Peter, I've been living here for close to 6 years and noted different things. First, the French from France are not really fond of the French from Quebec, primarily because of their accent. If you listen to Quebec French - its not as soundy as the "real" French you've heard. Secondly, Quebecois discriminate not against poor, but rich people, by cheating them when possible and increasing their taxes through social platforms where they can. In the past 2 years alone, certain taxes on rich living have more than doubled. To the point that people in good neighborhoods of the city I am living in are planning a class-action suit against the city government. Something tells me they are NOT going to get anywhere with it. Quebec courts, and city staff are extremely discriminatory as well, and is nothing more than a cash generating machine for the gov. I have seen it happen to someone I know, and although I didn't want to believe them, I then later experienced it on my own.
Take private sector for example. Quebec companies are also highly selective (more than needed) when it comes to hiring practices. Preferences are always given to Quebecois. Here I can just throw ANY number of examples at you. I've also spoken with a local university professor about this and he was the one to completely support this, with stories and examples no less interesting.
Perhaps because of all this, the Quebec province has been performing bottom-poor, it has one of the largest debts, there are no jobs (at least for anyone else but Quebecois), productivity and work performances of the hired people are so low that companies are losing clients all the time... to be honest, in the last 2-3 years the city of Montreal took a huge fall down, and the decline will continue. One of the reasons a lot of English-speaking people are living the province. Something that is on my own 5-year term to-do list.
Best,
