A massive blaze broke out at an industrial plaza in the city's east end Thursday morning.

Ottawa Fire were called to 5370 Canotek Rd. around 1:30 a.m.

When crews arrived, they confirmed the fire started in an auto detailing buinsess in a multi-unit commercial structure.

The fire was under control just before 2:00 a.m., but it had spread to six other businesses in the plaza. 

Ottawa Police, Paramedics, Enbridge Gas, and Ottawa Hydro all responded to the blaze.

The damages to the businesses have been pegged at $400,000.

The cause has yet to be determined.

More to come.
