South East Milton Urban Expansion Area

Agerton Employment Area and Trafalgar Corridor Secondary Plans


As part of the approval of Regional Official Plan Amendment (ROPA) Number 38, additional lands were identified in the Town of Milton to accommodate population and employment growth from 2021 through to 2031. 

Referred to as the "Sustainable Halton Lands", the lands identified for growth will serve as Milton's next urban expansion area and next major Secondary Plan Areas. These lands are located in the south and eastern portion of the Town of Milton and encompasses approximately 2000 hectares (5000 acres). 

The Sustainable Halton Lands are required to meet minimum density and employment targets established in the Province's Growth Plan for the Greater Golden Horseshoe, as well as the Region of Halton and Town of Milton's growth strategy.  Comprehensive planning of these lands will enable the Town to achieve the required population target of 238,000 persons and employment target of 114,000 jobs across the Town by 2031. 

In order to gain a better understanding of some of the key opportunities and constraints to developing this area, the Town of Milton has initiated two key background studies - a Subwatershed Study and a Land Base Analysis. 

Subwatershed Study

The study area for the Subwatershed Study goes beyond the identified urban growth area and includes subcatchments of the main, east and west branches of Sixteen Mile Creek.  The entire SWS study area encompasses approximately 5260 hectares (13000 acres). 

The Subwatershed Study is intended to assess environmental features and functions within the study area and to provide recommendations for the protection and management these features as part of future planned development.

The purpose of the Subwatershed Study is to:

  • inventory, characterize and assess natural hazard, natural heritage and water resource features and functions within the study area (i.e., constraints to development);
  • provide recommendations for the protection, conservation and management of natural hazard, natural heritage and water resource features within the study area;
  • provide sufficient detail to support the designation of Natural Heritage System, through refinement of the Regional Natural Heritage System, as well as identifying areas for future development; and
  • provide recommendations for a management strategy, implementation and monitoring plan to be implemented through the Secondary Plans and future site/area specific studies. 

The Subwatershed Study is being conducted under the Environmental Assessment (EA) Act to satisfy the requirements of the Municipal Engineer's Association Class EA process.  The study will satisfy Phases 1 and 2 of the Class EA process and any municipal projects recommended as part of the plan will have their schedule and specific approval/implementation requirements identified.

The Subwatershed Study process has been structured to be carried out in four phases, which will result in three or four documents/reports, including:

  • Phase 1 - Background Review and Characterization;
  • Phase 2 - Analysis;
  • Phase 3 - Management Strategies; and
  • Phase 4 - Implementation and Monitoring.

The Subwatershed Study commenced in Winter 2016 and is anticipated to take approximately two years to complete.  A Draft Phase 1: Background Review and Characterization Report was prepared and released at the end of March 2017. 

The Subwatershed Study must ensure that all applicable Provincial, Regional and Town land use planning requirements, including conservation authority regulations, are achieved.

The Subwatershed Study is to be completed prior to the approval of any Secondary Plans for the Sustainable Halton Lands.  It is to provide technical support to the Secondary Planning process and is to outline the preferred stormwater and environmental management strategy for the Secondary Plan Area. 

Land Base Analysis

The study area for the Land Base Analysis is primarily centered on the identified urban expansion area; however, some of the background work associated with this study considers land beyond the urban expansion area (e.g., agriculture component or transportation component).

The Land Base Analysis is intended to identify the key opportunities and constraints to development, as well as inform and provide direction to future Secondary Planning processes.

The purpose of this Land Base Analysis is to:

  • identify key opportunities and constraints to development;
  • assess and  approximate the amount and distribution of unconstrained land that is available for development;
  • assess the feasibility of developing the area including, but not limited to, a preliminary assessment of the potential public infrastructure needed to facilitate development;
  • delineate logical and cohesive Secondary Plan Area(s); and    
  • provide a framework/approach that can be used to guide future studies and phasing for the Secondary Plan process.

The Land Base Analysis commenced in late Fall 2016 and was presented to Council on September 25, 2017.   The Land Base Analysis was finalized in November 2017. 

The Land Base Analysis will serve as the basis and background for the preparation of future required Secondary Plan studies.  This study is not intended to be a detailed analysis; rather, it is meant to serve as one of the initial background steps in the Secondary Plan process which can be used to provide direction and guidance for the planning process.

Ultimately, the Secondary Plans will establish a more detailed planning framework for the Sustainable Halton lands, building upon the general framework provided for in the Town and Region's Official Plan.  The Secondary Plans will also establish policies that will result in a complete, healthy, and sustainable community(ies).  The Secondary Plans will implement the Natural Heritage System and management framework established via the Subwatershed Study.

Secondary Planning Program for Sustainable Halton Lands 

On September 25, 2017, Town Council received two reports related to future planning and growth in the Town of Milton (i.e., PD-048-17 and PD-049-17). 

Staff Report PD-048-17 provided an overview of the key findings and recommendations of the Land Base Analysis, as well as the next steps for the Town as it relates to the Secondary Plan program for the Sustainable Halton Lands.  Town Council endorsed, in principle, the draft Land Base Analysis.  Among other things, the Land Base Analysis provided a number of recommendations related to the delineation of Secondary Plan Areas, a high-level community/neighbourhood area structure plan, as well as criteria for prioritizing the sequencing of each Secondary Plan Area. 

Map 2 depicts the three Secondary Plan Areas presented in the Land Base Analysis, which includes the 'Agerton Employment Secondary Plan Area', the 'Trafalgar Corridor Secondary Plan Area', and the 'Britannia East/West Secondary Plan Area'.  It also shows conceptually how each Community Secondary Plan Area could be divided into "neighbourhoods", as well as a high-level structure plan, comprised of potential corridors with transit terminating at a GO station and community nodes.   A summary of the anticipated characteristics, structure, and targets for each of these areas is discussed further in Staff Report PD-048-17.

Staff Report ES-013-17 outlines the Town's preferred direction for a Secondary Planning program for the Sustainable Halton Lands and recommends concurrent commencement of a Secondary Plan process for the Britannia East/West, Trafalgar Corridor, and Agerton Employment Secondary Plan Areas.  Staff Report ES-013-17 was endorsed by Town Council on October 30, 2017 and it is anticipated that a Secondary Planning program will formally commence in early 2018.
