Citizenship and Immigration Canada (CIC) is warning newcomers to be careful of immigration fraud. If you hire someone to help you with your immigration application, you should make sure that they are an authorized immigration representative. If you use an unauthorized representative, you could become a victim of fraud and your application could be refused.
CIC has produced a video to warn people about the dangers of using unauthorized representatives.
