A number of regionally and nationally well-known[citation needed] musicians, filmmakers, and artists live in Chelsea, including Ian Tamblyn.

The southern border is 5 kilometres (3.1 mi) south of Old Chelsea, the municipality historical centre, and runs north to the community of Farm Point.

North of Old Chelsea is Camp Fortune, a popular alpine ski club 15 minutes from Downtown Ottawa.

[citation needed] 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.

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.

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.
