The City of Owen Sound are lowering flags at City Hall and fire stations to half-mast in honour of Paul Materiuk.
Materiuk was a firefighter with the Owen Sound Fire and Emergency Services for five years.
He died unexpectedly while off-duty on Tuesday at the age of 41.
Materiuk is being remembered as an active member of the community supporting veterans, including leadership in the City’s Remembrance Day events, and assisting in the past with the Fire Department’s annual holiday toy drive.
Flags will remain lowered until Monday.
