I'm not aware of any studies like that. I could definitely do some research and remit it to the committee, if that would be helpful.
Just from my own perception in doing a lot of this work, at least when it comes to privately sponsored refugees and self-supporting refugees, there's probably an unlimited capacity for absorption, because these people are not taking any resources. They're financially supported by external agencies for at least the first year they're here. So there's absolutely no reason not to increase those quotas.
