Section 2(1)(a) of Ontario’s Act requires that not only must the person making the application be an “interested person”, but that all other “interested persons” known to the applicant be given notice of the proceedings.

Chard v. Chard, [1955] 3 WLR 954. More than that, it requires in section 2(5)(c ) that the applicant make “reasonable inquiries” to ensure that “no other person has heard of or from the individual during the seven year period”.
