As of Thursday morning, Halifax residents are now paying a minimum of 192.9 cents for regular self-service, according to gas price aggregator GasBuddy. "This change is necessary due to significant changes in gasoline and diesel market prices," the Nova Scotia Utilities and Review Board said in a statement.

Residents of Cape Breton Island pay the most for gasoline in the province, sold at 194.9 cents per litre.

The cost of diesel also fell Thursday to 204.7 cents per litre, down 10.2 cents. Prices now range from $1.94 per liter in the Halifax area to a minimum of $1.99 per liter in Cape Breton.

The interruption clause is a mechanism that allows the utility and the review board to adjust gas prices in response to market fluctuations outside of the weekly price change. The last time the province invoked it was on June 21, to cut the price at the pump by six cents.
