On Friday 4 March 2019, Pope Francis raised it to a metropolitan archdiocese, with three suffragan dioceses- two had been part of the La Plata Province and one had been part of the Buenos Aires Province. He accepted the resignation of Archbishop Agustin Roberto Radrizzani, S.D.B., who had been in office since 2007, and appointed as the first metropolitan archbishop the then-auxiliary bishop of the archdiocese, Jorge Eduardo Scheinig, who had been titular bishop of Ita, having been consecrated a bishop in 2017.[1]

The suffragan dioceses are Merlo-Moreno, Nueve de Julio, and Zárate-Campana. The first had been in the Buenos Aires province, and the other two were in the La Plata province.
