In a significant development over the weekend, York Regional Police arrested three individuals after discovering a loaded gun and an assortment of drugs during a traffic stop in Markham. The incident occurred in the vicinity of 14th Avenue and Beckenridge Drive on Saturday. Officers, while on patrol, intercepted a vehicle suspected of transporting cannabis against the regulations of the Cannabis Control Act. Upon inspection, police located a loaded firearm, illicit cannabis, drugs believed to be oxycodone and cocaine, and a sum of cash within the vehicle.

The three occupants were taken into custody. A subsequent search on Sunday at a residence linked to the suspects resulted in the seizure of additional drugs, including cannabis and substances believed to be psilocybin and ketamine. Seliyan Surenthiran, 27, Seyon Surenthiran, 31, and Vijikaran Sivanesan, 40, all from Toronto, face multiple charges, ranging from unauthorized possession of a firearm to several drug-related offenses. Seliyan Surenthiran was already under firearms prohibition orders from prior incidents.
