Again, I'm not aware of a specific study.
However, certainly in the process of looking at the refugee reforms that were brought forward in 2012, as a government, we were looking at irregular patterns of migration. There were some countries that seemed to generate a large number of unfounded or abandoned claims. The reforms that were brought in during 2012 looked to address some of the issues, for instance, around the length of time that it took to process an Immigration and Refugee Board process.
A lot of those things were looked at, and as a result there has been a dramatic change in some of those categories. The numbers of claims are down overall, and the acceptance rates are up. We were looking as a government from a policy perspective at some of those considerations around pull factors, as you called them, things that might incentivize some of these unfounded claims. Those were some of the things we looked at.
