Killed his family and then went on a further rampage? https://twitter.com/CBCAlerts/status/1251982200985223176
First report I've seen mention (a whole 24 paragraphs into the article) that he has or had a common law partner, who is a woman. https://www.thechronicleherald.ca/news/local/those-who-knew-gabriel-wortman-stunned-by-news-of-shooting-spree-439461/?utm_medium=Social&utm_source=Facebook&fbclid=IwAR1bxZfDKbmU0BNQ9736Vf0X0VuMk_rTrHqjTr6nt2zwYo7IR7csf4BPx0o#Echobox=1587337626
Mentions he had "issues with his relationship", that the way he treated his girlfriend was "a red flag" and that his violent rampage "wasn't a surprise to some degree". Described as having an "obsession with his girlfriend".

From @CAN_Femicide's 2019 report, some of the gender-related motives and indicators of femincide.
Obviously I hope to be wrong about this. In the case that I'm right, however, it will be just one more example of media erasing the gendered dimension of this kind of violence https://twitter.com/degendering/status/1252052407208620040
Toronto Sun reports that he killed his ex wife and her new boyfriend. https://torontosun.com/news/national/hunter-gunmans-pals-didnt-see-nova-scotia-massacre-coming
Politicians and media will line up one by one to tell you "we may never know the motive behind this senseless violence". But it's not "senseless" or "unknown"; it's known all too well but unacknowledged, obfuscated, to avoid calling men's violence what it is. #CallitFemicide
Senseless violence... No idea what caused it 
"Wortman escalated the argument [w/ his girlfriend] — assaulting her and tying her up. She escaped and hid... investigators believe that’s when the shootings started" https://twitter.com/CAN_Femicide/status/1253423056539627533?s=20
