Indeed, CanLII is a free and extensive online search engine that contains over a million decisions from Canada's courts and administrative tribunals, as well as laws and regulations from across the country. It's a non-governmental organization and it is funded by the Federation of Law Societies of Canada, which is the national coordinating body of Canada's 14 provincial and territorial law societies. Funding for specific projects are also sometimes provided by other levels of government as well. It works with the privately run company, Lexum.
When CanLII started in 2000 it was a bit of an experiment. There are private companies, like Quicklaw, that cost money for access, which lawyers had traditionally accessed. CanLII is part of an international project for free law and access. It has actually grown. It's extensive. It's publicly available. It's used regularly. The reports of its use and expansion is quite progressive.
