The Joint Committee officially convened in April 1904, in Toronto, bringing together appointed representatives from the Congregationalist, Methodist and Presbyterian Churches, to negotiate church union. Meetings continued through to 1908, when the terms written in the Basis of Union were agreed upon and sent to the negotiating churches, for discussion and approval. By 1912, both the Congregationalists and the Methodists had agreed to the terms. The decision was more contentious for the Presbyterian Church, though in 1916, their General Assembly decided to go ahead with the union.
Between 1916 and 1925, the Joint Committee worked to complete the union and defeat those opposing it, including the newly formed Presbyterian Church Association.
