The Archbishop’s personal coat of arms (on the right half of the shield) is impaled with the Archdiocesan coat of arms to indicate his office as Archbishop of Winnipeg.

The field of the shield is blue. Blue represents the many lakes and rivers which make up the life blood of the land. A gold cross is placed on it, with the four arms extending to the edges of the shield. This includes the red heart, which is the emblem of the Sacred Heart of Jesus Caritas movement. The Gold Cross indicates that Bishop Murray Chatlain was ordained on the Feast of the Triumph of the Cross. The sacred drum on the top right corner of the shield represents the strength of the spirituality and culture of Indigenous people. The stole in the shape of the letter “M” in the bottom left corner symbolizes the gift of the priesthood in Archbishop Murray’s own life and for the people. The “M” represents Mother Mary’s presence and help.

Above the shield is the green hat with ten tassels at either side, which signals that these are the arms of a Roman Catholic Archbishop. The shield is placed on a gold archiepiscopal cross as an additional mark of Office. The Archbishop has chosen as his motto: “The Almighty has done great things for us” from Psalm 126.
