The Toronto Police Service is making the public aware of an arrest made in a firearm manufacturing and trafficking investigation involving privately manufactured firearms.

On December 9, 2025, Brian Narciso, 28, was arrested and charged with multiple offences related to firearm manufacturing, trafficking, and unauthorized firearm possession. The charges include a new offence under Canadian law: possession of computer data for the purpose of manufacturing or trafficking firearms, contrary to section 102.1 of the Criminal Code.

This investigation highlights the emerging issue of privately manufactured firearms, sometimes referred to as “ghost guns.” While individual firearm parts may be legally acquired, the private manufacturing of key components can result in fully functioning firearms that are untraceable and fall outside traditional regulatory controls.

The success of this investigation is the result of the work of the Toronto Police Service’s Firearms Enforcement Unit (FEU), with support from the FEU Integrated Criminal Intelligence Analyst, the Firearm Investigative Analysis Unit (FIAU), as well as the Chief Firearms Office. Investigators also worked in collaboration with the Royal Canadian Mounted Police (RCMP), and the Ministry of the Attorney General – Guns and Gangs Unit.

Project CLUSTER

In November 2025, the Toronto Police Service’s Firearms Enforcement Unit (FEU) was alerted by the RCMP to several suspicious online advertisements posted on a firearms website.

Investigators determined that the firearm parts and components being sold were consistent with those used to assemble functional firearms.

As a result, the FEU launched Project CLUSTER, a firearm manufacturing and trafficking investigation.

Through the investigation, the individual alleged to be responsible for the advertisements was identified as Brian Narciso. Investigators developed a comprehensive investigative plan, supported by consultation with the Ministry of the Attorney General – Guns and Gangs Unit.

During the investigation, it is alleged the accused sold a 3D-printed handgun receiver — the core component that legally defines a firearm under the Criminal Code of Canada — along with additional parts needed to complete it.

Search Warrants and Seizures

On December 9, 2025, Criminal Code search warrants were executed at Narciso’s residence and in associated vehicles.

Investigators seized completed firearms, including 3D-printed handguns, along with components capable of assembling 24 prohibited firearms. They also recovered digital evidence from computer systems and electronic storage media, as well as a 3D printer, mobile devices, and proceeds obtained by crime.

Connection to Firearm Discharges

Between June 28, 2025 and October 29, 2025, six firearm discharge incidents were reported in the Lawrence Avenue West and Caledonia Road area of Toronto.

It is alleged that Narciso attended a secluded area and discharged firearms on multiple occasions. Over 100 cartridge casings and unspent rounds were recovered, and on one occasion, a projectile entered a nearby residence.

Forensic analysis using the Integrated Ballistics Identification System (IBIS) linked multiple incidents to the same firearm.

Further examination determined that two 9mm 3D-printed handguns seized during the investigation were forensically linked to the three discharge incidents that took place in October 2025.

Brian Narciso, 28, of Toronto, is charged with, Firearm Trafficking, Possession of Data for Purpose of Manufacturing a Firearm, Four counts of Manufacturing Prohibited Firearm, Possession of a Firearm for Purpose of Trafficking, Two counts of Possession of Firearm Parts for Purpose of Trafficking, Two counts of Possession of Proceeds of Crime Exceeding $5000, Three counts of Possession of a Prohibited Device, Two counts of Possession of Loaded Firearm, Two counts of Possession of Firearm with Readily Accessible Ammunition, Reckless Discharge of a Firearm, Reckless Discharge of a Firearm Endangering Life. 

He appeared in court at the Ontario Court of Justice, 10 Armoury Street, on February 26.
