Investigators from Niagara Regional Police, Peel, and the Hamilton-Niagara Detachment of the RCMP, started the investigation in the fall of 2021.
Officials say the investigation wrapped up a few weeks ago, and involved 12 search warrants, 175 police officers, and immigration officers.
Several people have been arrested, 120 charges laid, and police seized a large quantity of coke and cannabis.
The NRP will release more details on the operation on Thursday.
