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.

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.

In a separate interview on CBC News Network later Thursday, he called the incident a mass shooting, and said the scene was "horrific."

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

"I think that's what's most heartbreaking to me and to my family and to all Ottawa residents, is to hear of violence on this scale and to know that children were victims ... it's just really incomprehensible and unimaginable and absolutely devastating."

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.
