Brownsburg-Chatham, Quebec Brownsburg-Chatham, Quebec Brownsburg-Chatham is a municipality in the Laurentides region of Quebec, Canada, part of the Argenteuil Regional County Municipality. It is located along the Ottawa River, just west of Lachute, and includes the communities of Brownsburg, Cushing, Dalesville, Greece's Point, Pine Hill, and Saint-Philippe. Economic activities include agriculture, tourism and the manufacture of explosives. It is the hometown of Gilles Lupien, retired defenceman of the Montreal Canadiens. Chatham Township was established in 1799, and named after English Statesman William Pitt, 1st Earl of Chatham (1708–1778). Mostly populated by rich American Loyalists, its post office opened in 1829 and the
John Pitt, 2nd Earl of Chatham recalled in disgrace. His appearance before a parliamentary enquiry did him no favours, particularly when it emerged that he had presented the King with a private memorandum which ought to have gone to the Secretary of State for War first. Spencer Perceval's government withdrew its support from Chatham and he was forced to resign from the Ordnance in May 1810. Chatham's political and military reputation was ruined. A poem circulated making fun of his inactivity and the lack of co-operation between the army and navy: Chatham did not serve actively again, but was promoted to full General in January 1812.
