Unfortunately, I am unable to give advice or assist people with their process of gaining Indian status registration. I am not a lawyer, an employee of INAC, an employee of an Indigenous women’s organization, or an employee of a Friendship Centre.

There is a lot of guiding information and links regarding your application here at this link:

On the particular matter of unknown and unstated paternity here is a link to some valuable information:

What I do suggest is that you keep a calendar and a folder of all your information and that when you contact INAC you always have your file name and date of original application on hand and ready.
