An early morning blaze at a small-town farm led police to the discovery of a multi-million dollar grow-op on Sunday.

The South Simcoe police were called at around 5 a.m. to a barn house in the area of Simcoe Rd. and Canal Rd. in Bradford West Gwillimbury.

Police attempted to wake up the residents at a nearby two-storey home 20 feet away from the barn on the property. After no response, they kicked down the door and discovered the residence filled to the brim with marijuana plants.

"The house was full of it," said Sgt. James Buchanan.

Approximately 2,300 plants were found with an estimated street value of $2.3 million.

The nearby barn was completely burned down, though police say that it was also used to store and grow marijuana plants.

Police have not been able to determine the cause of the fire at this time.

Bradford West Gwillimbury, located 35 kilometres south of Barrie, is a town home to just 28,000.

"Historically there have been large grow-ops over the years in the area. You can stumble on two grow-ops in a week, but not have another one in eight months," said Buchanan.

Two 40-year-old men have been arrested and remain in police custody. Their names are not being released at this time.
