Hi Jason. We ask the living, who are far from glorified Saints, to pray for us. We can certainly do it for the departed. Canonization simply means that they are given a liturgical canon, and "glorification" signifying that we recognize the full glorification of the person. Remember even in the parable of the rich man, in Hades the rich man interceded for his brethren! But again, going back to the fact that we sinful men ask for each others intercessions and prayers in the flesh, there is certainly nothing wrong with one who has departed this life as an exceptional Orthodox Christian for their intercessions, even before glorification.
