Gas In Saskatoon, June 3, 2016.

Friday was not a good day to buy gas in Saskatoon.  By Thursday the price had dropped to 101.9 cents a litre.  But Friday saw a large jump to 111.9 cents a litre at most locations.  This may be attributable to a shutdown of Suncor's Edmonton refinery, which provides gas to Petro-can stations in Western Canada, and those stations are expected to have shortages.
