John A. Mathieson Conservative John A. Mathieson Conservative The 1912 Prince Edward Island general election was held in the Canadian province of Prince Edward Island on January 3, 1912.

Mathieson was designated Premier in December 1911 at the behest of the Lieutenant Governor, following the defeat of his predecessor, Liberal Premier H. James Palmer in a by-election, one that ultimately shifted the balance of power in the Legislature from a bare Liberal majority to a situation in the Conservative's favour.

The Legislature of Prince Edward Island had two levels of membership from 1893 to 1996 - Assemblymen and Councillors.

This was a holdover from when the Island had a bicameral legislature, the General Assembly and the Legislative Council.

In 1893, the Legislative Council was abolished and had its membership merged with the Assembly, though the two titles remained separate and were elected by different electoral franchises.
