The morning commute was a bit longer than usual on Monday as Calgary Transit announced delays of about 20 minutes on all LRT lines. Delays in the city's northeast ran about 30 minutes.

Track switches were not working in various locations because of the cold, but operations had returned to normal by 2:30 p.m., said transit officials.

The cold weather was also slowing flights through Calgary International Airport, said spokeswoman Jody Moseley. She suggested passengers check with their airlines before going to the airport.

Westjet spokeswoman Gillian Bentley said de-icing planes in the extreme cold was delaying about five per cent of its flights in Calgary, Saskatoon, Regina and Halifax.

Snow and blistering winds reaching 60 km/h ushered in the cold snap on Sunday. Environment Canada said an Arctic ridge brought the deep freeze, which is forecast to continue through the week.

The Foothills School Division, south of Calgary, said its schools will be open Tuesday but buses will not be running in town or in rural areas including High River, Okotoks and Black Diamond.

School was cancelled Monday in a few Calgary-area divisions including Golden Hills — which covers public schools in Strathmore and Carseland — and Livingstone Range, which cancelled classes in Pincher Creek, Lundbreck and Crowsnest Pass.

The Calgary Board of Education is asking parents to check with its website for the latest school-bus cancellations and delays. Many drivers had trouble getting their buses started on Monday.

Calgary police are urging motorists not to leave their cars running for any length of time to avoid having them stolen.

Drivers with dead batteries in their vehicles were waiting up to 90 minutes for a boost, some tow truck companies said Monday.

Conditions ideal for frostbite

Stuart Brideaux, spokesman for Calgary EMS, said the frigid temperatures create a real risk for frostbite, which is signalled by localized pain, numbness and blackened skin.

"Frostbite is frozen skin or frozen tissue and you can prevent that by dressing appropriately using gloves and tuques, scarves, neck-warmers, and checking yourself and others periodically when you are out in extended periods of cold weather for signs and symptoms of frostbite before it progresses too rapidly," he said.

Calgary firefighters worked in temperatures of -28 C to put out a tractor fire in the southeast Sunday night. Crews rotated tasks to stay warm, said the fire department. Arson investigators have been called in.

Shelters welcome all

About 1,000 people sought shelter in the Calgary Drop-In Centre on Sunday night but the night supervisor, Tim Gorman, said no one was turned away.

"Certainly around shelters at this time of year and especially around those extremely cold days, there's a sense of nervousness and tension. We certainly don't want anyone to be outside and to freeze outside and so that's all of our fear," said Gorman.

He said the extra spaces provided by the emergency shelter in the Foothills Industrial Park helped prevent a shortage of shelter for the city's homeless people.
