Hurricane Harvey's aftermath could hike gas prices by 15 cents in some Canadian cities

Massive flooding in southeast Texas has already impacted gasoline prices in the surrounding area, and one expert says the same could soon happen in Canada.

Massive flooding in southeast Texas has already impacted gasoline prices in the surrounding area, and one expert says the same could soon happen in Canada.

Hurricane Harvey's remnants left much of Houston underwater on Sunday, and the National Weather Service says it's not over yet: Some parts of Houston and its suburbs could end up with as much as another 1.3 metres of rain.

The storm has affected about 2.2 million barrels per day of refining capacity in the United States, including ExxonMobil, Shell and Phillips 66 operations that began shutting down Sunday.

"They are not making gasoline, they're not making diesel fuel," said Randy Ollenberger, managing director of BMO Capital Markets, "so that's tightening up those markets not only here in North America, but globally because the United States was exporting both gas and diesel to Europe and South America."

And Canada too, which is why gasoline prices that have jumped about seven cents a litre in a week may come north next.

Depending on how long refining capacity is out for, the impact on Canada could be even worse, says Dan McTeague, senior petroleum analyst with price comparing website

"Hurricane Harvey's associated flooding and longer than expected stall over the Texas refinery row is likely to see steep price hikes at the pumps across North America for the next few weeks," McTeague said.

"With a portion of total U.S. gasoline production shut in due to the prolonged effects of Hurricane Harvey, Canadians should expect a noticeable increase beginning this Wednesday."

Up to 15 cents a litre in Montreal

Vancouver, Victoria and most of B.C. should expect a hike of about three cents a litre, while Calgary, Edmonton, Regina, Saskatoon and Winnipeg may see prices rise three to eight cents a litre

Toronto and most of Ontario are in store for a five-cent hike, while Montreal may see the biggest jump — as much as a 15-cent increase to about 127.9 cents a litre by mid-week.

"For the Maritimes and Newfoundland, which follow last week's prices under their regulated price regimes, a five cent a litre increase should be expected with the possibility that their 'interrupter clause' may be deployed before Thursday and Friday," McTeague said Monday.

Broader impact

Beyond pump prices, the storm has the potential to take a bite out of the North American economy, if the heavy hit to the energy sector spreads — and lasts.

"I'm not sure if we can really quantify how much that will be right now," Ollenberger said. "It really depends on the duration, but it will have an impact.

"The longer this goes on — in terms of these outages — the bigger the impact will be."
