Theoretically, provinces have a great deal of power relative to the federal government, with jurisdiction over many public goods such as health care, education, welfare, and intra-provincial transportation. They receive "transfer payments" from the federal government to pay for these, as well as exacting their own taxes. In practice, however, the federal government can use these transfer payments to influence these provincial areas. For instance, in order to receive healthcare funding under Medicare, provinces must agree to meet certain federal mandates, such as universal access to required medical treatment.
