Grow op uncovered by Caledon blaze

A huge fire in Caledon has revealed a marijuana grow op.

The fire started in a home on Humber Station Road around six last night, with flames were shooting through the roof.

Tankers were called in because the fire was in a rural area. Several propane tanks exploded but no one was hurt. Damage is set at about $400,000.

There’s no word yet how much marijuana was discovered.
