CAUSE is a not-for-profit corporation that was created by a coalition of community-based organizations that are alarmed by the threat confronting communities in Dufferin County and beyond as a result of the Mega Quarry proposal.

CAUSE has aggressively challenged the Mega Quarry bid and is proactive in all aspects of the approvals and review processes that have been initiated by this ill-conceived proposal.


Our focus is to provide strategic technical and professional support to those interested in protecting the natural integrity of the Hills of the Headwaters area and promote livable and sustainable communities in east Dufferin County. The proposed mega quarry has far-reaching consequences that have already compromised those objectives, prompting greater vigilance and direct participation in government review processes by those that value the water, soil, people and natural beauty that characterize this area.

The company proposing Canada’s first and largest Mega Quarry is made up of local speculators backed by a multi-billion dollar hedge fund out of Boston called Baupost Group. After gaining control over about 8,500 acres of prime agricultural farmland about 100 kms north of Toronto, they now want government permission to blast, dig and extract unlimited tonnages of limestone by creating a crater 2,300 acres in size and 200 feet deep.

In March 2011, The Highland Companies filed applications with the Township of Melancthon and the Ontario government seeking approval to develop a below-the-water table limestone MEGA QUARRY 2,300 acres in size and up to 200 feet deep.
