Anyone who is in heaven is a saint, including the angels. Canonization is just the official process by the Church where this is publicly recognized and a Mass and Office are established for a particular person. However, this is rather recent:
St. Patrick died, and entered heaven, and has been celebrated as a saint long before the Church's process of canonization was even conceived.
There was no canonization process in place when Patrick died, that came about in the 12th century. He would have been declared a saint by popular acclamation and his sainthood approved by a local bishop soon after he died in 467. Today only the pope can declare a saint and only after a lengthy canonization process.
