Sir Louis-Hippolyte Lafontaine was the first Canadian to become Prime Minister of the United Province of Canada and the first head of a responsible government in Canada. He was born in Boucherville, Lower Canada in 1807. A jurist and statesman, Lafontaine was first elected to the Legislative Assembly of Lower Canada in 1830. He was a supporter of Papineau and member of the Parti canadien (later the Parti patriote). After the severe consequences of the Rebellions of 1837 against the British authorities, he advocated political reforms within the new Union regime of 1841.
