The one-year window process is for when you have a refugee nuclear family separated at the time of the application. Let's say, for example, that the wife and children were in Lebanon and the husband was working in a Gulf state or in Europe, for example. That process enables us to process the family to which we which have access immediately, bring them to Canada, given them permanent resident status without examining the other family member and then that application can be submitted during one year for that person to come. The non-nuclear family sponsorship entitlements for refugees are the same as they are for other Canadian permanent residents or citizens. They can sponsor their parents under the family class but Canada does not have a sponsorship program for siblings. That said, a very large proportion of the privately sponsored refugees through sponsorship groups are in response to the requests of refugees to bring in family members.
