The teenage suspect in a mass shooting in rural British Columbia had been the subject of a number of police visits in recent years because of mental health issues, authorities say.
Police say the 18-year-old - who was found dead on the scene from a self-inflicted gunshot wound - killed eight people, including six children, in Tuesday's attack in Tumbler Ridge.
Jesse Van Rootselaar had previously been apprehended and assessed under the Mental Health Act, and used to have a firearms licence.
It is unclear who owned the guns used in the attack, or what was the motive. Prime Minister Mark Carney has said he will visit the mountain town in the coming days.
British Columbia, in western Canada, proclaimed Thursday a day of mourning across the province.
Five students aged 12 to 13 and a 39-year-old teacher were killed and at least 25 others were injured at Tumbler Ridge Secondary School.
Two others - the suspect's mother, also 39, and 11-year-old step-brother - were found dead at a nearby home, where the attack began.
In Tumbler Ridge, flags remained at half-mast on Thursday, and a memorial to the victims was growing as mourners stopped by to drop off teddy bears and flowers.
"Small towns are small towns. We look out for each other. It's not like living in a city where you don't know your neighbor," said Shelley Quist.
The Royal Canadian Mounted Police (RCMP) had reported a history of interacting with Van Rootselaar's family over the past several years linked to the suspect's mental health challenges.
Authorities found two firearms - a long gun and a modified handgun - at the scene of the incident, but they are still investigating how the suspect obtained the weapons.
The community continues to grieve, reflecting on the profound impact of this tragic event.
