Protecting Lanark Highlands from irresponsible aggregate development
April 16, 2026
Status of the Highland Line Pit Proposal:
A Case Management Conference has been scheduled for May 19. This is an early step in the Ontario land tribunal process where the case is organized, including who is involved, what the issues are, and how the process will move forward. Friends of Lanark Highlands is applying for Party Status so that we can fully represent the interests of our membership and the broader community throughout this process. We want you to know that we are aware of this development, we are following it closely, and we are working with our legal counsel to clearly understand the next steps. We will continue to keep you informed and will share further updates soon to help explain the process and what it may mean for our community.
Cavanagh Construction proposes a huge sand and gravel pit directly on the borders of Barbers Lake
A Class “A” pit operation with excavation below the water table operating 12 hours a day - 7 days a week (7 am to 7 pm)
Only a 30 metre setback from the sensitive wetland shores of Barbers Lake
Crushing, washing, and screening plants with recycling of imported construction waste and asphalt
Licence to remove up to 500,000 metric tonnes of aggregate annually
A truck every 2 minutes on the Highland Line, and continuing through Lanark Village to points east and south
The technical reports Cavanagh has submitted leave many unanswered questions about: traffic and roads; acoustics; the dark night sky; the impact on springs, aquifers, and wells; the impact on wetlands; loss of habitat and threat to species at risk; pre-contact archaeology; air quality;human health; property values; resource allocation; potential release of on-site uranium; climate change
In short, this proposal is an assault on the environment and the community surrounding McDonald’s Corners
Impacts
Removal and export of the entire hill forming the western shore of Barbers Lake
Potential destruction of important pre-contact artifacts
Loss of wildlife habitat in the vicinity of Barbers Lake and Long Sault Creek
Impact on property values and quality of life for waterfront and haul route communities
Damage to existing and future eco-tourism
Harm to water bodies through warmed water, potential contamination and silt
Threat to residents’ water supply, air quality, peace and well-being
Potential future demands, including a water taking licence, or permission to dewater
Aggregate is necessary for the growth and development of roads, housing and business!
Ontario has 13 times more aggregate than currently needed in already licensed pits
Misconceptions
This is revenue for the Township!
Lanark Highlands Township gets only 13 cents per tonne of aggregate taken away from the Township forever - in this pit the maximum payout possible would be $73,500 (14.7 cents x 500,000 = $73,500 per year), but likely much less - and MUCH MUCH less than the costs of road upgrades, loss of nature-based business and tourism, and the diminished value of properties throughout the area.

Proposed Sand and Gravel Pit on the Highland Line just south of McDonald’s Corners (in red)
The other sites in yellow are existing gravel pits. At present, none of these local pits operate below the water table.
