Labertucci said investigators confirmed this fact during the search of the youth home by adding a potentially explosive substance that was removed from home and blew up on Friday morning.
"There were elements and trace elements, but I'm not ready to talk about it in the ongoing investigation," Lambertchi said.
The RCMP said a second man, an elderly man, was arrested but not accused.
The man is Husam One Alzahabi, 20, according to his father, Amin Aljahabi, who said he was not sure what was going on.
"I want to know where she is," Amen Alzahabi told the Canadian press on Thursday at his home in Kingston.
He said he did not talk to his son and did not know where he was.
Amen Alzahabi told the star on Friday afternoon that the police are in his home and that they "want to talk to us about Husam."
The family came to Canada about two years ago after escaping the war-torn Damascus for Kuwait. Their home in Syria is destroyed. The father was once closed because he did not join the ruling political party and would be vulnerable to arrest and heavy revenge if he and his family returned home, according to one of the churches that sponsored the refugee family.
Bronek Korcinsky, who co-chaired the church committee behind the sponsorship, said he and other members of the four churches that had brought the family to Canada were shocked by the news of the younger Alshawby's arrest.
"Although our sponsorship ended last July, many of us in the group maintained a relationship with the family – meaningful relationships – and that's just a real blow to the body," he said. "We are simply puzzled by this. It's so impossible with the family we've met and cared for. "
Korkinsky said he was in a meeting with Kingston and RCMP police on Friday morning, along with other community leaders. The police wanted to ensure that the leaders had the necessary responses and could continue to provide services to the family and the wider community.
"It was a very great opportunity to say," What can the community do to make sure that this does not turn into an incident unjustifiably addressed to any ethnic group, national group, religious group? ", He said.
He added that Alzahabi has a younger and older brother, both of whom are devoted to their education.
One of the possibilities not to charge the second person may be that he cooperates or potentially will cooperate with the ongoing investigation, said Camran Bokhari, a specialist in national security and foreign policy at the Institute for Professional Development at the University of Ottawa.
The police "does not want to burn this individual in the sense that he wants to be able to use his insights into the broader plan," Bokari told The Star. – This is crucial.
"And, of course, they may not be sure," he said. – They can still get more information.
No other country was involved in the alleged conspiracy, and the FBI did not tell RCMP about any relationship with the US, Lambertchi said.
RCMP said there had been an evacuation at a Kingston residence on Friday morning, including bombs that were blown up by the Kingston bomb squad.
Diane Smith-Merrill, who lives on the other side of the street in one of Kingston's homes, told the star that he heard sounds from a small explosion nearby early on Friday morning.
"I took pictures of the bed," she said.
Christian Mate, a student at the Royal University, was sitting inside the house on the other side of the street with a roommate on Thursday when "we saw the lights glow and there were about 30 cops in the street.
Matt said the attack took place about 16 hours. and there was "an airplane flying overnight in the last few days."
"It's usually quite quiet here," Matt said.
At a press conference Friday, Lambertuchi confirmed that the plane was part of the investigation and identified it as a RCMP-managed PC-12 turbine pilot.
"Used for any resource purpose. In this case, I can say that it has been used to preserve public safety and risk reduction strategies in Kingston, "he said.
The RCMP said that both young men and unmanaged men are Kingston residents and are friends. Both were involved in the investigation and were arrested for the same possible reasons, Lambertchi said.
FBI, Kingston Police, OPP, Canadian Border Services, Canadian Intelligence Service, and Canadian Financial Analysis and Reporting Center have been involved. The RCMP said about 300 people participated in the investigation.
Asked if this is a conspiracy for a "lone wolf," or if the accused has had links with a larger group, Public Security Minister Ralph Goudale refuses to go into the details of the case.
"At this stage, the investigation is just starting. From this morning, a set of charges was made, "said Goodal to reporters at Edmonton.
"The process is too early to speculate," Guadale added. "But the police and the security services are very clear that the situation has been neutralized and under control, and Canadians can be confident in Kingston and elsewhere in the country that they are really safe and safe."
There is no change in the level of Canada's threat, Guddle said in a statement sent by email to the star on Thursday.
Federal Conservative leader Andrew Sheer said this incident highlights the "critical importance" of having strong anti-terror laws and appropriate punishments for those who are found guilty of violating them.
"It is also clear that the refugee review process in Canada needs to be seriously explored," said Sheer. "We recently learned of some examples of dangerous people entering the country due to partial weakening of verification procedures."
