# Robarts ministry

The Robarts Ministry was the combined cabinet (formally the Executive Council of Ontario) that governed Ontario from November 8, 1961, to March 1, 1971. It was led by the 17th Premier of Ontario, John Robarts. The ministry was made up of members of the Progressive Conservative Party of Ontario, which commanded a majority of the seats in the Legislative Assembly of Ontario throughout its duration.
The ministry replaced the Frost ministry following the resignation of Premier Leslie Frost and the 1961 PC leadership convention. The Robarts ministry governed through the second half of the 26th Parliament of Ontario, the entirety of the 27th Parliament of Ontario, and most of the 28th Parliament of Ontario.
Robarts resigned in 1971 and was succeeded as Premier of Ontario by Bill Davis.
