In law, primary sources are case law (jurisprudence) and legislation (both laws and regulations).
Don't forget, secondary sources are an excellent resource to help find relevant case law and legislation on a certain legal topic. This is particularly true when researching an area of law in which you are not familiar.
Jurisprudence is one of the primary sources of law. It is the decisions rendered by various courts. There are several tools (print and online) available to find them. Do not forget that secondary sources are excellent in order to find jurisprudence about a specific topic as well. After finding a few major cases you can use various tools in order to find more recent decisions about the same topic.
These tools are also available online through Westlaw Canada.
