Ottawa (CNN)Christianne Boudreau's voice wavers slightly as she recounts how her little boy became an ISIS militant. Every word seems tinged with anger and regret, but most of all, purpose. The process of radicalization is gradual and persuasive, she said. And deadly. Her son, who joined ISIS's ranks in Syria, was killed in fighting there more than a year ago. "It's so easy for them to get to our children, to access our children," she said. Boudreau's son, Damian Clairmont, converted to Islam after a troubling period in high school in Calgary, Canada. The mother remembers her son's religion bringing him peace. She didn't suspect anything when Clairmont told her he was leaving for Egypt to study Arabic.

But that changed when @placeholder moved out on his own, changed mosques and sought out more and more radical content online, his mother said.

What @placeholder learned is while youths can become radicalized online, there is nothing to counter it or to provoke questions about what they are being told.

@placeholder wishes the Canadian government had the power then to do what it is doing now: Confiscate passports of Canadians suspected of communicating with terrorists.
