The theatre was being built with seven traditional movie screens, three VIP screens, and one Ultra AVX screen, according to the Seton urban district website.

Stephane Heroux, a subcontractor working on the project, drove to Seton after hearing about the fire.

“I got a few texts, a few phone calls, saying ‘guess what? Your project is on fire.’”

The stand-alone building was scheduled to open within weeks.

Heroux said it looked as though it was one of the three VIP screens that may have sustained most of the damage.

In a statement, Sarah Van Lange from Cineplex Odeon said they are in the process of assessing the damage caused and are unsure when the theatre will open.

“We would like to express our heartfelt appreciation to the local fire department and the Calgary police for their support on the scene and are so grateful that no one was injured.”

The cause of the fire is under investigation.

On Monday morning, Carol Henke with the CFD said fire crews had not yet been able to enter the area of the theatre where it’s believed the fire started.

“The wall is sort of leaning and so it’s not currently safe to go in.”
