Dear Sir, i am wondering why they are asking for DNA from some people and not from others
This is what i got by email from them
We carefully reviewed the application and documentation submitted. Unfortunately, we are unable to accept the documentary evidence you provided to establish parentage between you and your Son.
In lieu of documentary evidence, we will accept the results of a DNA analysis carried out by a laboratory accredited by the Standards Council of Canada for DNA testing. A list of these private laboratories is attached. You are responsible for covering the costs related to the administration of this test. The Government of Canada assumes no responsibility with regard to the results of these analyses.
These laboratories are not required to be physically present in Canada to be accredited by the SCC, and some laboratories may carry out DNA analysis and retain personal information outside of Canada. Should you elect to undergo DNA testing, you may want to inquire with the accredited laboratory of your choice as to whether laws outside of Canada will apply to your personal information, and what measures they have put into place to protect your information.
If you choose to proceed with DNA testing, we will continue processing the application when we receive the test results. We require an update within 60 days from the date of this letter.
Sincerely,
Program Support Officer
