Leslie John Kloc

June 10, 1935 - December 11, 2025

It is with great sorrow and sadness that we announce the passing of Leslie on Thursday, December 11, 2025, at Gilmore Lodge, at the age of 90. Leslie was the devoted husband of Betty for 63 years and the beloved father of Cathy (Harvey Gracey), Kim, and Trish. He will be deeply missed by many nieces, nephews, family, and friends. Leslie dedicated his career to working as a chemical engineer and was exceptionally skilled, whether it involved fixing light switches or building the family home. Above all, he was deeply committed to his family, attending every ballet performance, and was known for his quiet generosity, giving selflessly without any expectation in return.

A heartfelt thank you goes out to Hotel Dieu Shaver Hospital, the Rainbow Unit at Niagara General Hospital, and Gilmore Lodge - Bay Beach for all of their care and compassion for Leslie over the years.

Visitation will take place on Thursday, December 18, 2025, from 2 PM to 4PM and 6 PM to 8 PM at Patterson Funeral Home (6062 Main St., Niagara Falls, Ontario). A Chapel Service will be held on Friday December 19, 2025 in the funeral home chapel at 11 AM. A graveside service to follow at Fairview Cemetery (4501 Stanley Ave., Niagara Falls, Ontario). Donations in memory of Leslie can be made to the Alzheimer's Society. Online condolences may be offered at www.pattersonfuneralhome.com.
