He was predeceased by his son, Douglas, in 1985.

Gilbert committed his life to farming, a calling that reflected his traditional roots, his respect for the land and his steadfast work ethic. Gilbert was a devoted family man who cherished time spent with loved ones. He enjoyed nature, science, history and sports (especially broomball) and valued the friendships and connections he made throughout his life.

He is also lovingly remembered by his siblings: Elaine Lang (late Bob), Jeannie Young (Roy), Patsy Henry (Eric), Michael Seguin, Debbie Seguin-Redick (Mike), and Roger Seguin (Connie). Predeceased by his brother George Seguin (Diane), He will be missed by his brothers- and sisters-in-law, including John Ferguson, Glen Ferguson (Jennifer), Gary Ferguson (Maria), and Gail Gilmer (Gary), as well as many nieces, nephews, extended family members, and friends.
