She was canonized on October 1st, 2000. She had a relatively short period of time from death to canonization. The two miracles that were founded in the canonization process were; one, a ninth grader, Robert Guntherman, who had an ear ache. His mom brought him to the doctor where he was told that his eardrum was destroyed and he would not be able to hear again. His mother prayed to Katharine and a few months later he was able to hear again.
The second miracle founded in relation to Katharine Drexel was, when a baby named Amy Walls was born with a hearing defect and told he would never be able to hear. Her mother saw a documentary on TV about Robert Guntherman and then she prayed to Katharine and held a relic to the baby's ear and the baby was now able to hear.
