Lower Canada experienced during and after the rebellions great hardships and oppression and exploitation that would last until the Quiet Revolution, including a systematic program of assimilation; the mandatory use of English in all public matters and business; as well as an economic recession. The Rebellions lead to many more conflicts most notably the 1845 Rebellion Losses Bill which caused enraged Orangist and Tory Anglophones to Burn the Building of Parliament in Montreal, which lead to the construction of Ottawa. A large number of people were drawn to the promise of a better life in the United States to form the large majority of the French American community, concentrated mostly in the industrial north.
