CanLII

Overview

Founded in 2001, CanLII brings together judgments from Canadian courts, decisions from many federal and provincial administrative tribunals, and consolidated and annual legislation from every Canadian jurisdiction. It also includes legal commentary: books, journals, articles, and reports in its Commentary collection, alongside community case commentary and summaries on CanLII Connects. That breadth makes it useful both for locating primary legal materials and for getting context around them.

Coverage spans federal law, all provinces, and the territories. Case law, statutes and regulations, docket search, commentary, and citation tools are available without a paid plan. One important boundary: the terms prohibit systematic downloading of published documents, including through crawlers, plug-ins, extensions, and connectors, so CanLII is a poor fit for workflows built on bulk collection.

Key features

Flexible search and citation trails

Researchers can search full text, titles, and citations, run note-up searches, and refine results with filters, facets, and sorting. This range is useful when a broad query needs narrowing or when research starts from a known citation. RefLex links cited decisions to other decisions and connects citations to Acts and regulations on CanLII, making it easier to follow authorities within the service.

Saved research and Search+

A registered myCanLII account lets users organize research with folders and alerts. Search+ adds natural-language queries and returns results from CanLII collections with contextual extracts and relevance indicators. It is available to anyone with a free account, but daily usage is limited, so it is best treated as an additional way to explore a question rather than an unlimited research channel. Search+ queries and interactions are stored locally in the browser for history and are not retained in CanLII's systems.

CanLII says personal information is kept in a secure computer environment with restricted access and that it strives to store it in Canada. Its privacy policy also identifies a Clio integration among data stored for myCanLII accounts.

Pricing

CanLII — 0.00 USD per free. The free plan provides access to Canadian legal information, including case law, legislation, commentary, docket search, citation tools, and research alerts. There is no free trial because access is already free. Search+ is included only with a free myCanLII account and remains subject to a daily usage limit. This plan suits readers who need broad access to Canadian materials without a subscription; its main trade-offs are the Search+ cap and the restriction on systematic downloading.

Platforms

CanLII is available on the web. That makes it suited to browser-based research, rather than readers seeking a dedicated desktop or mobile app.

Who it's for

CanLII is a strong choice for legal professionals and members of the public researching Canadian cases, legislation, and commentary across jurisdictions. It is particularly useful when cost matters or research requires moving between primary law and citation trails. Readers who depend on bulk document acquisition should choose another workflow.

Pros and cons

• Pro: Free access spans court and tribunal decisions, legislation, commentary, and dockets across Canada, making it practical for broad research without a subscription.
• Pro: RefLex links cited authorities, while search filters, facets, and sorting give researchers several ways to narrow results.
• Pro: myCanLII folders and alerts help registered users keep research organized.
• Con: Search+ requires a free account and has a daily usage limit, which constrains reliance on natural-language research.
• Con: The terms prohibit systematic downloading, ruling out bulk-collection approaches using crawlers, plug-ins, extensions, or connectors.

Verdict
