It is with deep sorrow that we announce the passing of Alexander “John” Lackner, who left us peacefully at Scarborough General Hospital on March 12, 2025, at the age of 85.

John was a devoted father and grandfather. He is survived by his children Laura (Michael), Heather (Roderick), John (Joanna), Lesley (Matthew), and Christine (David). He was the proud grandfather of Joshua, Penelope, Liberty, Emily, Isla, Lily, Molly, and Sabine.

John is also remembered by his siblings Trudy, Ron, Larry, and Gary, as well as his predeceased brother, Conrad. He will be missed by all who knew him.

John’s professional life was marked by his 30 years of dedication as a beloved professor at Durham College. He touched the lives of many students and colleagues alike with his passion for teaching psychology and commitment to fostering knowledge and growth.

Outside of his professional life, John had many interests that brought him joy, including his love of animals, carpentry, fishing, and his cherished Sunday morning newspaper.

A private celebration of life will be held in the summertime, a fitting tribute to his legacy.

In lieu of flowers, donations may be made to the Humane Society of Toronto, an organization John held close to his heart.

John will be remembered for his wisdom and unwavering love for his family. His memory will be cherished forever.
