The new constitution vested in the Queen responsibility for peace, order, and good government, as D'Arcy McGee had desired. In practice, though, the Second Reform Act, 1867, and the emergence of a two-party system decreased Victoria's personal room for manoeuvre. Still, the ceremonial role for the monarchy remained unaltered and the first visit of a member of the Royal Family to the Dominion of Canada took place two years after its creation; the sovereign's second son, Prince Arthur, arrived for training with the Rifle Brigade based at Montreal; of the Prince, the Lady Lisgar, wife of Governor General the Lord Lisgar, noted in a letter to Victoria that Canadians seemed hopeful Prince Arthur would one day return as governor general himself. In the same year, Rupert's Land was ceded to the Crown in Right of Canada from the Hudson's Bay Company, pulling it into the jurisdiction of the Northwest Territories. This move sparked a Métis rebellion and the establishment by Louis Riel of a provisional republican government in the Red River Valley. Following negotiations with Riel's government, the province of Manitoba was established in 1870 by the granting of Royal Assent to the Manitoba Act by Governor General the Earl of Dufferin.
