The University of Ottawa is an officially bilingual university that gives a very significant tuition break for bilingual students. I am pretty sure that this requires that you take some of your classes in English and some of your classes in French. I think that for international students you need to pay the international tuition rate (which is already very reasonable by US standards), but get a 50% break on tuition by being bilingual. Of course you should double check this.
If you are a citizen of France you get a great break on the cost of any university in the province of Quebec. However, I do not know and sort of doubt that this applies to citizens of Morocco. I have not been able to figure out the cost for international students at French language universities in Quebec (my French is not strong enough to be sure that I am reading the web site correctly).
