CanLII is an open-access database of Canadian case law and legislation. It allows you to set up a RSS feed to be notified of all federal and provincial subsequent consideration of a case. To set up a feed:
If your case has not been cited, type or paste the citation into the Noteup box on the CanLII search page - you will get a message saying 'Your search did not match any documents'.
Click on the grey RSS icon on the right-hand side of the page and follow the prompts to create an RSS feed. You will now be notified of any citations to your case.
Feeds can also be set up on CanLII to be notified of new decisions from particular federal and provincial courts, tribunals and boards.
To set up these alerts, see the jurisdictional list of courts and tribunals page and link to the jurisdiction you are interested in. The RSS feeds are all listed.
RSS feeds can be used in CanLII to set up alerts for saved searches, so that you are notified of new cases on your specific topic. This can be further narrowed by only notifying you of decisions in particular courts or tribunals.
