The Government of Ontario has formally approved Mississauga’s new Official Plan.

The Minister of Municipal Affairs and Housing issued a Notice of Decision to approve the plan on March 24. The decision means Mississauga Official Plan 2051 is now in effect, and all new development applications will now be required to be consistent with the new plan.

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.

“This is a proud moment for Mississauga as our new Official Plan is approved and the review process comes to a close,” said Andrew Whittemore, the city’s commissioner, planning and building. “I’m confident that as development moves forward in line with this plan, it will help strengthen our economy, protect our environment and create a more complete, livable city for generations to come.”

Under the Ontario Planning Act, the city is required to review and update its Official Plan every 10 years. This latest edition of the plan was adopted by City Council in April 2025, and was submitted to the province for approval.
