The Legislative Assembly of Ontario has 124 members of provincial Parliament (MPPs) who each represent a constituency. A constituency (also called a “riding” or “electoral district”) is a geographical area. Ontario’s constituencies are outlined in the Representation Act, 2015 (external link). Residents of these areas are referred to as “constituents.” Constituents vote to elect their MPP to represent them in the Legislature.

What does my MPP’s constituency office do?
Constituency offices are non-political and help MPPs serve their constituents. MPPs spend time in these offices to meet with constituents and hear their concerns. Constituency office staff represent MPPs when MPPs can’t be there. The offices are staffed even if the constituency becomes vacant, such as during the election period or if an MPP resigns.
MPPs have at least one office in their ridings. If the constituency is large geographically, the MPP may have more than one office to be more accessible.
What else does my MPP do in my constituency?
MPPs attend events to learn about the needs of their constituents. These events can include fundraisers, grand openings, and ceremonies. MPPs may also show other members and politicians around the area.
