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 township municipality was formed in 1845. By the mid-19th century, there were a few hamlets including Dalesville, Brownsbury, and Starneville.^[1]

In 1818, Major George Brown, born in England, was granted by the government land on the West River (Rivière de l'Ouest). Together with pioneers Daniel Smith and Captain A. L. Howard, he was able to breathe life into the local industry during the 1820s. George Brown built, among other achievements, a sawmill and gristmill which contributed to the economic growth of the region and led to the formation of Brownsburg village which was named after him. In 1854, the Brownsburg Post Office opened. Later in the third quarter of the 19th century, a major arms factory run by the Dominion Cartridge Company was the major local industry.^[1]

In 1935, the Village Municipality of Brownsburg was officially established by separating from the Township Municipality of Chatham.^[1]

On October 6, 1999, Brownsburg was rejoined with Chatham and the new Municipality of Brownsburg-Chatham was formed. On July 6, 2002, the municipality changed its statutes and became the Town of Brownsburg-Chatham.^[1]

In the 2021 Census of Population conducted by Statistics Canada, Brownsburg-Chatham had a population of 7,247 living in 3,282 of its 3,783 total private dwellings, a change of 1.8% from its 2016 population of 7,122. With a land area of 244.46 km² (94.39 sq mi), it had a population density of 29.6/km² (76.8/sq mi) in 2021.^[5]
