<P> The Upper Canada Central Political Union was organized in 1832 - 3 by Dr Thomas David Morrison (mayor of Toronto in 1836) while William Lyon Mackenzie was in England . This union collected 19,930 signatures on a petition protesting Mackenzie's unjust expulsion from the House of Assembly by the Family Compact . The Reformers won a majority in the elections held in 1834 for the Legislative Assembly of the 12th Parliament of Upper Canada and Mackenzie was again elected as member for York, but the Family Compact held the majority in the Legislative Council, and the two Houses of government were at loggerheads . </P> <P> This union was reorganized as the Canadian Alliance Society in 1835 . It shared a large meeting space in the market buildings with the Mechanics Institute and the Children of Peace . The Canadian Alliance Society adopted much of the platform (such as secret ballot & universal suffrage) of the Owenite National Union of the Working Classes in London, England, that were to be integrated into the Chartist movement in England . In pursuit of this democratic goal, the Chartists eventually staged a similar armed rebellion, the Newport Rising, in Wales in 1839 . </P> <P> The Canadian Alliance Society was reborn as the Constitutional Reform Society in 1836, when it was led by the more moderate reformer, Dr William W. Baldwin . The Reformers experienced a disaster at the 1836 elections for the 13th Parliament of Upper Canada, and the Society took its final form as the Toronto Political Union in 1837 . It was this group of the disenfranchised that began organizing local "Vigilance Committees" to elect delegates to a so - called Constitutional Convention in July 1837 . This became the organizational structure for the Rebellion; most of the rebel organizers were elected Constitutional Convention delegates . </P> <P> The first of those meetings to select delegates to the constitutional convention were held at Doel's Brewery in Toronto on July 28 and 31 . The second meeting was called to order by Samuel Hughes, a member of the Children of Peace, three days later, on August 3 in Newmarket . The meeting appointed Hughes, Samuel Lount, Nelson Gorham, Silas Fletcher, Jeremiah Graham and John McIntosh, M.P.P. as delegates to the convention (and all, with the exception of Hughes and MacIntosh, leaders in the Rebellion). A further eight public meetings across the Home District were scheduled over the next three weeks; each of these public meetings named a local committee of vigilance to organize reform support, prepare a registry of valid electors, and name their delegates to the proposed convention . </P>
