 When this was first brought about many including in the New Democratic Party and the Retail Gasoline Dealers Association of Nova Scotia wanted a system similar to Prince Edward Island for lower prices.The ones opposing this scheme argued that the PEI system not only keeps prices higher but it does not allow for competition.The lower gasoline prices are a result of PEI's not charging the Provincial Sales Tax of 10% unlike in Nova Scotia where the Harmonized Sales Tax of 15% is charged.
