The OPP continues its investigation into some illegal dumping of waste in Caledon, and they've figured out where it came from.
There have been numerous reports of garbage bags emitting a strong chemical odour along Boston Mills Road and Mountainview Road.
They believe it came from a drug lab.
The waste is extremely hazardous, and measures were taken to secure the areas where it was found and remove it.
OPP are very concerned with public safety if there is any more of this waste out there, and warn parents to tell their children not to go near or touch any of these products.
