As well, the Canadian Armed Forces have been called in to deal with labour crises, such as cavalry troops shipped to Edmonton to deal with an expected unemployed riot in 1931 and armoured cars to use strikers at Stratford in 1934. As well, in 1837 prior to Confederation, British troops were used to put down domestic rebellions in Upper and Lower Canada (1837 rebellions), and in the early years of existence as a federation, the Canadian Militia was mobilized for First Nation and Métis insurrections in its "territories", 1869 and 1885 (the first and second Riel Rebellions).
