Expert worries carbon tax could force New Brunswickers across border for cheaper gas

An expert is predicting the federal carbon tax could push New Brunswick motorists across the province's borders looking for cheaper gas.

New Brunswick gas prices jumped by more than four cents a litre Monday, as Ottawa imposed a tax on four provinces that refused to impose their own emissions pricing.

Prices rose 4.42 cents per litre plus HST for gas in New Brunswick.

Diesel jumped 5.37 cents per litre, and home heating fuel jumped 5.37 cents per litre.

Provincial Environment Minister Jeff Carr said New Brunswick, the only Atlantic province with an imposed tax, is being hit with the region's highest carbon gas tax.

The province said PEI is paying just a penny more per litre of gas in carbon tax, and it's less than half that in Newfoundland and Labrador.

Nova Scotia is also estimated to face an extra penny per litre.

Carol Montreuil of the Canadian Fuels Association said motorists are ``very sensitive'' to prices, and rising costs could potentially drive New Brunswick over nearby provincial borders for cheaper fuel.
