The parents, who spoke on the condition of anonymity in fear for their other children, sobbed during an interview with Radio-Canada.
"My son is now in a butcher shop," the father said. "We do not eat, we do not sleep … our lives have plunged into horror."
Their son, who recently turned 18 years old, flew from Pierre Elliott Trudeau airport in Montreal to Istanbul.
He was one of six Quebecers who left the province earlier this year.
That group includes two women and four men. Of those six, four of them attended Collège de Maisonneuve in Montreal’s east end.
When the teenager’s mother found out her son had left the country, she said she collapsed.
"I thought to myself, this cannot be," she said.
The parents describe their son as polite, smart, curious and naive. They say he loved helping other people.
The family are practising Muslims, hailing from northwestern Africa, but don’t attend mosque regularly. The teenager’s mother said she often reminded her son to pray at home.
Son attended Collège de Maisonneuve
Until September, he was a practising Muslim, but not especially devout. However, he started CEGEP at Collège de Maisonneuve College last fall. That’s when he told his father he wanted to take courses in Arabic to learn more about his religion.
He took classes with Adil Charkaoui, the leader of the east-end Islamic community centre.
Soon after, the teenager started growing a beard, which concerned his father.
"I don’t want to stigmatize men with beards, but my son had a beard because of his religious convictions. That’s what made me think something was up."
He hid his son’s passport, but his mother was less worried.
"My son showed no signs, in conversations at home.… He spoke, ate with us, and laughed with his brothers."
The father forbade his son to attend classes with Charkaoui, and asked him to cut his beard. His son obeyed, but in hindsight, his parents believe it was too late.
They would later learn he applied for a new passport, which he received in late December.
Parents blame themselves
"I feel like I’m responsible," said the father through tears.
The mother said she wanted to send a message to her son.
"Come back," she said, "Because I miss you a lot."
"I want him back, I don’t want to lose him. I still have hope … maybe it’s a nightmare and I’ll wake up."
The parents spoke to Radio-Canada hoping that other parents will learn from their experiences.
The father said the solution to radicalization of youth must involve religious leaders condemning acts of violence.
