Authorities arrested a 23-year-old man in the Toronto suburbs on a terrorism-related charge, but stressed it was not linked to the deadly suicide bombings in Brussels.
Kevin Omar Mohamed was arrested under a "Fear of Terrorism Offence" law, the Royal Canadian Mounted Police said in a statement, suggesting he was preparing to travel abroad to train with extremists.
He was also charged with carrying a concealed weapon and possession of a weapon dangerous to public peace. If convicted, he could face a maximum of 10 years in prison.
"While there was no indication of any plans for a domestic attack, we must remain committed to preventing individuals from traveling abroad to gain training and expertise that could be used in the planning and implementation of future attacks on Canadian soil," Superintendent Lise Crouch was quoted as saying in the statement.
Mohamed was scheduled to be indicted on Tuesday at a court in Brampton, a suburb west of Toronto, Canadian police said.
Around sixty Canadians who traveled abroad to join terror groups are now back in the country, and another 180 are estimated to be overseas engaged with extremists, Canada's spy chief Michel Coulombe told a newspaper last month.
