Well, I think it's a simple measure in the sense that it's a benefit to the country to make sure that inadmissible people don't get into the country. It's a tremendous benefit to people who are travelling to know that they can enter once they've been pre-cleared abroad. In that sense it's a simple solution to what has been a tremendous problem for the travelling public, particularly after 9/11, when all countries are more stringent about who they let in and who they don't.
Sometimes it's very time consuming and difficult to apply for a visa—you have to go in; you may have to be interviewed. A lot of countries require visitor visas. The only ones that are exempt in Canada are western European countries, or mainly most of the European countries and the United States. Most of the other countries require visas.
