It's a great question. We refer to it as the problem of “destining”. Where is the destination for the refugee? There's a different approach in Canada for government-assisted refugees than there is for sponsored refugees. Government-assisted refugees are generally destined to whatever city where they have indicated there's a family tie or any other tie—a friend or some other connection.
Sponsorship is a little more challenging because you obviously need to be destined to the city where your sponsorship group is located. That does create a tension for some newcomers, who are desperate, of course, for a new opportunity to get out of a terrible situation. If the sponsorship group is not in the same location as their family member, that can create a tension.
In Canada, there is a policy not to destine, not to match the UNHCR-referred refugee to a sponsorship group away from the family members, recognizing that tension, but where it's a named case, it's really beyond the control of the policy-making branch. It sits with the sponsorship group and the newcomers to try to triangulate that tension.
