He served the Congregation as Director of the "Fondation Saint-Vincent" school in Cap-Haïtien (1989-1991) of the work of Carrefour-Thorland (1998-2004), and as Director and Economer in Pétion-Ville (2004-2010 ).
For the HAI Vice-Province he was Councilor (2000-2007), Delegate for Youth Ministry (2004-2006), for Formation (2006-2007), and Provincial Superior (2010-2016), finding himself having to animate his confreres, Salesian Family and the young people of the country in the difficult phase following the terrible earthquake of 12 January 2010.
Appointed bishop in June 2016 by Pope Francis, he received episcopal ordination on the following 27 August.
"We ask the faithful, men and women religious, members of the Salesian Family, collaborators and friends and all those who knew him to continue to pray for his soul's rest," said the Salesians of Haiti in a statement. They concluded by stating: “In the certainty that not even death can separate Msgr. Ducange from the Love of Christ, mentioned in his episcopal motto - Caritas Christi Urget Nos (the Love of Christ drives us) - strengthened by the death and resurrection of Christ, let us enter into the hope that believes and that loves."
