Well you just mentioned 25,000, so that clearly includes government-assisted refugees.
In terms of government-assisted refugees, they get income support for one year. The privately sponsored get income support for one year from the private sponsors. After that, government-assisted refugees still, for 39 more months, have access to other settlement services, but not to the income.
You ask what happens. The hope is that after one year they will be sufficiently on their feet to support themselves. From experience with waves of refugees, whether from Vietnam, from Uganda, from Hungary, or from other places, generally speaking those individuals do well in Canada, have found jobs, and have made contributions back to the economy.
It won't be 100%, and if there are some who are still struggling, they'll be in the same situation as other Canadians. They would have recourse to social assistance, as do other Canadians, if they are not in good shape. I think, however, that our historical experience on refugees settling in and doing well has been positive, so I'm confident that a similar pattern will apply in this case.
