The union of 1841 did its work, and the political conditions of Canada again demanded another radical change commensurate with the material and political development of the country, and capable of removing the difficulties that had arisen in the operation of the act of 1840. The claims of Upper Canada to larger representation, equal to its increased population since 1840, owing to the great immigration which had naturally sought a rich and fertile province, were steadily resisted by the French Canadians as an unwarrantable interference with the {371} security guaranteed to them under the act. This resistance gave rise to great irritation in Upper Canada, where a powerful party made representation by population their platform, and government at last became practically impossible on account of the {372} close political divisions for years in the assembly. At the head of the party demanding increased representation was Mr. George Brown, an able man of Scotch birth, who became the conductor of a most influential organ of public opinion, _The Toronto Globe_, and the leader of the "Grits," or extreme wing of the Reformers or Liberals. In opposition to him were allied Mr. George Etienne Cartier, once a follower of Papineau, but now a loyal leader of his race, and Mr. John Alexander Macdonald, who had occupied a prominent position for years as a Conservative leader. The time had come for the accomplishment of a great change foreshadowed by Lord Durham, Chief-Justice Sewell, Mr. Howe, Sir Alexander Gait, and other public men of Canada: the union of the provinces of British North America. The leaders of the different governments in Canada, and the maritime provinces of Nova Scotia, New Brunswick, and Prince Edward Island combined with the leaders of the opposition with the object of carrying out this great measure. A convention of thirty-three representative men[1] was held in the autumn of 1864 in {373} the historic city of Quebec, and after a deliberation of several weeks the result was the unanimous adoption of a set of seventy-two resolutions embodying the terms and conditions on which the provinces through their delegates agreed to a federal union. These resolutions had to be laid before the various legislatures and adopted in the shape of addresses to the Queen, whose sanction was necessary to embody the wishes of the provinces in an imperial statute.
