We haven't done a lot of work on a bond. As I said, we think that the current process provides a fairly good response to the demand for access to Canada.
Our initial assessment of a bond is that it's fairly administratively challenging to administer. What we've seen in terms of previous experience is that it hasn't really acted as a deterrent in a number of cases where bonds have been used by other countries. People still go underground or forfeit the bond, simply for the opportunity to gain access to another country. The handling of monies, getting into that sort of degree of complexity, adds to our risk in terms of the handling of public monies and that sort of thing.
From our early assessment, it doesn't look like a particularly viable approach, and it was in fact studied by this committee in 2005 and rejected as a recommendation.
