In Alberta, you are subject to laws passed by the provincial government and the federal government. Laws passed in Alberta generally only apply within the province. Laws passed by the federal government apply across Canada.
In addition to legislation passed by governments, Canadian law includes common law. Common law is also called judge-made law because it is a system of rules based on precedent. Whenever a judge makes a decision that is to be legally enforced, this decision becomes a precedent, or a rule that will guide judges in making future decisions in similar cases. The common law is unique because it cannot be found in any code or legislation; it exists only in past decisions. This fact also makes it flexible and adaptable to changing circumstances.
