Nova Scotia's regulator invoked the interrupter clause to reduce the price of gasoline in the province by six cents. The scarcely-used mechanism is employed when the daily market price for refined gas swings wildly between six to eight cents a litre before the province’s weekly gas price is set. Pump prices on the South Shore are now sitting at $1.373 cents a litre, down from $1.43 a litre on Wednesday. The pump prices, usually changed every Thursday at midnight.
