It depends. Fair dealing is assessed on a case by case basis (i.e., per work). Assessing whether the use of a copyright-protected work qualifies as fair dealing involves an analysis of two broad, subjective, and intentionally ambiguous legal tests. The first legal test considers the purpose for using the work, and the second test will help an individual assess the "fairness" of their dealing. If either test fails, they will need to contact the copyright owner for permission prior to using the material.
Test 1: The dealing must be for a purpose stated in the Act: research, private study, education, satire, parody, criticism, review, or news reporting.
Test 2: The dealing must be fair. This can be determined through the six factors provided by the Supreme Court (excerpted from CCH v. LAW SOCIETY OF UPPER CANADA [2004] 1 S.C.R. 339).
If you are using a work for the purposes of criticism, review or news reporting, the Copyright Act (ss. 29.1 and 29.2) requires that you cite the source and, if given, the name of the work’s creator.
