Final answer:
The three layers of human rights protection in Canada are the Legislative, Executive, and Judicial authorities, ensuring that human rights are enshrined and upheld at various levels of governance.
Step-by-step explanation:
The three layers of human rights protection in Canada are Legislative, Executive, and Judicial authorities. These layers function within a federal system where both the federal and provincial or territorial governments have roles in protecting human rights. The legislative branch makes laws, including those concerning human rights; the executive branch is responsible for enforcing these laws; and the judicial branch interprets laws and ensures they are applied fairly. This separation of powers ensures that human rights are protected at different levels and by different parts of the government, offering a comprehensive framework for their enforcement and protection.
