Well the price of gasoline just spiked upwards across Canada and the usual media analysis has begun. Five key reasons were summarized as follows by Shawn McCarthy in the Globe and Mail: 1) Approach of the summer driving season leading to a switch to summer gas formulations which leads to a reduction in supply. 2) Higher crude prices. 3) A lower Canadian dollar. 4) Lack of retail competition in Canada and 5) U.S. exports of gasoline and diesel out of North America creating tighter demand and supply conditions. I thought explanation number three was rather intriguing.
