Canada’s spy agency says its network of informants has been “imperilled” by a Federal Court of Appeal decision that struck down its right to always shield the names of its sources. Public Safety Minister Vic Toews has asked the Supreme Court to overturn the ruling. “As with police informers, the identity of informers who provide information to the Canadian Security Intelligence Service (CSIS) must be protected or their lives and the lives of their families could be at risk,” federal lawyer David Tyndale argues in documents filed in support of the government’s leave to appeal. “Without a guarantee of confidentiality, individuals would be reluctant to come forward and assist CSIS, and sources would dry up.” The appeal court ruling, he says, damages Canada’s national security, impairs its ability to deport foreign-born terror suspects, and creates two classes of informants: those who work for the police and those who work for CSIS. “These are issues of the utmost public importance,” Tyndale contends. In April, the Federal Court of Appeal struck down a blanket legal protection — it’s known as a “class privilege” — that had been extended to CSIS informants. Confidential police sources already enjoy a near-absolute right to have their names kept out of court proceedings. (The lone exception involves a crime in which a defendant’s innocence can only be established by unmasking the informant.) The appeal court, however, said it was unnecessary for CSIS informants to be offered the same automatic protection since other legal safeguards are available to them. The issue first arose in 2008 during Mohamed Harkat’s security certificate hearing.
