An 18-year old man has been formally charged after a scary discovery this holiday weekend at a north end Cartierville home.
19 explosive devices were discovered at a triplex on Robertine-Barry street, all eventually dismantled.
Firearms were also seized.
He's identified as Jordi Antunes-Barros, who faces four different charges.
They're said to be possession of incendiary material, possession of a weapon for dangerous purpose, using explosives and possession without lawful excuse.
He remains in police custody and is expected to undergo a psychiatric evaluation.
The suspect has another court appearance scheduled for Tuesday.
Some 50 area residents were forced out for a time during the hours-long police operation, which began Saturday.
