According to their oral tradition, the Katzie people are the descendants of the Oe'lecten and Swaneset communities, two of five established by the Creator in present-day Greater Vancouver.

[2] The Creator assigned a chief to lead each community: Oe'lecten (θéləctən) at Pitt Lake, Swaneset at Sheridan Hill (in Pitt Meadows), Xwoe'pecten at Port Hammond (in Maple Ridge), C'simlenexw at Point Grey (in Vancouver), and Smakwec at Point Roberts (in Washington, US).

[4] It is said that Swaneset, at the behest of the Creator, shaped the land of his area so that it would be abundant in berry and root crops and thus suitable for human life.

As the new Golden Ears Bridge was in Katzie territory, the nation signed a Benefit Agreement with TransLink in September 2004 to establish the responsibilities of both parties.

[12] həṅq̓əmín̓əḿ, the downriver dialect of Halkomelem, is still spoken by Katzie peoples despite colonization attempts (including the Canadian Residential School System).
