B.C. Conservative Leader John Cummins says his party would create a tax credit for people who regularly pay bridge tolls or ferry fares.

The proposal is the first plank of his party's platform for the upcoming May 14 provincial election.

The tax credit would be for people paying more than $780 per year on tolls and ferry fares. It would cover 40 per cent of the cost to a maximum credit of $408.

"The only British Columbians who must pay tolls are those live and work in specific areas of the Lower Mainland and who use the Port Mann or Golden Ears Bridges to drive to and from work, and that is unfair," said Cummins.

"What we're trying to do is to address that hit that these average families are taking and give a little bit of that back. We think the hit is simply too big it's unfair these folks are the only ones paying the toll."

Cummins says the tax credit would cost the province $45 million in lost revenue each year.

Currently there are two tolled bridges in Metro Vancouver: the Port Mann Bridge and the Golden Ears Bridge.
