6 dead including 4 children in Ottawa mass killing

This is the best summary I could come up with:

Six people — four children and two adults — were killed in what Ottawa's police chief called a mass shooting inside a townhouse in the suburb of Barrhaven late Wednesday night.

A male, who police also haven't identified, was arrested at the scene about 15 kilometres south of Ottawa's downtown core.

In an interview with CBC Radio's Ottawa Morning, police Chief Eric Stubbs said the force can't yet comment about the relationship, if any, between the victims and the suspect.

Nepean MPP Lisa MacLeod, whose riding includes this part of Barrhaven, said the community woke up to shock and grief.

On social media, Ottawa Mayor Mark Sutcliffe called it "one of the most shocking incidents of violence in our city's history."

Wilson Lo, who represents the area, said on social media that he was "saddened to learn of the tragic loss of six Barrhaven neighbours," and that his thoughts are with their loved ones and people close by.
