Final answer:
Criminal law in Canada is under federal jurisdiction, and both provincial and federal courts can hear criminal cases. International law consists of rules governing the behavior of nations in their interactions with each other.
Step-by-step explanation:
Criminal law in Canada is the responsibility of the federal government, not provincial, municipal, or international. The authority to enact criminal law and establish procedures for the enforcement of criminal law comes from the national level. In contrast, civil law can involve both provincial and federal jurisdictions, depending on the matter. Crimes in Canada are categorized as either felonies or misdemeanors based on the nature and seriousness of the offense. It is the government that charges an individual with a crime and prosecutes the case in court.
Regarding international law, it refers to a set of formal and informal rules that loosely govern interactions between states and other entities with international legal standing. It's not the law of any single country but a system of rules accepted as binding between nations. International law is inherently more complex due to the anarchic nature of the international system, which can impact predictability at various levels, including the state level.
