Average Canadian gasoline prices are expected to soar this long weekend.
They've already jumped nearly 10 cents per litre since Hurricane Harvey roared ashore in Texas a week ago.
Analysts say the hikes will differ greatly by region, with prices in Eastern Canada jumping by as much as nine cents per litre over the weekend, while prices in Western Canada remain relatively stable.
Prices are expected to remain high until refineries on the US Gulf Coast return to normal operation, the timing of which will remain unknown until floodwaters recede and damage is assessed.
Prices began to spike when the storm knocked out about a fifth of the industry's refining capacity.
Gas prices as high as 132 cents per litre have been reported across Windsor-Essex.
