Niagara area for the Methodist Episcopal Church – an American branch of Methodism. As British immigration increased, Methodism in Upper Canada was torn between those with ties to the Methodist Episcopal Church and the British Wesleyan Methodists. Ryerson used the Christian Guardian to argue for the rights of Methodists in the province and, later, to help convince rank-and-file Methodists that a merger with British Wesleyans (effected in 1833) was in their best interest. Presbyterians The earliest Presbyterian ministers in Upper Canada came from various denominations based in Scotland, Ireland, and the United States. The "Presbytery of the Canadas" was formed in 1818 primarily by Scottish Associate Presbyterian missionaries, yet independently of their mother denomination in the hope of including Presbyterian ministers of all stripes in Upper and Lower Canada. Although successfully including members from Irish Associate, and American Presbyterian and Reformed denominations, the growing group of missionaries belonging to the Church of Scotland remained separate. Instead, in 1831, they formed their own "Synod of the Presbyterian Church of Canada in Connection with the Established Church of Scotland". That same year the "Presbytery of the Canadas", having grown and been re-organized, became the "United Synod of Upper Canada". In its continued pursuit for Presbyterian unity (and a share of government funding from the clergy reserves for established churches) the United Synod sought a union with the Church of Scotland synod which it finally joined in 1840. However, some ministers had left the United Synod prior to this merger (including, notably, Rev. James Harris, Rev. William Jenkins, and Rev. Daniel Eastman). In the 1832 new Secessionist missionaries began to arrive, belonging to "The United Associate Synod in Scotland" (after 1847, the United Presbyterian Church of Scotland). Committed to the voluntarist principle of rejecting government funding they decided against joining the "United Synod of Upper Canada" and on Christmas Day 1834 formed the "Missionary Presbytery of the Canadas". Although this new presbytery was formed at Rev. James Harris's church in Toronto, he and his congregation remained independent from it. However, the voluntarist, Rev. Jenkins and his congregation in Richmond Hill joined the Missionary Presbytery a few years later. Rev. Eastman had left the United Synod in 1833 to form the "Niagara Presbytery" of the Presbyterian Church in the USA. After this presbytery dissolved following the Rebellion of 1837, he rejoined the United Synod which then joined the Church of Scotland. Outside of these
