St. Catherines’ acting fire chief says there will be no investigation into the cause of a large greenhouse fire at Pioneer Flower Farms due to ‘extensive damage.’

Jeff McCormick revealed in a media release on Tuesday that the Ontario Fire Marshal’s office will not be conducting a probe because of the “extensive damage to the 700,000-square-foot structure.”

“Due to numerous factors including the size and scope of the fire, the length of time the fire burned and the extensive overhaul operations that were necessary to ensure final extinguishment, there is no reasonable expectation that they would be able to determine the cause and origin,” said McCormick.

That means the cause of the fire will be left “undetermined,” according to the chief.

Firefighters from St. Catharines, Thorold, Niagara-on-the-Lake, Pelham, and Lincoln battled the fire after receiving a call around 11 p.m. Friday night to Pioneer Flower Farms just off of Seventh Street and Highway 77.

McCormick said more than 27 vehicles and 100 firefighters were a part of the effort, with the fire finally doused at about 4 p.m. on Monday afternoon.

The fire originally started in one of the greenhouses on the east side of the site, eventually spreading across the grass and into a bush that caused a significant bush fire.
