I think it may be discriminatory, but I would go in another direction. For the time being, it hasn't yet been proven that these students, who come from French‑speaking Africa, for example, are from poor families. No studies show this. These are middle‑class families who can afford to pay for their children's education, as other people from elsewhere would.
With respect to your question, there is certainly a huge difference between $30,000 and $10,000. Some universities charge an application fee. At UOF, it's $1,000. At the Université de Hearst, I believe it's around $5,000, but I'm not sure. We'd have to check that. Whatever the case may be, these fees must not be prohibitive. We just need to make sure that when parents are paying that kind of money for their child, they are guaranteed that the child will get a visa, because life goes on after that. Sometimes money is paid, but at the end of the day it doesn't lead to a study permit. That puts these people in very difficult situations, and in order to get refunds, they have to go through additional procedures.
To come back to my answer, I would say that it hasn't yet been proven with certainty that the issue of money is necessarily the barrier to obtaining a study permit. A study would have to establish this. In this respect, I would like to see an ombud.
