Winter weather blasting the Maritimes has Prince Edward Island using up road salt faster than it can replenish the supply.

Darren Chaisson, director of highway maintenance on P.E.I., said supplies from Nova Scotia mines are limited.

"You know when you've got 30, 40 trucks hauling from here on a regular basis it doesn't take much to use that amount up," he said.

Chaisson said crews are spreading more than twice the amount of salt they usually do this time of year.

The storms in December made the province’s highways treacherous and slowed down salt transportation from neighbouring Nova Scotia.

"We're not the only customer hauling from Nova Scotia so we're basically just waiting in line and it's been a five or six hour wait at times over there for most of the last couple weeks,” said Chaisson.

The province isn't the only one feeling the strain. At Canadian Tire in Charlottetown, there's not a bag of regular salt to be found. 

"Salt seems to be the one that really took the hit, there's big demand everywhere as it seems -- across the country too now," said Steve Hennessey, manager at Canadian Tire.

Other winter supplies like scrapers, windshield wipers and shovels are also going fast.

"Everything’s is kind of sold out. Pretty much everywhere is kind of sold out now," said Canadian Tire customer Robin Gallant.

Hennessey said the store prepared for a regular December, in terms of weather, and P.E.I. didn't get one.

"Snow this early, it tends to skew the curve a little bit and you don't have quite what you thought you were going to have,” he said.

But there was some good news for transportation crews Thursday, the mine in Nova Scotia decided to stay open extra hours over the holidays.

"We're definitely more comfortable than we were last week for sure," said Chaisson.

He said next winter he won't have to worry about salt shortages because the province plans to make good use of its new and larger facility and fill it up over the summer.
