Excerpt from "Just Sayin' Caledon" 12/29/25:
"Whitchurch-Stouffville believed it was acting responsibly in the early 2000s when it adopted a fill bylaw intended to manage excess soil in a controlled and limited way," said soil biologist and former Whitchurch-Stouffville councilor Mark Carroll. "What followed instead should serve as a cautionary lesson for Caledon. What began as a single, tightly framed fill approval for small property owners has grown steadily and contentiously into the aggregate business. One site became two, then more, and today we are dealing with five ongoing professional fill operations – many with no clear end dates."
Eighth Line at Barbour Field (Truck Haul Route) - May 24, 2026
Background
Background
In January 2026, Erin Council approved a 20-year Site Alteration Agreement for a large-scale commercial fill operation at 9516 Sideroad 27, Hillsburgh.
The agreement runs until December 31, 2045, allowing importation of about 5.36 million cubic metres of fill.
A public meeting was held to discuss the Site Alteration proposal in July 2024, however most neighbouring residents were not made aware of the meeting. Those that were able to attend and speak were not listened to.
Designated Haul Route
Who is Affected?
Who is Affected?
Fill can be brought in from all over Ontario. Anyone living on or commuting via the designated truck haul route will be affected. Routes include 27th Sideroad, Eighth Line, 22nd Sideroad, Trafalgar Road (north and south of Hillsburgh) and Winston Churchill. Ross R. MacKay Public School, Barbour Field, and the Hillsburgh Community Centre are all along the designated truck routes.
Pit Fill Operation Concerns
Pit Fill Operation Concerns
Risk of groundwater (& well) contamination
Traffic congestion & noise
Dust, rocks & cracked windshields
Road capacity and road safety
Potential for contaminated soil & ground water
Truck haul route shared with school buses
Close proximity to sensitive watershed and fish habitat and hatchery
Impact on existing plant, animal and fish species that inhabit the land and pond
Is this Commercial Fill Operation in the best interest of the people of Erin? Pit rehabilitation projects like nearby Swan Lake and Pinchin Pit in Caledon show how properly rehabilitated pits can benefit the entire community.
How will this operation affect the construction and operation of the new recreation facility at the intersection of Eighth Line and 22nd Sideroad?
With an additional 150 dump trucks an hour heading south on the Eighth Line from the pit, traffic lights and potentially new turn lanes will likely be needed, as well as turn lanes at Trafalgar road and 22nd Sideroad. Who will be paying for these?
Has council thought beyond the $10 million?
Transparency & Process Concerns
Transparency & Process Concerns
The Erin Citizens' Coalition came about as a result of our shared frustration with trying to understand how the Hillsburgh Pit Fill operation was approved. Below are some of our shared concerns:
Why did no one receive the required notice of the July 2024 public meeting? Notices were required to be sent to residents within 120 metres of the pit?
Why is there no requirement to notify residents on the truck haul route, given the scale and 20 year duration of the project?
Why was there no public meeting to receive public input on the passing of by-law amendment (16-30), which paves the way for similar large scale, long-term, site alteration projects in the future?
What are the potential current and future ramifications of by-law amendment (16-30) on Erin residents?
In past council meetings there is repeated reference to an MNR standing order to "fill the pit". The ECC has confirmed that there is no such order. Is council aware of this and why didn't they do their due diligence to confirm this and other information presented by the land owner/applicant?
Is the Earth Healing Foundation involved in the project as indicated by the signage on the property? The timelines for rehabilitation on their website varies drastically from what was approved.
What is the future end use of this property? Some documents say agricultural. Others say end use is residential. Others say recreational. Others say commercial (?) Refer to Appendix A, Site Alteration Agreement, Recommendation Report - Agreement for Site Alteration Permit, and the Notice details documents on the Excess Soils website.
