History
Chelsea is named after the Vermont town of its first settler, Thomas Brigham, who was a partner and son-in-law of Philemon Wright and arrived there in 1819. The name has been in use since the early 19th century: Old Chelsea (1819), Parish Saint-Stephen-of-Chelsea (1835), Chelsea (circa 1870). In 1875, the municipality was established as Hull-Partie-Ouest, or commonly referred to as West Hull. The municipality was renamed to its current name in 1990.

During World War II, the Royal Canadian Navy wanted to understand more about the propagation of radio waves and how they were affected by the earth's ionosphere so that German radio transmissions could be intercepted more efficiently. In cooperation with the National Research Council, the RCN established a "field intensity station" at Chelsea in 1941 to monitor the height of the ionosphere.

Chelsea, also known as an ionospheric observatory, was established in 1941 and closed down in 1947. It was located on the north side of Old Chelsea Road a few hundred yards west of Highway 105. The Chelsea station operated during the post-war period but in 1947, its work was transferred to the Defence Research Board's new Radio Propagation Laboratory in Ottawa. Shortly thereafter, the station was demolished. Today, there are no traces of the single shack or the many masts that were once erected on the property.
