When his neighbours first talked about suing the provincial government to stop the Site C dam, Ross Peck had his doubts.

“I must admit, when we made the decision to go this route, I was a little apprehensive,” said Peck, who lives in the Peace River Valley. But after a morning of arguments in a Vancouver courtroom, those apprehensions washed away.

“It made me feel good,” he said. “This is probably our last chance [to stop Site C], and I think it’s very important we put forward our views.”

The first of seven lawsuits aimed at blocking Site C made its way before the B.C. Supreme Court Monday.
