Fair dealing in Canadian copyright law is a statutory user’s right that allows the reproduction or use of copyrighted material without permission or payment, provided the use is for an allowable purpose and passes a legal “fairness” test. (SFU Library)
Canadian institutions (such as universities) often utilize specific Fair Dealing Policies that provide quantitative guidelines, such as permitting the reproduction of a single short excerpt (like 10% of a work), to ensure compliance with the law.
