A fire broke out around 4 a.m. at the Guinois RGR in Sainte-Clotilde-de-Chateauguay, about an hour southwest of Montreal.
The fire is believed to have started when a compressor exploded on the roof of a warehouse.
Temporary foreign workers living behind the structure were not injured and their residences were not affected.  No other injuries were reported.
Sainte-Clotilde-de-Chateauguay fire chief Benoit Tardif said the structure is not safe to enter at this time.
“It’s a great size,” he said.  “Inside the building, you have a basement, so you can’t get in.”
The building was renovated four years ago.
Guinois RGR is a major producer of vegetables sold to major grocery chains, wholesalers and markets in the US.  It has been active since 1893.
