four Presbyterian denominations, only two others gained a foothold in the province. The small "Stamford Presbytery" of the American Secessionist tradition was formed in 1835 in the Niagara region, and the Scottish Reformed Presbyterian or "Covenanter" tradition was represented in the province to an even lesser extent. Despite the numerous denominations, by the late 1830s, the Church of Scotland was the main expression of Presbyterianism in Upper Canada. Mennonites, Tunkers, Quakers, and Children of Peace These groups of later Loyalists were proportionately larger in the early decades of the province's settlement. The Mennonites, Tunkers, Quakers and Children of Peace are the traditional Peace churches. The Mennonites and Tunkers were generally German-speaking and immigrated as Later Loyalists from Pennsylvania. Many of their descendants continue to speak a form of German called Pennsylvania Dutch. The Quakers (Society of Friends) immigrated from New York, the New England States and Pennsylvania. The Children of Peace were founded during the War of 1812 after a schism in the Society of Friends in York County. A further schism occurred in 1828, leaving two branches, "Orthodox" Quakers and "Hicksite" Quakers. Poverty In the decade ending in 1837, the population of Upper Canada doubled, to 397,489, fed in large part by erratic spurts of displaced paupers, the "surplus population" of the British Isles. Historian Rainer Baehre estimated that between 1831 and 1835 a bare minimum of one-fifth of all emigrants to the province arrived totally destitute, forwarded by their parishes in the United Kingdom. The pauper immigrants arriving in Toronto were the excess agricultural workers and artisans whose growing ranks sent the cost of parish-based poor relief in England spiralling; a financial crisis that generated frenetic public debate and the overhaul of the Poor Laws in 1834. "Assisted emigration," a second solution to the problem touted by the Parliamentary Under-Secretary in the Colonial Office, Robert Wilmot Horton, would remove them permanently from the parish poor rolls. The roots of Wilmot-Horton's "assisted emigration" policies began in April 1820, in the middle of an insurrection in Glasgow, where a young, already twice bankrupted William Lyon Mackenzie was setting sail for Canada on a ship called Psyche. After the week-long violence, the rebellion was easily crushed; the participants were driven less by treason than distress. In a city of 147,000 people without a regular parish system of poor relief, between ten and fifteen thousand were destitute. The Prime Minister agreed to
