If by complete power you mean the power to do....I believe they have the power right now. They simply will have a fiscal penalty if they choose to exercise it, and that's exactly why we feel this is a completely jurisdictional issue.
Many other folks have made excellent arguments in favour of not introducing a minimum residency requirement. We take no position at all on that issue. We think if that argument is so powerful, it will also resonate in the provincial capitals and this will effectively lead to no change whatsoever on refugee claimants.
