I don't know a great deal about art but thought it had an interesting 'African' look to it. She's more versed in art and suggested it resembled the art of the Coptic Christians in Egypt. I thought I would do a little digging.

Fire destroyed the previous Cathedral on July 22, 1968 and the decision was made to rebuild the fifth St. Boniface Cathedral building ! Manitoba architect Étienne Gaboury was chosen to create the design and on July 3 1971 there was a ceremonial sod turning. On July 17 1972 a dedication mass was held inside the new building.

Jesus is actually the work of a diverse Manitoba artist Réal Bérard. Bérard, is a sculptor, illustrator and mapmaker. I recall his illustration work in the great music video for Daniel Lavoie's 'Jours de Plaine' in 1991.
I could not find any articles that went into detail about his Jesus and what his inspiration was. Too bad. Still, one of the more interesting Jesuses (Jesi ?) in the city. Check him out if you can !
