Is migration to Canada actually unadvisable?

Posted January 17th, 2011 by immigratecanada and filed in Immigration to Canada

I am from Nigeria on U.S on a valid work visa.
How much do you think the facts on http://www.notcanada.com/
are correct?
Is it actually that bad?
Can anyone please clarify?

Thanks

Are the reasons mentioned on the site correct or are they exaggerated?
Can anyone please advise?
Thanks
