The neighbourhood began to be built in the early 1920s with additions in the late 1940s. It was part of Nepean Township until most of the area was annexed by Ottawa in 1950. In its early years, the neighbourhood was a "cottage community". In 1963, the eastern part of the neighbourhood received sewers for the first time, replacing the use of septic tanks. At the same time, parts of the neighbourhood faced expropriation to make room for the proposed "Pinecrest-Deschenes Freeway" which was never built. In 1968, the Britannia Woods housing development was completed in the neighbourhood for placement of families in to rent-to-income units. Britannia Woods is owned by Ottawa Community Housing. It was built by Catkey Construction and financed by the
Ontario Housing Corporation. In 1975, residents approved a grant of over $2 million as part of the Neighbourhood Improvement Program (NIP) to "rehabilitate and preserve" the neighbourhood. The NIP was a federal-provincial-municipal plan to improve and preserve old neighbourhoods and encourage development of the community's environment. The money mostly went toward storm sewer and road construction, and a multi-use recreation facility, plus street lighting, water-front development, playgrounds, tree planting and traffic light installation. The grant would pay for the Belltown Dome hockey arena, a
geodesic dome-shaped building, which officially opened in 1979. In 1979, Nepean City Council approved a $250,000 for improvements in the Nepean section of the neighbourhood, for the creation of a park, an additional sewer and street upgrades. One issue that continued to threaten the community's character was the proposed "Britannia Parkway", which would have run along the Ottawa River connecting the
Kichi Zibi Mikan to the
Queensway. The parkway was never built. Today, the neighbourhood is threatened by being within the Ottawa River's
floodplain. ==Amenities==
