I think temporary foreign workers are in a more precarious situation. Their vulnerability is acknowledged by the employers and by the labour contractors who bring them here. If you come here as a permanent resident, you know you have certainty and cannot be deported because of an employer's whim. So I think the abuse of temporary foreign workers will continue, because workers are very much in a precarious situation and they're very unlikely to complain about the situation they're in.
