Harrington Lake (French: La résidence du lac Mousseau) estate is the name of the summer residence and all-season retreat of the Prime Minister of Canada and also the name of the land which surrounds it. It is located near Meech Lake – where the Meech Lake Accord was negotiated in 1987 – approximately 35 kilometres northwest of Ottawa, in an area known as Gatineau Park, amidst the Gatineau Hills in Quebec. The estate is not open to the public, but the Mackenzie King Estate, the retreat of Prime Minister William Lyon Mackenzie King at Kingsmere, is a tourist attraction a few kilometres further south in the park.
