Swansea was incorporated as a village in 1926. The Swansea Village corporate seal reveals a great deal about the colourful history of this neighbourhood.

Included on the Swansea seal is explorer Etienne Brule, who in 1615 became the first European to set foot on what is now Swansea. Also shown is a First Nations member. This is symbolic in that it recognizes that First Nations members were the first people to inhabit Swansea, hundreds of years ago.

The hills in the Swansea Village seal represent Swansea's rolling countryside, which is similar to the topography found in Swansea, Wales, after which this neighbourhood is named. The water in the Swansea seal refers to Swansea's natural boundaries, which include Lake Ontario, the Humber River and Grenadier Pond.

 In 1967, Swansea Village joined Forest Hill Village as one of the last two independent villages to be annexed by the City of Toronto.

Swansea Village is the only Toronto neighbourhood that has its own community run Town Hall. Swansea is also the only Toronto neighbourhood to have a lake, a river, and a pond as its natural boundaries. Swansea's hilly terrain, winding roads and many mature trees accentuate the storybook houses that line the residential streets of this neighbourhood.
