Researching Canadian Case Law: A Step-By-Step Guide

how to research case law in canada

Canada's judicial system is made up of four levels of courts. The first level is composed of provincial and territorial courts, which handle the majority of cases arising under provincial, territorial, and federal law. The second level consists of superior courts, which handle more serious criminal offenses, divorces, and civil cases involving large sums of money. The third level includes the Federal Court and Federal Court of Appeals, which have civil jurisdiction expressly conferred by federal statute. Finally, the Supreme Court of Canada acts as the court of last resort, hearing appeals from lower courts and providing advisory opinions on important matters of law or fact. When researching case law in Canada, it is important to understand this court structure and the types of cases each level handles. There are several online resources and databases that can aid in finding Canadian case law, such as CanLII, Quicklaw, WestlawNext Canada, and Lexis Advance, each offering access to court judgments, case history, and legal commentary.

Researching case law by topic

There are several ways to research case law by topic in Canada. One way is to use secondary sources, such as legal encyclopaedias, textbooks, treatises, annotations, and journal articles, which can point you towards leading cases in a particular area of law or on a specific topic. The Canadian Encyclopedic Digest (CED) is one such resource, which includes commentary, cases, and legislation on a variety of topics. It is organised by a topical classification system, with broad topics such as "Criminal Law - Offences" and narrower sub-topics under each. The Canadian Abridgment Digests is another useful resource, containing summaries of most Canadian reported cases since 1803 and every reported or unreported case since 1986, except for Quebec civil law cases.

Another way to research case law by topic is to use case law databases such as CanLII, WestlawNext Canada, and Lexis Advance. CanLII, or the Canadian Legal Information Institute, is a free legal information website that provides access to court judgments from all Canadian courts, including provincial case law. It also includes decisions from many federal and provincial administrative tribunals. WestlawNext Canada and Lexis Advance also provide access to Canadian case law, although they may require a subscription or access through a university library.

When searching case law databases, keyword searching can be a simple way to get started, especially if your search concept is fairly unique. However, it may not always be the most effective approach as it can retrieve many irrelevant cases. Instead, using topical classification, where cases are labelled according to their subject matter, can be more precise. Additionally, when choosing keywords, keep in mind that case law writing tends to be technical and may favour legalistic wording.

Other resources for researching case law by topic in Canada include books, theses and dissertations, and articles from the Continuing Legal Education branch of the Law Society of Ontario. These sources can provide an accessible entry point for learning about a legal topic and finding related cases.

Using CanLII

CanLII (Canadian Legal Information Institute) is a free and open-source website that provides access to Canadian case law, including federal and provincial/territorial court decisions, tribunal decisions, and legislation. It is a comprehensive resource, offering nearly 400 databases of Canadian case law, with decisions dating back to as early as 1970 and 1876 for Canadian Supreme Court rulings.

When conducting research on CanLII, it is important to understand the meaning of the letters and numbers in the citation, as they indicate the reporter or jurisdiction of the case. The Cardiff Index to Legal Abbreviations database can be a useful tool to decipher these abbreviations. Additionally, utilising Boolean connectors in your search can enhance the effectiveness of your research.

To search for a specific case on CanLII, enter the case name or citation into the Noteup search box. Alternatively, you can locate a case and click on the "cited by" document number. CanLII also offers sophisticated criteria filtering options to refine your search results.

When using CanLII, consider employing a keyword search, especially if your search concept is unique. For instance, a keyword search for "mustard gas" will likely yield more relevant results than a keyword search for a broader term like "insurance fraud". Additionally, CanLII now provides AI-generated subjects, such as "conviction", "criminal", and "rights and freedoms", which can be used to narrow your keyword search to broad areas of law.

CanLII is a user-friendly platform with a consistent layout for searching case law and legislation. It also provides stable links (permalinks) to all resources, ensuring that the links you share remain accessible.

Understanding Canada's court system

Canada's court system is a four-level hierarchy, with each court bound by the rulings of the courts above them, under the principle of stare decisis. The Constitution Act, 1867 provides for the establishment and operation of Canada's judiciary, including its courts of law. It gives the federal government exclusive lawmaking power over criminal law and criminal procedure.

The first level is made up of provincial or territorial courts, which handle the majority of cases arising under provincial, territorial, and federal law. This includes criminal offenses, family law matters (except divorce), juvenile cases, traffic violations, regulatory infractions, and civil claims involving smaller amounts of money. These courts also conduct pre-trial hearings for more serious criminal matters that will be determined by a superior court. Each province has its own set of laws and procedures, and the names and divisions of these courts can vary by jurisdiction.

The second level is the superior courts, which are the highest level of courts within a province or territory. They deal with more serious criminal and civil cases and have the power to review the decisions of the lower provincial and territorial courts. They also handle divorces, civil cases involving large amounts of money, and Charter challenges.

The third level is the provincial or territorial appeal courts. Each province has an appeal court with appellate jurisdiction over the superior trial court. All other avenues of appeal must be exhausted before a case can reach the Supreme Court of Canada, the final court of appeal, and even then, only if granted leave by the Court. The Supreme Court has nine judges representing the four major regions of the country, with three of them from Quebec to represent the civil law system. It hears appeals from decisions of the appeal courts in all provinces and territories, as well as from the Federal Court of Appeal.

The fourth level is the Federal Court system, which includes the Federal Court, Federal Court of Appeal, and the Tax Court. These courts have civil jurisdiction expressly conferred by federal statute and deal with interprovincial and federal-provincial disputes, intellectual property, citizenship appeals, Competition Act cases, and cases involving Crown corporations or government departments. The federal government has also established specialized federal courts, such as the Tax Court of Canada and courts serving the Military Justice System, including the Court Martial Appeal Court.
