Colin Leslie Casey

Colin Leslie Casey, beloved husband, father, grandfather and friend passed away peacefully on Tuesday, November 4, 2025. Never wanting to be the centre of attention, he slipped away in a moment of quiet after all the goodbyes had been said.

Colin was born in Ottawa, Ontario on November 14, 1948, the son of Eileen and Leslie Casey.  He enjoyed recounting colourful memories of growing up in Ottawa with his mother, grandparents, and a host of aunts, uncles and cousins.  As a young man, Colin lived for many years in Kingston, ON.  A proud graduate of Queen’s University in Kingston, his career as a Certified Drug and Alcohol Counsellor took him to jobs in Kanata, and Yellowknife, NT where he earned the affection of the Indigenous peoples through his respect for, and participation in their cultural traditions and way of life.

Upon his return to Ontario, Colin settled in Barrie, ON, where he spent many years working at the Southdown Institute in Aurora, Ontario.  Upon his retirement in 2009, Colin volunteered for Hospice Simcoe in Barrie.  He valued the opportunity to greet families and to simply be there to listen when they needed a quiet presence.

Colin will be remembered for his kindness, his gentle spirit and his love of family.  His unfailing optimism, sense of humour, and his joy in randomly belting out songs from the 60’s and 70’s gave him the strength and determination to overcome numerous health challenges, including Parkinson’s Disease which he battled with reluctant acceptance and a steady grace.

Colin is survived by his wife, Leslie and his children: Kellie (Doug), Brent (Natasha), Vicki (Shawn), Kirsten (Ryan) and Kerri (Chris), as well as Graeme, Laura and Lesley (Asher) through his marriage to Leslie.  He is also survived by Jadyn, Hailey, Clare, Lauren, Jack, Megan, Elise, Hannah, Della, Oliver and Marlow, his beloved grandchildren.  Colin lived for his family.  He lit up with every visit, every text, picture and video sent by his children and grandchildren when he became unable to travel.

Burial and a Celebration of Colin’s Life will take place in the Spring.

In lieu of flowers, the family would welcome contributions to Parkinson Canada  or Hospice Simcoe.

Leslie, and all of Colin’s family would like to thank the amazing team of doctors and therapists, including Dr. Saman Zamanian, Dr. Remo Zadra, Dr. Michael Aubrey and Colin’s physiotherapist, Sara Meischke, who supported Colin through his years of medical challenges with compassion and the highest standard of care. Deepest thanks also to the staff of Roberta Place Long Term Care in Barrie for their kindness and compassion in caring for Colin during the final month of his life.
