The threat of jet fuel running out at the Yellowknife airport — a threat that raised concerns in the N.W.T. legislature before the weekend — ended Monday morning when one of the airport's fuel suppliers received four tanker trucks of fuel.

Midnight Petroleum's resupply arrived after the Merv Hardie ferry crossing at Fort Providence opened for the season. The company's supply of jet fuel had dipped so low last week that fuel was being rationed and pilots told to fly into Yellowknife with their own fuel cache.

Imperial Oil, which supplies Midnight Petroleum, blamed last week's fuel shortage on the Mackenzie ice crossing at Fort Providence closing a week earlier than expected this year. The fuel was stuck on the other side of the Mackenzie River.

"Like any number of other industries in Yellowknife, we experienced some product tightness because of the premature outage of the ice bridge that links Yellowknife to Fort Providence," Imperial Oil spokesperson Kim Fox said Monday.

Fox declined to say how low Midnight Petroluem's supply fell, or at what level what it is now.

On Friday, Great Slave MLA Bill Braden said a shortage of jet fuel at the local airport could create an urgent situation by the end of the weekend.

Transportation Minister Kevin Menicoche said at the time that if the fuel did not arrive on Monday, planes might have to be diverted to Hay River for refuelling.
