My original birth certificate was lost when I was trying to mail it. Can I file PR application with a government-authorized copy of my birth certificate?

When you submit your application, you only need a digital/scanned copy of your documents. However, after your application’s approval, you must present all the original documents to the ICA office to obtain your PR certificate. A PR application takes over six months to process, giving you enough time to get your birth certificate reissued in your home country.

If your original birth certificate is not available then the government issued authorized copy is ok.
