Milton's growth areas explained: Boyne, Trafalgar, Agerton, Britannia, Derry Green and the Education Village
Milton plans new neighbourhoods and employment lands through secondary plans. This guide explains what a secondary plan is and where each of the Town's six stands, according to the Town's own planning pages as of October 25, 2026.
The details
What a secondary plan is
Milton's Official Plan sets long-term goals for how land across the town is used. A secondary plan is a more detailed plan for one part of town. The Town describes its Britannia plan, for example, as establishing the area with a community structure, detailed land-use permissions and a policy framework. The Town's pages record the Boyne, Derry Green and Education Village plans each being adopted as an Official Plan amendment.
Some plans add one more layer. Under the Britannia and Trafalgar policies, a tertiary plan has to be submitted to the Town and endorsed by Council before any development applications for the area will be approved, and the Town says the tertiary plan is a landowner-led submission. The Town's Boyne page describes its tertiary plan as a way to coordinate services and infrastructure, road locations, the placement of schools, parks and village squares, and natural features.
Where each plan stands, as of October 25, 2026
- About 359 hectares between Highway 401, Derry Road, the Greenbelt and Eighth Line, centred on the area around a proposed Milton Trafalgar GO station. Council approved the plan on June 22, 2026. It comes into force and effect only after the Province approves Milton's new Official Plan.
- About 930 hectares between Louis St. Laurent Avenue, James Snow Parkway, Britannia Road and Tremaine Road, prepared to house 50,000 residents when fully implemented. Council adopted it on June 14, 2010, Halton Region approved it on September 6, 2013 and the Ontario Municipal Board approved it on January 7, 2015, apart from some site-specific policies that stayed under appeal.
- South and east of the Boyne area. Council approved the plan on January 27, 2025 and it came into force and effect on March 3, 2025. A landowner-led tertiary plan must be endorsed by Council before development applications for the area are approved.
- About 800 hectares of employment lands east of the Bristol Survey, between Highway 401, Sixth Line and James Snow Parkway. Council adopted the plan on June 14, 2010, Halton Region approved it on March 7, 2014, appeals were resolved by an Ontario Municipal Board order on April 2, 2015 and a consolidated version passed on November 9, 2015 with no appeals.
- Bounded by Derry Road to the north, Eighth Line to the east and the Greenbelt to the south and west; envisioned as a mixed-use, transit-supportive, higher-density community. Council adopted it on March 25, 2019, Halton Region approved it with modifications in September 2022 and the Ontario Land Tribunal fully approved it on July 22, 2024. Council endorsed its Tertiary Plan on December 8, 2025.
- A 162-hectare area centred on the Mattamy National Cycling Centre. Halton Region issued a Notice of Decision approving the Secondary Plan, with modifications, on June 26, 2024. See MiltonIQ's guide to the Education Village for the campus and what is approved.
Agerton's route to taking effect
Done: Study begins
The Town initiated the Agerton Secondary Plan in 2018.
Done: Statutory public meetings
Held in July 2022 and March 2026; the Town says the consultation period has ended.
Done: Council approval
Council approved the Agerton Secondary Plan on June 22, 2026.
Now: Provincial approval of the Official Plan
The Minister of Municipal Affairs and Housing decides on Milton's new Official Plan; the Town's pages did not report a decision on October 25, 2026.
Next: Secondary plan in force
Only after the Official Plan is approved, according to the Town.
Homes, jobs and the mix between them
Not every growth area is residential. The Town describes Derry Green as one of two planned employment areas under the Halton urban structure, while Boyne's tertiary plan covers the locations of schools, neighbourhoods, parks and village squares. Agerton is planned for at least 14,100 residents and 17,500 jobs, and the Milton Education Village for a mixed-use community of at least 22,000 people and jobs by 2051, including an innovation district for 2,900 knowledge-based jobs.
Who approves a secondary plan
The approving body has changed. Halton Region approved the Boyne, Derry Green, Trafalgar and Education Village plans. The Town's Official Plan page explains that on July 1, 2024 the Province identified Halton Region as an upper-tier municipality without planning responsibilities, so the Regional Official Plan is now treated as an official plan of each local municipality. Milton's new Official Plan, adopted by Council on June 22, 2026, goes to the Minister of Municipal Affairs and Housing for approval, and the Agerton plan follows it.
How to follow a growth area

- Check the Town's Official Plan page for the current consolidation and its maps and schedules, which show where each plan area sits.
- Watch for Planning Act notices of public meetings: the Town's pages record that Agerton's drafts went to statutory public meetings in July 2022 and March 2026.
