A Charter of Liberties is a document that sets out your rights and freedoms – like a set of rules that makes sure the government treats everyone fairly. It might say what things you have a right to do or have, and that the government can't take them away from you without a really good reason. If the government breaks these rules it means they can be held accountable for their actions. Basically, it's like a list of your rights that you can't be taken away from you.
