Mississauga Official Plan 2051 guides how the City will grow and develop, as required by the Ontario Planning Act. The goals and policies of this Official Plan are intended to be achieved by 2051.
The Official Plan provides the basis for Mississauga’s land use and urban design, in line with the City’s Strategic Plan. Its policies address important parts of city-building that affect everyone that lives and works in Mississauga, including transportation, housing, culture and heritage, the environment, and the economy.
The Official Plan also sets standards for the review and approval of development applications in the City.
Mississauga Official Plan 2051 was adopted by Council on April 16, 2025. It has subsequently been approved with modifications by the Ministry of Municipal Affairs and Housing (MMAH) on March 24, 2026.
An official plan consolidation of Mississauga Official Plan 2051, which will include the MMAH modifications, will be prepared. The office consolidation is prepared for the purpose of convenience only. For accurate reference, the original Plan as approved by MMAH, future Ontario Land Tribunal decisions and amendments to the Plan should be consulted.
Amendments that have been approved by Council as well as appeal activity since April 16, 2025, are outlined in the List of Unconsolidated Official Plan Amendments and OLT Decisions.
To understand the planning rationale and policy objectives of Mississauga Official Plan, it should be read in its entirety and all relevant text, tables and schedules are to be applied to each situation.
