This was the largest cabinet in Ontario's history; Miller also carried an unprecedented seven ministers without portfolios.

Also among the experienced cabinet members were Premier Miller himself, Bette Stephenson (appointed Chair of Management Board of Cabinet), and Bob Welch (appointed Deputy Premier and Attorney General).

Among the ten newly appointed cabinet ministers were future Premiers Mike Harris (appointed Minister of Natural Resources} and Ernie Eves (appointed Provincial Secretary for Resource Development and, on March 22, 1985, to the newly created portfolio of Ministry of Skills Development).

Miller signaled a recognition of this shifting political base in the way he filled the vacancies.

He did not add a single new Toronto MPP to his cabinet, but selected three MPPs from the previously neglected Peel, York, and Durham regions that surround Metro Toronto: before the election they only had Ashe and Gregory, but after they added to those two Cousens, Cureatz, and Stevenson.
