I don't know if we want to establish a separate stream or not. I think that the first person was arguing for a global stream, and we're moving that way with our global case management system, which will be a big improvement for Canada's capacity to deal with people fairly around the world.
In terms of age at immigration, it's reasonably well established in the research literature that there is an important relationship between age at arrival and long-term labour market outcomes. On average, younger immigrants do much better and find it easier to integrate socially and economically into Canada. We want to be thinking about that quite a lot in terms of the delays that we're imposing on people in the backlog.
For parents and grandparents, it depends on whether or not they actually intend to enter the Canadian labour force. One of the things that was suggested earlier for people not interested in entering the labour force is long-term multiple admission visas. Perhaps that's an alternative we might want to think about for that particular subset of individuals.
