Police say 45 arrests were made across Canada as part of the investigation
Hundreds of firearms have been seized by police after a cross country search.
The investigation began in Montreal when police received word of a business selling weapon parts.
Charges have been laid across the country, with 11 Ontarians arrested.
Yesterday, OPP conducted 14 search warrants, and found items including (but not limited to) 3D printed firearms, handguns, airsoft rifles, firearm parts, magazines and thousands of rounds of ammunition.
According to the OPP, 3D-printed guns are an especially big concern because they can't be traced.
They also don't have serial numbers.
Local forces participating include Durham Regional Police, Niagara Regional Police and Toronto Police Service.
Search warrants also took place in seven other provinces.
Across the country, 45 arrests were made.
"Canadian police organizations are working together to fight the emerging phenomenon that is 3D firearm manufacturing," said SQ Chief-Inspector Benoit Dubé. "Today's operations will neutralize a number of illegal firearms providers in Canada, and as a result will reduce armed violence in the country."
