Current status
The proponent, James Dick Construction Limited (JDCL), will hosted their first public information meeting, virtually, on Dec. 6, 2023. This first public information session introduced the project, provide an overview of the Environmental Assessment Process, and to seek feedback on the preliminary criteria and indicators.
JDCL posted an update in May 2024, that included the RRRQEA Criteria & Indicators Response Table that outlined comments received from agencies and the public.
In July 2024, JDCL posted A Notice of Posting - Final Criteria & Indicators Package. In this package, the Consultation Overview of Criteria & Indicators Stage documents are available.
The second public information session was held on Nov. 19, 2025. The purpose of the meeting was to present and receive input on the draft comprehensive work plan and scope for technical studies that will be prepared to evaluate the effects of the project and the alternative methods of carrying out the project on the environment.
Project updates are available on JDCL's project website.
Provincial Environmental Assessment
On July 30, 2021, the Ministry of the Environment, Conservation and Parks designated the proposed quarry as an undertaking under the Environmental Assessment Act. This study places the proposed quarry into an additional approvals process through that Ministry as detailed in the Regulation approved by the Province.
The Ministry of Northern Development, Mines, Resources and Forestry have confirmed the Aggregate Resources Act process is on hold, awaiting the outcome of the environmental assessment process.
On Oct. 16, 2023, the Town of Milton received a formal ‘Notice of Commencement of Environmental Assessment (EA)’ from the proponent, JDCL. Halton Region, the Town, and Conservation Halton were invited to provide comments and input regarding the technical information produced by JDCL through the EA process. The Town will participate, as a member of the Joint Agency Review Team (JART), on the Government Review Team for the EA. The Town and other agencies are commenting bodies only and do not have any approval authority for the EA or overall ARA application
The requirements and process are summarized below:
- JDCL is required to prepare a number of specific studies pertaining to groundwater:
- Door-to-door well survey program;
- Water quality monitoring program;
- Assessment of the effect on groundwater from blasting below the water table;
- Any other hydrogeological studies that may be identified by the Director of the Ministry’s EA Branch:
- Fugitive dust study;
- Study of the conditions of any haul route(s); and
- A social impact assessment.
- Addressing cumulative effects in the environmental assessment
- Requirements for specific consultation in preparing the environmental assessment (e.g. notices, evaluation criteria and indicators, and a draft environmental assessment)
Unless specified in the regulation, the remaining provisions of the Act would apply to the quarry including ministry consultation on the environmental assessment, a published Ministry Review, and ultimately a decision by the Minister, subject to the approval of the Lieutenant Governor in Council, respecting an application for approval of an environmental assessment for the project.

Background
An application for a new quarry at 9210 Twiss Road, located west of the intersection at Reid Side Road and Twiss Road has been submitted to the MNRF by JDCL. No corresponding Planning Act applications have been filed with the Town of Milton or Halton Region. As a result, the Town of Milton is only a commenting agency to the MNRF and Milton Council is not the approval authority for the application.
The application proposes to reactivate the former Woodlawn Guelph Campbellville Pit that previously had its licence revoked by the MNRF in 2008.
JDCL has applied for a Class A Category 1 & 2 licence, covering approximately 29.4 hectares (73 acres) with an extraction area of approximately 25.7 hectares (63.5 acres) for sand, gravel, and bedrock. The maximum annual tonnage is proposed to be approximately 990,000 tonnes.
