In our federal state, the federal government takes responsibility for matters of national and international concern. These include defence, foreign policy, interprovincial trade and communications, currency, navigation, criminal law and citizenship. The provinces are responsible for municipal government, education, health, natural resources, property and civil rights, and highways. The federal government and the provinces share jurisdiction over agriculture and immigration. Federalism allows different provinces to adopt policies tailored to their own populations, and gives provinces the flexibility to experiment with new ideas and policies.
