Why is Quebec usually exempt from Canadian contests?

Question

The small print always says "contest not valid to residents of Quebec". Why is that?

Answer 1

because they are french

Answer 2

All of Canada is governed by English common law and its contract

law. Only Quebec is governed under the Napoleonic code of law that is what the law is in France which has totally different contract law.As it is too difficult to make contest rules to fit both English common law

and the Napoleonic code they just stick with the provinces that are

covered by English common law and skip Quebec.
