Provincial police seized nearly 300 kilograms of cocaine with a street value of roughly $29 million following search warrants in the Greater Toronto Area (GTA) and Gravenhurst.
Ontario Provincial Police (OPP) also say that five accused face 12 charges.
"The Ontario Provincial Police (OPP) Provincial Guns and Gangs Enforcement Team (PGNG) initiated Project SHEARWATER in September 2024 after investigators became aware of high-level drug trafficking activity," OPP stated in a release.
"This five-month intelligence-led investigation focused on a cocaine trafficking network spanning throughout the GTA."
The OPP Provincial Weapons Enforcement Unit (PWEU), Organized Crime Task Force (OCTF), OPP Central Region Community Street Crime Units (CSCU), Toronto Police Service (TPS), and York Regional Police (YRP) assisted.
"On December 13, 2024, PGNG executed a search warrant on a residence and vehicle in Mississauga," OPP said.
"Between January 16 and 17, 2025, the OPP-led PGNG, OPP PWEU, OPP CSCU, OCTF, as well as TPS Emergency Task Force and Durham Regional Police Service, executed five search warrants in Toronto, Ajax, Markham and Gravenhurst, and five search warrants on vehicles."
Throughout the investigation, police seized 299 kilograms of cocaine with an estimated street value of $29 million, and over $50,000 in Canadian currency.
Police say four of the accused have been arrested and charged with 11 offences, while the fifth accused is a Mexican national who was subject to an immigration warrant for removal issued by the Canada Border Services Agency.
An arrest warrant has been issued for the fifth suspect.
The accused are from the Greater Toronto Area and London, according to police.
Two of the suspects remain in custody.
