The federal government has responsibility for the borders of Canada, and that's a fundamental federal role constitutionally. In the current immigration act, none of the provinces has authority to deal with what we call admissibility processes relating to the health and safety of Canadians and security and criminality. It would be a very profound change if we were to begin to introduce varying provincial responsibilities in that regard, given internal mobility.
Any person admitted to the country is admitted to the country. So if you're looking at local labour market needs, I think it makes a lot of sense for the provinces to have a very significant role in selecting persons to integrate into their local labour markets. But when we're talking about the health and security of Canadians, having 13 jurisdictions with roles there might be a recipe for considerable difficulty.
The Auditor General pointed out the challenges of the current system in ensuring good communications between differing government departments responsible for screening of immigrants and visitors, so that would be a very significant constitutional and legal change.
