On September 14,1868, 26 delegates from the BC colonies met at Yale, BC for a convention of the Confederation League. The Confederation League was led by Amor de Cosmos, then a B.C. legislative council member. Mifflin Gibbs, represented Salt Spring Island.
The convention stimulated popular support for the union with Canada as a solution to the Colony of British Columbia’s financial problems. In 1970 BC commissioned a plaque commemorating the convention.
