A young couple on trial for terrorism-related charges has been found not guilty on most counts.

Sabrine Djermane, 21, and El Mahdi Jamali, 20, were accused of trying to leave Canada to join ISIS, committing an act to profit a terrorist organization, and possession of explosives.

Jurors found Djermane not guilty on all counts, and declared Jamali not guilty of the terrorism-related charges.They found him guilty of possessing an explosive substance.

With that verdict Djermane was immediately freed Tuesday after having been in custody since her arrest in 2015, and had a joyful reunion with her family.

"I'm satisified, very satisfied," she said in the courthouse.

Jamali was released later in the day with his sentence taking into account the time he has already served.

They jury rendered a verdict on its fifth day of deliberations at the Montreal courthouse.

The couple pleaded not guilty to the charges and did not present a defence through the trial as their lawyers argued the prosecution never proved the couple wanted to leave Canada to join ISIS.

"This is the best possible outcome. We worked hard for this. There were tears when I saw her and I do not doubt there are tears of joy," said Djermane's lawyer Charles Benmouyal.

The Crown alleged that the couple wanted to go to Syria to join ISIS and much of the evidence presented at the trial was circumstantial, with the Crown showing notes, emails, Facebook messages and documents showing that Djermane and Jamali had become radicalized and had materials to build a bomb.

The sole guilty conviction was for the possession of explosive materials, but the jury determined that while Jamali had purchased the makings of a bomb, it was not linked to terrorism.

Jamali's lawyer said all the evidence, including propaganda videos on their computers, proved was that the couple was curious about events in Syria and the war involving Islamic State.

"Being curious is not a crime and that was since day one my best argument," said Tiago Murias. "Reading the newspapers about the Islamic State is not a crime."

The Crown also focused on the respective financial situations of the pair -- that they'd both plowed through lines of credit and emptied their bank accounts leading up to their arrest.

There is more evidence the jury did not hear. For example, several friends and relatives of Djermane told police that the young woman had become radicalized not long before her arrest.

Djermane allegedly told friends she was determined to join the jihad, even if it meant going to prison for 15 years.

She also allegedly told an acquaintance that if she couldn’t make it to Syria, she would begin the fight in Canada.

To another relative, she allegedly said it was okay to kill in order to save Muslims.

These allegations were never presented, because the relatives changed their stories after the couple was arrested, and so the Crown never called them to testify.

"The Crown presented the evidence at trial that was admissable, that was available," said Prosecutor Lyne Decarie.

"Evidence sometimes changes."

The couple will have to respect several conditions of a peace bond file against them when they were arrested in 2015, including staying clear of the east end mosque run by Adil Charkaoui.

That peace bond will remain in effect until at least January.

"Obviously if we're continuing with these grounds its because there is reasonable ground to fear the possiblity of offences," said Decarie.

A fourth charge of facilitating a terrorist act was dropped during the trial.

Meanwhile the Crown is considering an appeal of the verdict and has 30 days to file the paperwork.
