The man who fatally shot his girlfriend and her father on New Year's Eve in Halifax before killing himself was wanted by Toronto police in relation to a nightclub shooting in 2019.

Halifax Regional Police confirmed Friday that Matthew Costain, 39, who is the sole suspect in the double homicide, is the same Matthew Costain with an outstanding arrest warrant in Ontario.

The Toronto Police Service told CBC News Costain was wanted for "several 2019 firearm offences in Toronto."

According to the Toronto Sun, Costain was a suspect in a shooting at a packed nightclub in North York in August 2019. 

Toronto Police said they found five victims at the nightclub, including one male in life-threatening condition and four others, including two females, in non-life-threatening condition.

Offences dating back 20 years

Costain does not have a criminal record in Nova Scotia but he has a lengthy one in Ontario, where he grew up. Two decades ago, he faced armed robbery and firearms charges and was sentenced to two years in jail.

In 2014, he was sentenced to five years and nine months after being found guilty of firearms offences. He was credited for already having served two years on remand.

Reporting by the Fort Erie Times says when Costain was in jail in 2014, he was charged with assaulting three other inmates. 

The Toronto Star has also reported on Costain's history in Ontario, including an excerpt from a sworn affidavit he gave as part of a 2016 lawsuit on solitary confinement.

History of domestic violence

In addition to the charges he has faced, court records provide some other insight into Costain's past.

A 2010 court decision reveals that Costain had a history of physically abusing a past partner.
