I asked gas station owners, petroleum industry associations, economists, analysts, and as many consumers as I could find but no one could provide with a satisfactory answer about why gas prices in my market --- the Toronto area -- or in Montreal, Halifax, Winnipeg, and other major Canadian cities are bouncing around with such big swings. Gas in Toronto was 70.9 cents a litre Monday at lunch. Tuesday at lunch it was at 80 cents. In Winnipeg, one consumer said she bought gas Monday for 64 cents a litre and on Tuesday it had popped to 78 cents a litre. Meanwhile, the in the U.S., gas prices are hitting record-highs -- the average tracked by the American Automobile Association came in at over $1.73 a gallon yesterday -- and some commentators are warning it could go to $3 (U.S.) a gallon. All of this prompted a piece I did last night for CTV's national newscast. You'll have click on the "Related Video" link on the right of the story at that site to watch the piece.
