That must be an error in the French version, and I do apologize. The English version clearly states $500,000. On page 4, the fair market value of an exhibit, in other words of the content of the exhibit, must be a minimum of $500,000.
Forgive me. I see that you are talking about the next bullet on the page. Indeed, if the exhibit comprises 100 objects, that means that 50 of those objects must be Canadian or foreign. It is the percentage of the objects included in the exhibit.
