About case law

Case law is the written or verbal record of judges' decisions in courts. The case law records not only the outcome or decision made by the judge(s) but also the reasons for the decision and the sources (legislation, precedents in previous cases, etc) upon which the decision is based. It is sometimes referred to as "judge-made law".

Case law is one of the two main types of primary law in Canada, which means it is binding in court. The other type of primary law is government-made legislation (also called statute law).

It is helpful to understand how the Canadian court system works in order to search for case law effectively. Click on the "Courts in Canada" tab above more info.

Law reports only include selected cases which are considered to be significant. They typically include "value-added" material provided by the publisher, such as extra headnotes, expert commentary, and finding aids which help you locate and understand relevant cases.
