Michael Dunahee disappeared from the school playground at Blanshard elementary March 24, 1991, sparking one of the biggest investigations in Canadian history.
Media reports across North America resulted in more than 11,000 tips to police.
Police say one tip has identified a man who could be Dunahee and who lives on B.C.'s mainland.
They say while they don't believe he is the missing child, police will collect his DNA because they have made a commitment to the family to investigate all tips thoroughly until Dunahee is found.
