A gas shortage continues across Nova Scotia, with many stations reporting they are completely out of regular, supreme and diesel fuels.

The shortage was caused by a delay in getting fuel to the Dartmouth terminal, says Merle MacIsaac, a spokesperson for Imperial.

Two delivery ships were delayed in arriving in Dartmouth last week. They finally arrived on Friday and over the weekend. MacIsaac said he did not know exactly why the ships were delayed.

"What's happening now is that these vessels are being discharged," said MacIsaac on Sunday afternoon.

"Their product is undergoing a process of settling, testing, and treatment before they're ready for release to customers. So we expect now to make that supply available to customers by mid-day tomorrow."

MacIsaac said trucks containing regular fuel are expected to hit the road to start making deliveries by mid-day Monday.

Trucks with supreme will take several days longer before they can start making deliveries.

CBC Nova Scotia called a sampling of gas stations around the province to find out the situation as of Sunday afternoon.
