Paramountcy (Canada)
In Canadian constitutional law, the doctrine of paramountcy (French: prépondérance fédérale) establishes that where there is a conflict between valid provincial and federal laws, the federal law will prevail and the provincial law will be inoperative to the extent that it conflicts with the federal law. Unlike interjurisdictional immunity, which is concerned with the scope of the federal power, paramountcy deals with the way in which that power is exercised.
