Nova Scotia gas prices are typically set on Fridays and based on a seven-day average. There is an interrupter clause, however, that allows for changes at other times of the week due to a significant event. The board has traditionally resorted to using the interrupter clause for increases of at least six cents per litre of fuel. On Friday, the board issued a news release announcing it would invoke the interrupter clause and said the price of gas would change. 11th time for interrupter clauseSince 2009, the board has used the interrupter clause 10 times, with four of those occasions being for price increases.
