In Parliament, Sevigny became a supporter of Canadian participation in World War I despite the strong opposition of most Quebecers, and became a staunch Conservative. He was appointed Deputy Speaker in 1915, and in 1916, he became Speaker of the House of Commons of Canada.
Prime MinisterRobert Borden was facing an increasing divisive crisis over conscription with the country divided between English Canadians who supported the measure and French-Canadians who fervently opposed it. In early 1917, Borden asked Sevigny to leave the Speaker's chair and join the Cabinet to help the government persuade Quebecers of the government's case.
Sévigny was appointed Minister of Inland Revenue, and was required by the laws of the time to resign his seat and run in a by-election. He was re-elected by a margin of only 257 votes.
In June, Borden introduced conscription and, of the French Canadian Members of Parliament, only three voted for the conscription bill, including Sévigny.
Borden formed a Union government with dissident Liberals and called a general election in 1917 on the conscription issue. The country divided largely along linguistic lines: the Conservative candidates were wiped out in Quebec in a rout that cost Sévigny his seat. Borden's coalition dominated the election in English Canada, however, and he was returned with a strong majority.
Judicial career
In 1921, the Conservative government appointed Sévigny to the Quebec Superior Court on which he served for 39 years, becoming Associate Chief Justice in 1933 and Chief Justice in 1942.

The position of Secretary of State for Canada was not legally eliminated until 1996 when its remaining responsibilities were assigned to other cabinet positions and departments, particularly the newly created position of Minister of Canadian Heritage.
