Pierre Trudeau was born in 1919 in Montreal, Quebec. Before entering federal politics, he practiced law and taught constitutional law at the Université de Montréal. He became Prime Minister in 1968, leading the Liberal Party to a majority. His tenure was defined by constitutional reform, bilingualism policies, and responses to Quebec nationalism, including the October Crisis of 1970.

He was elected to Parliament in 2008, became Liberal leader in 2013, and won the prime ministership in 2015.

Key moments include the 1970 invocation of the War Measures Act and the 1982 patriation of the Constitution, which included the Canadian Charter of Rights and Freedoms.
