Two Calgary business owners are tallying their losses after a fire ripped through their trucking and trailer repair shop in the Foothills Industrial Park early Thursday morning.

Calgary fire crews responded to the call at around 3:40 a.m. They arrived to find a building in the 5900 block of 94th Avenue S.E. engulfed by flames.

"I'm shocked, I'm totally shocked," said Frontier Inc. co-owner Wendy Pixley.

Still wearing her pyjamas, Pixley watched nervously this morning as firefighters tried to save her family business.

"It's a trailer repair shop and we have a trucking company, and we run trucks all the time," she said.

By mid-morning it became clear the building and all the trucks inside it were destroyed.

Marvin Pixley, Wendy's husband, created the company 15 years ago.

He left the shop last night at 6 p.m. and came back this morning after getting a call about the fire.

"I thought, ‘Oh God, I don't need this’," he said.

"We have insurance, somewhat" he said. "I haven’t had to look at it for many years, so hopefully it's good."

As firefighters put out hotspots during the morning, Pixley called his employees to tell them not to come to work.

No one was injured and the fire department is investigating the cause.
