At this point it's not possible to have accurate statistics because we don't have systematic entry and exit information systems, although under the beyond the border action plan with the United States, there's a pilot project that has already been undertaken at the land border by CBSA to start capturing that information. We will be moving to more systematic capture of entry and exit information on foreign nationals over the course of 2013.
The Border Services Agency is leading that initiative. From CIC's perspective we're interested in seeing that being expanded into the air mode as quickly as possible, so that we can then have more reliable information on who's in the country and for how long. If and when they do choose to leave, we and CBSA will have a better idea as to what the actual overstay population is.
