Well, Mr. Chair, that's a very good question. We have a very comprehensive risk profile that we develop in terms of whether or not a country should have a visa exemption or a visa requirement.
As the committee is aware, the Czech Republic and Mexico before 2009 were visa-exempt. We saw significant influxes of asylum claimants, which resulted in a visa being imposed on those two countries to ensure that the risk to the asylum system was well managed.
So we would do periodic reviews of countries to determine whether or not there were significant infractions of immigration requirements or significant numbers of asylum claims. Based on our review, we would make recommendations to the government on whether or not a visa should or should not be imposed.
