Northumberland is mourning the loss of a long-time leader following the passing of Leo “Dalton” McDonald.
On Wednesday, Dec. 17, Northumberland County council observed a moment of silence in recognition of the former Township of Alnwick/Haldimand reeve and mayor and county councillor, who was best known as Dalton.
“Mr. McDonald dedicated more than 20 years to public service, serving on the Township of Alnwick/Haldimand’s council and as a county councillor from 2010 to 2014,” recalled county staff. “He remained deeply connected to and actively involved in his community throughout his life.”
Council and staff also extended condolences to his loved ones – and “all those who had the privilege of knowing him.”
Flags at county headquarters were also lowered to half-mast in a tribute to his service and community spirit, added officials.
The Township of Alnwick/Haldimand also lowered its flags to half-mast in recognition of his significant contributions to municipal governance and public service on Tuesday, Dec. 16.
“Mr. McDonald began his service on township council in 1992, served as councillor, was deputy reeve from 1998 to 2000, (then) was acclaimed as deputy reeve in 2006 and later served as mayor from 2010 to 2014,” recalled township staff, while the community also extended condolences.
According to his obituary, McDonald passed away peacefully at Ed’s House with family by his side on Dec. 11, 2025.
McDonald was described as a successful tobacco farmer, business owner of Dalton McDonald Motors, and served in the political arena for more than two decades.
His obituary states that a celebration of life will take place in spring 2026 at Coldspring’s Memorial Hall.
“Rest in peace former Alnwick/Haldimand Mayor McDonald,” wrote Brighton Mayor Brian Ostrander online, following the news of his passing. “Brighton honours your life and service.”
