While the Vatican Council defined Papal Infallibility, it was merely a clarification of the authority bestowed by Christ. However, I don't believe that canonization in a papal prounouncement of dogma concerning matters of faith and morals. Canonization, in the early Church, was an honor bestowed on Christ's chosen Apostles and the fathers of the Church. Later it became a more formalized process. This process required proof that beatified ("saintly") persons be shown to have performed miracles through intercession or that after their deaths that prayers for their intercession resulted in miracles for which there is no scientific explanation. However, these determinations of miracles are made by men, there is no claim that these determinations (and subsequent canonizations) are themselves Divine.
Exactly. Categorically. Absolutely. Positively.
