Normally, before a refugee is resettled, we try to get the family together and then resettle the entire family. If that is not possible and the situation is urgent, then the family members who are refugees somewhere are resettled, and then we try later on to reunite the family, but that often takes time.
Canada, of course, does a lot of this. Many of the refugees resettled, including the Syrians resettled over the last year, now have family members coming out of Syria—because normally they're still in the country of origin—by means of family coming to Canada. This would also apply once Yazidi refugees have been resettled to Canada if the remaining family members are still in northern Iraq.
