Building on watershed and prime agricultural land in northeast Pickering will have “catastrophic consequences” for the local ecosystem, a Sierra Club environmentalist is warning.

Pollution and flooding will result if Durham Region’s plan to develop the headwaters of Carruthers Creek goes ahead, Dan McDermott told reporters yesterday at the marsh off Audley Road S. in Ajax.


He is among a group of critics, including Ajax Mayor Steve Parish, working to change the region’s mind about converting 3,000 hectares of farmland, including 1,200 hectares in Pickering, to employment and residential use.

The Sierra Club’s research shows that “poorly planned infrastructure causes flooding,” McDermott said in releasing its Floods or Food report.
