Part II Order Request Process

The Class Environmental Assessment (EA) process provides an opportunity for the public and other stakeholders to appeal the Class EA process undertaken by the Study Team. Under the provisions of subsection 16 of the amended EA Act, there is an opportunity under the Class EA process for the Minister to review the status of a Study. Members of the public, interest groups and review agencies may request the Minister to require a proponent to comply with Part II of the EA Act, before proceeding with a proposed undertaking. This is known as a “Part II Order” (formerly called “Bump-Up Request”).

The procedure for dealing with concerns that may result in the Minister, by order, requiring the proponent to comply with Part II of the EA Act is outlined in the Class EA document. It is anticipated that all concerns will be resolved through discussion between the Town and the concerned individual(s) or group(s). As of July 1, 2018, a Part II Order Request Form must be used to request a Part II Order. The Part II Order Request Form is available on the Forms Repository website by searching “Part II Order” or “012-2206E” (the form ID number). 

Public Information Centre

On July 5, 2018, a Public Information Centre (view the public notice) was held for the environmental assessment for the widening of McLaughlin Road, and the construction of the new east-west Spine Road from Hurontario Street to Chinguacousy Road. Materials included poster boards and the following recommended designs:

May 25, 2017: The Ontario Municipal Board issues a decision on Official Plan Amendment 222.

On March 8, 2016, the Transportation Master Plan was presented to Council.

On March 8, 2016, the Community Design Plan was presented to Council.

The Mayfield West Phase 2 Secondary Plan Official Plan Amendment, OPA 222 was adopted by Council on November 10, 2015. 

At a Council Meeting on December 20, 2016, Council adopted the following recommendations with respect to Mayfield West Phase 2 Secondary Plan:

  • Whereas the Town of Caledon Official Plan directs future growth to Bolton and Mayfield West with Mayfield West to grow faster than Bolton until they become similar in size; and
  • Whereas Mayfield West Phase 2 Secondary Plan General Terms of Reference was endorsed by Council on June 10, 2008 to strategically identify a location in Mayfield West for growth for the planning period from 2021 to 2031; and
  • Whereas a preferred scenario for the Mayfield West Phase 2 Secondary Plan was endorsed by Council on August 10, 2010 that includes lands south of the Etobicoke Creek, west of Highway 10, north of Mayfield Road, and east of Chinguacousy Road; and
  • Whereas the Mayfield West Phase 2 Secondary Plan has always targeted at building a compact and complete community that far exceeds the Greenfield density target set by the Province; and
  • Whereas the Mayfield West Phase 2 Secondary Plan was forced to split into two parts with only the east side, approximately 206 hectares of developable land, approved to proceed under ROPA 29 in order to achieve Region-wide intensification and Greenfield density targets; and
  • Whereas the province has since adjusted its 2031 growth forecasts with an increase of 130,000 persons and 10,000 jobs for Peel Region, and Peel Region has not made its adjustments accordingly; and
  • Whereas the subject land is entirely inside the area in Peel Region Official Plan (section and Schedule D) that is designated for future growth; and
  • Whereas most studies required to amend Peel Region's Official Plan for a settlement area boundary expansions have been completed through Mayfield West Phase 2 Secondary Plan on the basis of compact and complete community building; and
  • Whereas all required Regional servicing capacities, including road, water and sewer, have been either in place or planned to be in place in the next two years to support a complete community building in Mayfield West Phase 2;
  • Now therefore be it resolved that the Region of Peel be requested to amend its Official Plan to bring the remaining area of the Town of Caledon Mayfield West Phase 2 Secondary Plan into settlement area; and
  • Further that staff be directed to review, validate and update, where needed, all the studies that have been completed in the area to meet the requirements of Peel Region Official Plan for a settlement area boundary expansion; and
  • Further that staff be directed to prepare a new Planning Justification Study Report, as well as other studies that may be deemed necessary by Peel Region Official Plan, to support the Regional Official Plan Amendment;  and
  • Further that staff be directed to continue to work with staff from the Region of Peel and the Mayfield West Phase 2 Landowners Group to expedite the planning process.

Mayfield West: Introduction

Located in the southwest part of the Town of Caledon, the Rural Service Centre of Mayfield West is being planned by the Town as a compact, vibrant, well integrated community through a series of phased settlement boundary expansions. The first such expansion occurred through the Mayfield West Community Development Plan (Official Plan Amendment No. 208) which was endorsed by Town Council on July 4, 2006 and approved by the Ontario Municipal Board on October 1, 2007.

Population and Employment Forecasts

The Town has revised the population forecast for Mayfield West for 2021 from 13,100 to 17,000 (the population increase of 3,900 has been reallocated from elsewhere in the Town) and allocated a further 9,838 population to Mayfield West for the planning period 2021 to 2031.

Mayfield West Phase 2 Secondary Plan (MW2)

In 2008, the Town initiated MW2 to determine, among other things, the appropriate location in Mayfield West for the population growth outlined above. On June 10, 2008, Town Council approved general terms of reference for MW2 which, among other things, provide details about what the planning exercise will achieve, the time it will take do be completed and how and when the public can provide input.

In addition to planning for the population growth outlined above, MW2 is also planning for new employment lands to accommodate approximately 5,895 new jobs, approximately 935,000 sq. ft. of commercial uses, and new community parks, schools, public open spaces and a twin-pad ice arena to support and complement the population growth. Implementing these planning considerations will require an expansion to the existing 2021 Mayfield West settlement boundary.

In keeping with the Town of Caledon Official Plan, settlement boundary expansions in Mayfield West will occur within the Mayfield West Community Development Plan Study Area, a study area which is established in the Town's Official Plan on Schedule B - Mayfield West Land Use Plan.

In April 2009, Town Council approved revisions to key milestone events in the MW2 work program and schedule.

Sustainable Community Planning

The Town has retained NAK Design Strategies to undertake a comprehensive community vision and design study for Mayfield West Phase 2. This study was presented to Council on March 8, 2016.

The Provincial Growth Plan

With the introduction of the Growth Plan, the Province has engaged new thinking in respect of the way growth occurs in the Greater Golden Horseshoe area and the Regions within it, including the Region of Peel. Part of this new thinking is an emphasis of developing greenfield communities which are compact, integrated and more sustainable.

One of the key objectives of the Growth Plan is to minimize urban sprawl and promote cost-effective development. This has led to an increased emphasis on achieving higher densities for both population and employment to reduce land consumption and to promote greater use of existing infrastructure. Under the Growth Plan, new development taking place in designated greenfield areas must be planned and designed in a manner that contributes to creating complete communities. The Growth Plan defines complete communities as:

"Complete communities meet people's needs for daily living throughout an entire lifetime by providing convenient access to an appropriate mix of jobs, local services, a full range of housing, and community infrastructure including affordable housing, schools, recreation and open space for their residents. Convenient access to public transportation and options for safe, non-motorized travel is also provided."

Guiding Principles

In May 2009, Town Council endorsed nine guiding principles for MW2 through Report PD-2009-029. The nine guiding principles are:

  1. Achieve net ecological gain, when practical, possible and advisable.
  2. Adopt an integrated design process.
  3. Foster a local identity rooted in the spirit of the Town of Caledon.
  4. Establish the structure for a close knit small town that fosters self sufficiency.
  5. Achieve a range and mix of housing.
  6. Promote walking, cycling and transit opportunities.
  7. Maximize conservation and innovation (water, waste, energy).
  8. Ensure community connectivity and integration at all scales.
  9. Support adaptive change.

The principles provide the basis for defining and confirming the overall direction for MW2, reflecting the collective interests, aspirations and desires of a broad range and mix of interests including agencies, advisory committees of Town Council, stakeholders, landowners and residents. Given this encompassing mandate, the principles are broad in nature. They have "set the bar high", challenging all parties to push the boundaries of their own experience, reconsider other's points of view, and collectively define a plan for MW2 that is as good as it can possibly be.
