"The Fair Use Clause for Canada, as I've shown, is far more strict and does not allow for a reprint of entire works. Americas law does."
How exactly?
Fair use is decided by courts on a case-by-case basis after balancing the four factors listed in section 107 of the Copyright Act. Those factors are:
The purpose and character of the use of copyrighted work
Transformative quality - Is the new work the same as the copyrighted work, or have you transformed the original work, using it in a new and different way?
Commercial or noncommercial - Will you make money from the new work, or is it intended for nonprofit, educational, or personal purposes? Commercial uses can still be fair uses, but courts are more likely to find fair use where the use is for noncommercial purposes.
The nature of the copyrighted work
A particular use is more likely to be considered fair when the copied work is factual rather than creative.
The amount and substantiality of the portion used in relation to the copyrighted work as a whole
How much of the copyrighted work did you use in the new work? Copying nearly all of the original work, or copying its "heart," may weigh against fair use. But "how much is too much" depends on the purpose of the second use. Parodies, for example, may need to make extensive use of an original work to get the point across.2
The effect of the use upon the potential market for or value of the copyrighted work
This factor applies even if the original is given away for free. If you use the copied work in a way that substitutes for the original in the market, that will weigh against fair use. Uses of copyrighted material that serve a different audience or purpose are more likely to be considered fair.
