If the work you showcase as in your profile is yours or even you are part of it, then you appear a very productive person able to pull your own weight and hopefully thrive in a place like Canada (or at least Canada of the past). You don't seem to be an asshole either so I will also assume you are not a someone who engages in violence. I would be happy to have immigrants like that. Also most of the immigrants I know think we are letting in way to many of the wrong type of people and propping them up way way too much.
Also yes Canadians used to be strong, hardworking polite nice people those are some of the reasons it was such an amazing place to live.
As far as the mineral extraction Gold Reserve Inc is US company not Canadian, I can't find any record of Rusaro Mining and Crystallex appears to be a private company not saying that's much better but it's not Canada as a country taking your resources in what yes totally appears to be in unethical ways. But that is a private organization taking advantage of the Venezuelan government's happiness to take advantage of it's people and resources (wich I agree is horrible and wrong).
