It may be little more than a token measure, but the Canadian government is moving to revoke the passports of Canadians known to have gone overseas to join ISIS:
AS WESTERN democracies struggle with how to deal with homegrown terrorists fighting abroad, the Conservative government of Canada has begun revoking the passports of its foreign fighters as well as people still in Canada planning to join them. Chris Alexander, minister for citizenship and immigration, would not say exactly how many passports have been revoked, only that it has been done multiple times against some of the estimated 130 Canadians fighting with extremists, dozens of whom are in Iraq and Syria.
Taking passports away from suspected terrorists is controversial. It gives other countries the incentive to respond in kind, and it severs the route home for those who might be having second thoughts. Human-rights advocates in Canada say the secretive process used to determine whether a person is a threat to national security, one of the criteria for having your passport revoked, allows the government to make arbitrary decisions. These can be challenged in court but only within 30 days of the decision.

Ever since the attacks on the United States in 2001, Canada has been toughening its terrorism legislation. In 2004 a Liberal government brought in a law allowing it to revoke passports under certain circumstances. This is the power the government is now using. In 2013 the Conservative government made it a crime to leave or attempt to leave the country for the purpose of committing terrorist acts abroad. Earlier this year the government passed a law allowing it to revoke the citizenship — not just the passport — of dual citizens convicted in Canada or abroad of major crimes, including terrorism. Mr Alexander has not yet used this power but says he will do so, despite objections that this creates two-tiered citizenship.
