Miller ministry (Ontario)

The Miller ministry was the combined cabinet (formally the Executive Council of Ontario) that governed Ontario from February 8, 1985, to June 26, 1985. It was led by the 19th premier of Ontario, Frank Miller. The ministry was made up of members of the Progressive Conservative Party of Ontario, which commanded a first a majority and then a minority in the Legislative Assembly of Ontario.

The ministry replaced the Davis ministry following the resignation of Premier Bill Davis and the 1985 PC leadership convention. The Miller ministry governed through the last few months of the 32nd Parliament of Ontario and the first few weeks of the 33rd Parliament of Ontario.

After the 1985 Ontario general election, Miller won a plurality of seats but failed to retain the confidence of the Ontario Legislative Assembly. Miller resigned, and was succeeded as Premier of Ontario by David Peterson.
