Drivers across Toronto and the GTA will see a nine‑cent drop at the pumps on Friday, with prices falling to 180.9 cents per litre, according to the latest forecast from Roger McKnight, chief petroleum analyst at En‑Pro International.The decrease takes effect at 12:01 a.m. Friday, but McKnight says the sharp drop doesn’t align with market conditions.“Going by the closing futures markets… prices [Friday] should increase by one cent. The nine‑cent decrease in the east and [five-cent decrease] in Vancouver make no sense and may be corrected later today,” he said.Related:Toronto, GTA gas prices set for 8‑cent drop Friday amid seasonal fuel switchFriday’s drop comes less than 24 hours after gas prices rose six cents on Thursday — a move McKnight attributed to wholesale market pressures.
