The Ontario Police Memorial Foundation honours and remembers police officers in Ontario who have lost their lives in the line of duty. Its main purpose is to build, maintain, and manage a permanent memorial recognizing these fallen officers, as well as to support their families and loved ones through acts of remembrance. The Foundation also organizes annual ceremonies to pay tribute, emphasizing that these officers are "Heroes in Life, Not Death".

The Foundation’s geographic focus is the province of Ontario. Its activities and events, including the annual Ceremony of Remembrance, are centred at Queen’s Park in Toronto. While the primary focus is provincial, these ceremonies draw participants from across Ontario and have attracted police officers and supporters from the rest of Canada, the United States, and Europe.

Key program highlights include the stewardship of the Ontario Police Memorial, which features bronze statues and granite walls engraved with the names of fallen officers. The Foundation also hosts the annual Ceremony of Remembrance every first Sunday in May, which sees thousands gather to honour the memory and service of deceased officers. In addition, the Foundation provides support to the families of those officers and raises funds for the maintenance of the memorial and related initiatives throughout the year.
