A gas shortage persists in Edmonton more than two weeks after many Petro-Canada pumps went dry.

And it's not just Edmonton's pumps that are covered in yellow tape — gasbuddy.com analyst Dan McTeague said there could be as many as 200 stations in Western Canada sitting empty.

The shortage was caused by a recent unplanned outage at oil giant Suncor's Edmonton refinery, and oilsands production shutdowns caused by the Fort McMurray wildfire.

Until they get a lot of their production back online, it's not likely that we're going to see an end to yellow tape. - Dan McTeague , gasbuddy.com analyst

The company planned to have the production issues sorted out this past weekend, but many Petro-Canada stations remain without gas.

"Until they get a lot of their production back online, it's not likely that we're going to see an end to yellow tape," McTeague said.

Sneh Seetal, a spokeswoman for Suncor, Petro-Canada's parent company, said they're doing their best to get gas to pumps during summer driving season.

"We're working to replenish sites as quickly as possible," Seetal said in an email.

"This can take some time, but we have a team dedicated to the situation and we're using all the logistics available to us – moving product by truck, rail and pipeline."

At least 200 gas stations affected

McTeague said the refinery that went down processes 140,000 barrels of oil a day and supplies gas to cities in interior British Columbia and as far away as Thunder Bay, Ont.

The longer it takes Suncor to resume operations, the greater the impact on the company's revenues.

"The likelihood is there has been at least 200 stations affected or more, and of course that will mean some serious catching up to do by Suncor, given the large area which that refinery covers," McTeague said.

Any major increase in gas prices has more to do with supply from the U.S., he said, where supply is dire and demand continues to be very high.

In the meantime, McTeague said Suncor will likely have to buy gasoline from other producers, which will come at a premium.

Considering demand is higher in the summer, he said the shortage could spread to other stations too.

"During the summer when it's high demand, it's never a good time to have a refinery go down," he said.
