Police north of Toronto have arrested and charged one suspect after uncovering a clandestine drug lab.

York Regional Police officers responded to an unknown trouble call on the evening of Monday, December at approximately 9:30 p.m..

Upon arriving at a townhouse residence in the area of 16th Avenue and Bayview Avenue, officers located a man on the premises, and later discovered that the unit was being used as a clandestine lab suspected to be pressing oxycodone pills for illicit consumption.

Police later obtained a search warrant for the property, returning the following day to discover alleged evidence of a drug production lab, including 23 kilograms of various powders, 781 litres of liquids, more than 34,000 pills suspected to be oxycodone and various pill-making paraphernalia.

The combined value of the substances is estimated by police to be north of $1 million.

Investigators also recovered "a number" of rounds of 9mm ammunition, though there have been no reports of a firearm recovered.

Zoltan Mootoo, 35, of Markham — who was already on probation at the time of the seizure — has been charged with a laundry list of criminal offences.

These include possesion of a controlled substance, three counts of possession for the purpose of trafficking, possession of an item to produce a substance, careless storage of ammunition and two counts of fail to comply with a probation order.
