BEETON, Ont. — Provincial police say a fire about 75 kilometres north of Toronto led officers to a "clandestine" drug lab.
They say the fire occurred on May 15, 2016, at a home just outside of Beeton, Ont.
Investigators say they recovered approximately 26.5 kilograms of ketamine in various stages of refinement from the home.
OPP say two Toronto men — aged 45 and 52 — were arrested on Tuesday, and warrants are outstanding for a 40-year-old woman and a 46-year-old man.
All are charged with possession of a controlled substance and possession for the purpose of trafficking.
