The race to replace Brenda Halloran officially has its first candidate.

Dave MacDonald filed his registration papers Friday morning at City Hall, joined by his wife and other supporters.

In an interview with CTV News, MacDonald said one of his top goals is to cancel Waterloo Region’s light rail transit project and put it to a referendum – despite claims from regional councillors that cancelling the project would carry a significant financial cost.

“I have been against the LRT, the way it’s been presented, from the beginning. I think it’s going to go way, way over budget,” he said.

“That’s the party line, that it would be cost-prohibitive (to cancel) – but is it more prohibitive to spend $200 million to kill a project, or to go $600 or $700 million over budget on the project?”

A longtime weathercaster at CTV Kitchener, MacDonald made his first foray into politics in 2011, running provincially in Kitchener Centre.

Representing the Progressive Conservatives, he lost a narrow decision to Liberal incumbent John Milloy.

Municipal elections take place Oct. 27 across Ontario.
