On March 24, 2026, the Minister of Municipal Affairs and Housing issued a Notice of Decision to approve the plan. This means Mississauga Official Plan 2051 is now in effect, replacing the City’s former Official Plan and amendments. All new development applications will now be required to be consistent with the new plan.
What’s in Mississauga Official Plan 2051?
Mississauga’s new Official Plan sets a vision for the future of our City. It helps guide growth in a way that supports vibrant neighbourhoods, strong communities and a high quality of life.
The policies in the new plan aim to:
- Encourage more housing by allowing permissions for more than 370,000 new residential units city-wide by 2051, including more housing along transit corridors and gentle density in neighbourhoods.
- Create more mixed-use communities by connecting residents to the services and amenities they rely on most.
- Support job and economic growth by allowing for a broader range of uses in key employment areas, while protecting industrial uses from residential conversion.
- Enhance transportation options by expanding infrastructure for walking, cycling and transit to reduce congestion and improve connectivity.
- Strengthen environmental, cultural and heritage protections.
The Official Plan also outlines where development should occur and how essential services, infrastructure and amenities will come together to support a complete and livable city.
From vision to action
Under the Ontario Planning Act, the City is required to review and update its Official Plan every 10 years. The Official Plan review included extensive public engagement. City planners and staff heard from thousands of residents and businesses on key priorities, including housing, transit, job creation, heritage, diversity, infrastructure and environmental protection.
The Official Plan was adopted by City Council on April 16, 2025. It was then submitted to the Province for approval as required by the Planning Act.
The plan came into effect following the Province’s Notice of Decision; however, City staff are consolidating modifications issued by the Ministry as part of its approval. A final, consolidated version of the plan will be posted on the City’s Official Plan website in the coming weeks.
Mississauga’s new Official Plan will guide planning decisions across the City. It will help ensure growth is thoughtful, coordinated and aligned with the needs of residents today and in the future.
