A plot by a group of armed people to carry out a shooting spree in Canada's Nova Scotia region on Valentine's Day has been foiled, Canadian police said on Friday. 

A 19-year-old man from Nova Scotia and a 23-year-old woman from Illinois had planned to carry out a mass murder at a public venue in the Halifax region on 14 February, and had also decided to shoot themselves, the Royal Canadian Mounted Police said in a statement.

The man was found dead in a house on Friday, and the police arrested the woman and two others, Reuters reported.

"We believe we have apprehended all known individuals in this matter and eliminated the threat. We are not seeking any further suspects at this time," the police said.

The motive behind the plot to kill multiple civilians on Valentine's Day is still unclear, but the police stopped short of calling the plot a 'terrorist' act.

"I would classify it as a group of individuals that had some beliefs and were willing to carry out violent acts against citizens, but there's nothing in the investigation to classify it as a terrorist attack," Nova Scotia RCMP Commanding Officer Brian Brennan said.
