and Ernie Eves, who never elected to hold the roles during their tenure. Even while another person may hold that ministerial title, the premier is still likely to serve a major intergovernmental affairs role through their presence at first ministers conferences. This role typically has a mostly domestic role, but can also play an international one. Premiers may also choose to hold another ministry title, whether for symbolic reasons or for treating the ministry as a serious priority. While Leslie Frost served for a short time as the minister for the Department of Economics (functionally Minister of Finance), a premier is unlikely to take on a more senior challenging portfolio such as finance, health or education due to their complexity and time demands. Smaller or less complex ministries are more likely to be seen, such as could be seen on the federal level with Canadian Prime Minister Justin Trudeau taking on the federal cabinet position of Minister of Youth. In Ontario, examples of taking more junior files include Kathleen Wynne serving concurrently as Premier and Minister of Agriculture and Food for one year. Dalton McGuinty took on the role of Minister of Research and Innovation for two years, and as Minister of Economic Development for a short time during the great recession of 2008. These instances are still an exception and not the rule. Since Frost's short time in his ministry, no other premier has taken on a ministerial role except for that of intergovernmental affairs. Prior to Frost, relatively few ministers took on cabinet roles, with the informality of the cabinet structure likely permitting more informal involvement in areas of interest. A notable exception seems to be premier George Stewart Henry, who took on the contemporarily important role of Minister of Highways, and also served a short time as Minister of Finance. Cabinet Office The Cabinet Office is the ministry that directly supports the premier, serving the same function provincially as the Privy Council Office does federally. The Cabinet Office plays a coordination role, attempting to harmonize procedures between ministries where possible, as well as monitoring key performance indicators and departmental plans. The Cabinet Office also includes administrative support for a number of committees: Priorities and Planning Committee Cabinet Committee on Emergency Management Treasury Board / Management Board of Cabinet Legislation and Regulations Committee Health, Education and Social Policy Committee Jobs and Economic Policy Committee Premier's Office The Office
