Note : The titles “Conservative” and “Liberal-Conservative” were sometimes interchanged between 1867 and 1942. Often simply referred to as Conservative or Tory.
The Liberal-Conservative Party was the formal name of the Conservative Party of Canada until 1873, and again from 1922 to 1938, although some Conservative candidates continued to run under the label as late as the 1911 election and others ran as simple Conservatives prior to 1873. In many of Canada's early elections, there were both "Liberal-Conservative" and "Conservative" candidates; however, these were simply different labels used by candidates of the same party. Both were part of Sir John A. Macdonald's government and official Conservative and Liberal-Conservative candidates would not, generally, run against each other. It was also common for a candidate to run on one label in one election and the other in a subsequent elections.
Party label changes to "Progressive Conservative Party" in December 1942.
The merger of the Progressive Conservative Party and the Canadian Alliance in 2003 results in a new Conservative Party of Canada.
