From Archdiocese of Toronto:
On the Solemnity of the Annunciation of Our Lord (April 8), parishes throughout the Archdiocese of Toronto took the opportunity to participate in the archdiocesan-wide Consecration of the Blessed Virgin Mary.
The Annunciation of Our Lord is usually celebrated annually on March 25 however, for 2024 it was transferred to April 8 due to the date of Easter.
