Commercial vehicles aren’t the only ones mistakenly getting double-billed on the Highway 407 Express Toll Route.

Andrew Bell told CTV News he’s been double-billed after driving on the 407 while towing a personal watercraft.

“Same date, same time and same number of kilometres billed to both,” he said.

He contacted the 407 and they revoked the duplicate charges. While the 407 insists double-billing is rare, Bell said it always happens to him when he’s towing his watercraft.

“I thought, well, based on my experience, the limited number of times I go on the 407 with the trailer, it’s happened to me every time,” he said.

The 407 has two ways to check for vehicles using its highway: either via a registered transponder or by photographing a licence plate.

On Monday, CTV News reported that commercial tractor-trailers were sometimes mistakenly billed as two separate vehicles -- one charge for the truck’s transponder, and another for the licence plate on the trailer.

Progressive Conservative MPP Jim Wilson said it’s time for the 407 to overhaul how it tracks drivers.

“Obviously what they’re doing isn’t working when people fall through the cracks like that, so they need to review the situation and come back to us and tell us what the options are,” he said.
