how we know whether we are qualified for immigration to Australia or Canada?
Firstly you need to stop spamming the website with "immigration". If you are doing that to get answers no one will answer you because you will come across as annoying. Secondly I would go to an immigrations HQ or something to enquire about this.

Check on the government site or check on the site galstyanimmigrationlaw.com. Here you will definitely get your answer.
Go to the official Canadian government website: http://www.cic.gc.ca/
