There are all kinds of different tests that are required for immigration depending on the nature of the application.
The IELTS (International English Language Training System) is the standardized test that Citizenship and Immigration Canada (CIC) recognizes as proof of English language ability for immigration purposes.
Some Canadian immigration applicants are required to take the IELTS to demonstrate that they have sufficient English language ability to integrate into Canadian society and the Canadian work force.
