Liberal–Unionists were supporters of the Liberal Party of Canada who, as a result of the Conscription Crisis of 1917 rejected Sir Wilfrid Laurier's leadership and supported the coalition Unionist government of Sir Robert Borden.
After the war, most Liberal–Unionists rejoined the Liberal Party despite efforts by Borden and Arthur Meighen to make the coalition permanent by renaming the Conservative party the National Liberal and Conservative Party. Several Liberal–Unionists ended up staying with the Conservatives including Hugh Guthrie and Robert Manion.
