Coat of arms of the Canadian Cardinal Aloysius Ambrozic, Archbishop of Toronto (1990–2006). 
The principal charge of the shield is the gold winged lion, symbolizing the Risen Lord. The lion is also symbolic of Saint Mark in whose Gospel the Cardinal did his doctoral studies. In base the crescent chequy is taken from the arms of the former duchy of Carniola, now part of Slovenia, where the Cardinal way born.
The Cardinal’s motto, Jesus est Dominus, (Jesus is Lord) is one of the earliest professions of faith in Jesus Christ.
