As OC Transpo laid out a plan to restore double-car service on the LRT this April, Alta Vista Coun. Marty Carr asked who was paying for it.

Associate general manager Troy Charter gave a clear answer: Rideau Transit Group (RTG), the private consortium that built and maintains the system.

"They are responsible for anything and everything to do with the design, the build, the maintenance of the system," he said at a transit committee meeting. "If there is a latent defect, a construction-related defect, that is their cost to bear to fix."

But it turns out that RTG didn't bear the cost of a key part of that plan. Taxpayers did.
