The Calgary Police Service closed sections of 6 Avenue Southwest and 1 Street Southwest to traffic and restricted pedestrian access to sidewalks in the area after a window shattered on the 51st floor a downtown high rise at approximately 11:30 a.m.

Emergency crews responded to the yet-to-be opened Brookfield Place building late Sunday morning after window washing apparatus damaged a window near the top of the building.

“The window washers were up their doing some washing when the basket slammed into the glass as a wind gust came up,” said Calgary Fire Department District Chief Frank Ostrow. “They were able to do a self-rescue.”

Ostrow says representatives from Ellis-Don, the construction company in charge of the building, responded to the building and plans are underway to seal the window.

The roads remained closed to traffic into Sunday evening.
