The Young People's Union (Y.P.U.) of the United Church and its Conference-level units were organized around 1935, following the recommendation of the Interprovincial Young People's Council (1934). Saskatchewan Conference's Y.P.U. appears to have been formed sometime after the first National Y.P.U. Council, in mid-1935.

In 1965, the United Church Y.P.U. and its constituent Conference- and Presbytery-level groups appear to have been reorganized to form units of Kairos.
