OPS Structure
The organizational structure of the Ontario Public Service changes from time to time, depending on government priorities and current issues.
Currently, there are over 25 ministries in the OPS, plus Cabinet Office, which supports the work of Cabinet and the Premier. There are three ministries that, like Cabinet Office, have government-wide or enterprise-wide responsibilities. They are the Ministry of Government Services, Ministry of Finance and Ministry of Public Infrastructure and Renewal.
The Ministry of Government Services (MGS) is modernizing government operations and improving public services. It delivers public services for individuals and businesses, as well as providing internal support services to the OPS. Among its many responsibilities, MGS develops OPS human resource policies and strategies, provides leadership and coordination across ministries to ensure an integrated approach to I&IT and provides the public with online access to government services through Service Ontario. The Ministry of Finance is where taxation, fiscal and economic policies of the government are developed. It leads preparation of the annual Ontario Budget. The Ministry of Public Infrastructure and Renewal and coordinates the government’s investments in public infrastructure.
All ministries maintain sites on Ontario.ca that include:
- Profile of the Minister;
- Descriptions of the ministry’s mandate, programs and services;
- Organization chart;
- News releases and backgrounders on issues, policies and new legislation;
- Contacts and links for obtaining further information.
There is also extensive information on government initiatives and priorities on the main Ontario.ca site and on the Premier’s website.
Every ministry sets goals, tracks its performance and reports on results in key areas. The Progress Report on the Ontario.ca site gives an update on results achieved on key government priorities.

There are about 630 agencies, boards and commissions (ABCs) to which the government appoints members.

Many of these organizations are not part of the Ontario Public Service and have their own unique staffing processes and procedures.
