5. Specifics to the issue of Unknown and Unstated Paternity:

“the unstated or unknown parent issue: in response to the Ontario Court of Appeal’s Gehl decision, which deals with unstated/unknown parent issue, Bill S-3 provides flexibility for the Indian Registrar to consider various forms of evidence in determining eligibility for registration in situations of an unstated or unknown parent, grand-parent or other ancestor.”

6. Specifics to the entire Bill S-3 (This text is copied and pasted from the Government of Canada Website):

Bill S-3, An Act to amend the Indian Act in response to the Superior Court of Quebec decision in Descheneaux c. Canada (Procureur général), was introduced in direct response to the Descheneaux decision. The legislative amendments brought forward by Bill S-3 eliminate the sex-based inequities identified by the court in the Descheneaux case as well as other sex-based inequities in registration.

Bill S-3 addresses sex-based inequities in the Indian registration provisions of the Indian Act for the following situations:

- the cousins issue: differential treatment of first cousins whose grandmother lost status due to marriage with a non-Indian before April 17, 1985

- the siblings issue: differential treatment of women who were born out of wedlock to Indian fathers between September 4, 1951 and April 17, 1985
the issue of omitted minor children: differential treatment of minor children who were born of Indian parents or of an Indian mother, but could lose entitlement to Indian status, between September 4, 1951 and April 17, 1985, if they were still unmarried minors at the time of their mother's marriage

- the unstated or unknown parent issue: in response to the Ontario Court of Appeal’s Gehl decision, which deals with unstated/unknown parent issue, Bill S-3 provides flexibility for the Indian Registrar to consider various forms of evidence in determining eligibility for registration in situations of an unstated or unknown parent, grand-parent or other ancestor.

- The bill also includes provisions to remove the 1951 cut-off. All descendants born prior to April 17, 1985 (or of a marriage prior to that date) of women who were removed from band lists or not considered Indians because of their marriage to a non-Indian man will be entitled to 6(1) status. This will include circumstances prior to 1951 and will remedy inequities back to the 1869 Gradual Enfranchisement Act.

The whole of Bill S-3 is now in force. Provisions to remove the 1951 cut-off came into effect on August 15, 2019.
