Austere throughout his life, he became more and more humble in his way of living and turned toward contemplation and simple duties. As Timothy Pearson explained in "Becoming holy in early Canada": "Charity, both the love one bore for God and the public acts of altruistic gift-giving […] became the prominent trope of holiness after 1650". Saint-Vallier, following the example of the ‘Saints’, showed his generosity by helping the poor and the Hôpital Général of Quebec. He also took very seriously his duties of Bishop and developed parishes in the farthest corners of the diocese. Weak from sickness, he died the 26th December 1727 in the Hôpital Général, which he founded. His last words showed his charity, for he said: "Forget me, but do not forget my poor".
