Three Hamilton area men are among 18 people who have been charged in a year-long guns and gangs investigation. York Regional Police revealed more details Friday of the investigation dubbed “Project Tugboat.”

In the last week police executed 18 search warrants. From these searches they seized five handguns, four assault riffles, and one long gun. They have also seized 8.5 pounds of opium worth $225,000, 13 kilograms of cocaine worth $520,000, along with $76,000 in cash.

So far, two men from Hamilton have been charged — one with possession of a prohibited weapon and careless storage, the other with possession of a controlled substance with purposes of trafficking.

A man from Ancaster has been charged with possession with the purpose of trafficking, and conspiracy to commit an indictable offense.

The investigation continues, police say.

Ontario Provincial Police, along with police forces in Durham, Toronto and Hamilton, and the Canada Border Services Agency have been involved in the investigation.
