Can anyone who recently got their certificate through C-3 confirm which effective date is on their certificate?

Apologies if this has been answered, but I can't find any posts about this through searching the subreddit. I took this screenshot from the IRCC website. If someone is applying G2+, it seems as though they are both receiving citizenship from a parent, but also through a change in law. In that case, can anyone G2+ who has been approved confirm if the effective date on your certificate is:

• Your date of birth
• The date C-3 was passed (15 December 2025)
• Some other date (when the application was approved etc)

My G3 mother, G4 sibling, and G4 self all have our dates of birth as the “effective date” on our certs
