Funny, in my former field of employment, I interacted with many smart ambitious people, many of whom were so sharp and so good at what they did that I was embarrassed to tell them about my own meager abilities. And guess what? They were often people who were brought to Canada as children by immigrant or refugee parents, or were born to those parents after they came to Canada. If you don't believe me, look at the top professions in Canada, find a directory of the members of that profession, and then look to see how many have names that you wouldn't ever see in the Canada of the 1970's or earlier, before non-European immigration increased. In spite of what you say, the numbers indicate that more "smart ambitious people" are arriving in Canada by way of their parents than are leaving what you call "this filthy country".
