He moved to the Churches of St Benedict (Harbour View), the African Martyrs of Uganda (Bull Bay) and Christ the King (Port Royal) in 1972 where he served for some ten years as Pastor of the respective parish(es).

[1][2] On 18 December 1983, Dufour was awarded the Jamaican Prime Minister's Medal of Appreciation; on 18 April 1991 he was appointed an Honorary Prelate of His Holiness[3] and in 1993 he was Chairman of the Organising Committee for Pope John Paul II's visit to the island (9 – 11 August[4]).

On 6 December 1995, it was announced that Dufour was elected by John Paul to be the second Bishop of Montego Bay,[5] after His Holiness had promoted Edgerton Clarke as Archbishop of Kingston the previous year.

He was ordained by Clarke on 10 February, with the latter's immediate predecessor Archbishop Samuel Carter, SJ, and Bishop Paul Boyle, CP, then Vicar Apostolic of Mandeville, as the principal co-consecrators.

On 8 August of the same year he was appointed Apostolic Administrator of Mandeville by Pope Benedict XVI, because His Holiness had on that day accepted the early resignation of Bishop Gordon Bennett, SJ.

On 29 April 2016, four days after a year passed since Dufour turned 75 and submitted his resignation, it was announced that Pope Francis accepted it and promoted Bishop Kenneth Richards of St John's–Basseterre as the seventh Archbishop of Kingston in Jamaica.

[14] Though he has received such dignitaries as the Canadian Prime Minister (Jean Chrétien), the Cuban President (Fidel Castro) and the Spanish Crown (Juan Carlos and Sofía), Dufour has continued working with youth and those in prison.
