I'll start and Les can jump in if I start to say something that's silly.
Government-sponsored refugees are referred to us by the United Nations High Commission for Refugees as those people who meet the definition of a refugee and who are in need of resettlement. Some folks meet the definition but reside in a stable environment, so those cases aren't referred to us. We process applications for government-assisted refugees, or GARs, as we call them.
Privately sponsored refugees can be any number of things. We have sponsorship agreement folders from NGOs, or church groups and the like, who have formal agreements with the department to bring in privately sponsored refugees under the auspices of the agreement they have with us. Also, groups of five Canadians can come together and choose to sponsor someone and show that they have the wherewithal to look after that privately sponsored refugee on arrival.
Those are the two main processing streams for the overseas context.
