Yes. Posting something on your own website means you are making the work openly available worldwide. Wide distribution tends toward the conclusion that the dealing is not “fair,” and such uses are unlikely to be covered by any University licences. By contrast, Waterloo's learning management systems are password-protected, secure websites that are accessible to students enrolled in university courses. In some cases, posting material on a learning management system will be covered by one of the University’s electronic subscriptions. The key thing to remember is just because you may post a copyright-protected work to a learning management system doesn’t mean you have permission to post the work to an external website.
