The US Homeland Security Secretary suggests there are “instances” when suspected terrorists have attempted to enter the United States from Canada.

In a statement, Janet Napolitano said “some of these are well-known to the public such as the Millennium Bomber, while others are not due to security reasons.”

Napolitano issued the statement to reassure Canadians she knows that no 9-11 terrorists entered the US through Canada.

Napolitano said earlier this week on the CBC that terrorists routinely enter the US through Canada, including the perpetrators of the September 11th attacks.

America’s 9-11 commission concluded in the 2004 that none of those terrorists made it into the US through Canada.



New rules requiring passports or new high-tech documents to cross the United States’ northern and southern borders are taking effect Monday, as some rue the tightening of security and others hail it as long overdue.

The rules are being implemented nearly eight years after the Sept. 11 attacks and long after the 9/11 Commission recommended the changes. They were delayed by complaints from state officials who worried the restrictions would hinder the flow of people and commerce and affect border towns dependent on international crossings.

In 2001 a driver’s license and an oral declaration of citizenship were enough to cross the Canadian and Mexican borders; Monday’s changes are the last step in a gradual ratcheting up of the rules. Now thousands of Americans are preparing by applying for passports or obtaining special driver’s licenses that can also be used to cross the border.
