It is interesting that there are certain individuals who respond to immigration questions on reddit, Quora, and even here that give the same reasoning for 1) why immigrating to Canada is a bad idea 2) why immigrants are ineligible to apply and why it is not even worth the effort. I just see this as an extension of anti-immigration attitudes that we are seeing in the US, parts of Europe, and to a lesser extent Canada. But the extent of the misinformation and the coordinated effort by the anti-immigration folk is disturbing.
Just do your own research. Use more than one source. Ignore people with a clear bias. Don't let anyone color your view of Canada, the US, or the country to which you want to immigrate.
