OTTAWA - Three days after the February mass shooting in Tumbler Ridge, B.C., government officials warned Prime Minister Mark Carney that online sentiment was shifting from collective grief toward “emerging accountability narratives” — including questions about mental health intervention, firearms access and whether warning signs were missed.

The memo to Carney from the Privy Council Office said the overall public reaction was dominated by a sense of shock and national mourning, with strong expressions of solidarity and support for victims, families and the devastated northeastern British Columbia community.
