Meanwhile in Montreal, the price is expected to peak at as much as $1.42 per litre at some point over the Labour Day long weekend.
Dan McTeague, senior gas analyst at GasBuddy.com, calls it "the Hurricane Harvey Effect" as the storm has a major pipeline and 16 refineries in the United States offline.
Overnight, Montreal gas prices went up 10 cents to $1.26.9/litre of gas, reports CBC.
The retail price for regular self-service gasoline increased 7.4 cents a litre at midnight Thursday, due to rising prices on North American energy markets caused by supply shortages brought about by refinery shutdowns in Texas.
Wholesale gasoline and jet fuel prices have soared as at least 4.4 million barrels per day of refining capacity, or almost 24 percent of total USA capacity, has been closed due to the record rains.More news: Pokemon GO Plus Now Spins On Gyms

According to Gasbuddy retail prices spiked between Monday and Wednesday from about 94.8 to over 103.2 at the time of publication.
McTeague offered a look at what the country could expect in the coming week.
And industry experts think the prices will stay inflated through mid-September, rather than falling off right away.
Roger McKnight, senior petroleum analyst with En-Pro International Inc., said he has never seen such a big price increase. "And simply because buyers in the States would be looking to Canada for supply, we're seeing higher wholesale prices in Eastern Canada, as well", Ervin said. "In Canada, we barely produce enough gasoline to meet our own needs".
Nova Scotia gasoline prices are set to go up again Friday at midnight, just 24 hours after the weekly gas price was established by the provincial regulator.
