Canada and the United States are to start sharing fingerprints, names, photos, birthdays and nationalities of people applying for visas from next year. The name, date of birth and gender details will be shared automatically in 2013 and by 2014 other biometric details such as photos and fingerprints will be added to the system.
This is a result of a new Sharing Agreement signed by US Ambassador to Canada David Jacobson and the Canadian Minister of Citizenship, Immigration and Multiculturalism Jason Kenney. It enables Canada and the United States to share information from third country nationals who apply for a visa or permit to travel to either country.
