Leaders of the Official Opposition
In the First Parliament, following the general election of 1867, the Members who sat in the House opposite the government of Sir John A. Macdonald did not constitute a party but a coalition of various interests, just as the government did. A number of historians state that John Sandfield Macdonald (Reform Member for Cornwall and the first Premier of Ontario), who had campaigned in alliance with Sir John A. Macdonald in the general election, was appointed Leader of the Opposition by the government. Other historians hold that although Alexander Mackenzie (Lambton) was not formally appointed Leader of the Opposition until March 6, 1873, when he assumed the leadership of the Liberal Party, he was de facto Leader of the Opposition as early as 1869.
