Mineral Aggregates

Halton Region is home to a number of mineral aggregate operations - pits and quarries. Learn about policies, licensing and applications under review.

Mineral aggregates refer to pits and quarries that provide sand, gravel and bedrock used in roads and building construction. In 2016, there were 22 licensed aggregate sites in Halton Region. Most of the pits and quarries are located along the Niagara Escarpment.

Policies and licensing

Aggregate sites are licensed under the Aggregate Resources Act. The Halton Regional Official Plan contains policies that deal with public safety, environmental impacts, and the protection of natural heritage, agriculture, as well as ground and surface water.

Approval for new and expanded licenses

While the Ministry of Natural Resources and Forestry approves licenses for new or expanded aggregate operations, approvals from different agencies are required including:

Halton Region and the agencies review applications through a Joint Agency Review Team (JART) process. This team undertakes the technical review of studies submitted in support of aggregate applications such as:

  • Hydrogeology
  • Planning justification
  • Archaeology
  • Air
  • Noise
  • Blasting
  • Natural heritage
  • Cultural heritage and archaeology
  • Traffic

Together, the agencies share information and expertise, collaborate, and engage the public at early stages of an application.


Halton Region reviews applications for aggregate operations internal and external to Halton Region.

James Dick Construction Ltd. is proposing a new 39.4 hectare quarry within the Township of Guelph/Eramosa, on the north side of Highway 7, immediately adjacent to lands within the Town of Milton, and approximately 7.5 km west of Acton (Town of Halton Hills).

Applications to amend the Wellington County Official Plan and Township of Guelph/Eramosa Zoning By-law, plus a corresponding Aggregate Resources Act application, were submitted to those municipalities to permit a new Category 2, Class ‘A’ aggregate operation on these lands. Halton Region, the Town of Milton, and Town of Halton Hills participated in those processes as affected municipalities.

In July 2019, the Local Planning Appeal Tribunal (LPAT) hearing on the Aggregate Resources Act and Planning Act applications concluded. Halton Region is awaiting the decision on that hearing to determine any next steps.

In August 2018, the Region became aware of an Aggregate Resources Act application to the Ministry of Natural Resources and Forestry (MNRF) by James Dick Construction Limited (JDCL) for a new quarry at Reid Side Road and Twiss Road in Milton, to reactivate the former Woodlawn Guelph Campbellville Pit. JDCL has applied for a Class A Category 1 & 2 licence covering 29.4 hectares (73 acres) with an extraction area of 25.7 hectares (63.5 acres) for sand, gravel, and bedrock. The maximum annual tonnage is proposed to be 990,000 tonnes. No corresponding Planning Act applications have been filed. Halton Region, the Town of Milton, and Conservation Halton are participating in the Aggregate Resources Act application process managed by MNRF through a joint agency review team (JART) process.

In September 2018, the Region issued a Letter of Objection to the proponent and to MNRF (PDF file). The September 2018 Letter of Objection outlined twenty-four, high-level issues with the proposed application covering the following themes:

  • The potential effects of the operation of the proposed pit and quarry on the environment have not been adequately addressed
  • The potential effects of the operation of the proposed pit and quarry on nearby communities have not been adequately addressed
  • The suitability of the progressive rehabilitation and final rehabilitation plans for the site have not been adequately addressed
  • The potential effects on ground and surface water resources including on drinking water sources and private wells have not been adequately addressed
  • Detailed consideration should be given to planning and land use matters
  • Three miscellaneous issues

JDCL responded to Halton Region in a letter dated December 11, 2018. Staff provided an update to Halton Region Council at its meeting of March 27, 2019. The staff report provided a summary of the September Letter of Objection, as well as a reference map and JDCL’s reply to Halton’s September letter.

JDCL triggered a 20-day reply period in a letter dated April 29, 2019 (PDF file). Halton Region provided a reply letter within that period (PDF file), identifying that objections raised in September 2018 had not been resolved.

Halton, Milton, and Conservation Halton provided detailed comments through JART review to JDCL and MNRF on July 31, 2019. The cover letter summarizing key thematic issues with JDCL’s submission was supplemented by a detailed comment table prepared by staff and retained consultants.

JART staff from Halton Region, the Town of Milton and Conservation Halton has been assessing updated information that JDCL provided JART members as a response to their individual objections. JART has met with the proponent and are investigating the range of issues and objections raised by the organizations through the JART review process. This has resulted in updated information being posted to the proponent’s public website and a number of alterations to the proposed quarry, including a reduced scale of extraction and mitigation and contingency measures for quarrying. Conservation Halton, Town of Milton, and Halton Region continue to have ongoing objections to the proposed quarry as noted in their objection and response letters. Conversations with the proponent are ongoing as mandated by the Aggregate Resources Act (ARA).

Halton Region awaits next steps from either JDCL or MNRF on the continued review of this application.

JDCL has now added an application update to their website. For a list of the original studies and application updates, please visit their website.

Previous Application          

In 2004, and revised in 2006 and 2008, Nelson Aggregates filed applications to amend the requesting a Regional Official Plan to re-designate lands and permit expansion to the south of the quarry.  At its meeting in October 2009, Regional Council did not support the Regional Official Plan Amendment application and advised the Joint Board. In 2012, the Joint Board Hearing denied the application.

The following reports relate to the applications made during that time period:
