The 1st Parliament of Ontario was in session from September 3, 1867 until February 25, 1871, just prior to the 1871 general election. This was the first session of the Legislature after Confederation succeeding the Legislative Assembly of the Province of Canada (last session was the 8th Parliament of the Province of Canada). The 1867 general election produced a tie between the Conservative Party led by John Sandfield Macdonald and the Liberal Party led by Archibald McKellar. Macdonald led a coalition government with the support of moderate Liberals.
