Montreal Diocesan Theological College

It offers the Master of Divinity, Diploma in Ministry, to candidates for ordination and other students, from Anglican, United Church, and other traditions.

Andrew Taylor designed the former Montreal Diocesan Theological College building at University Street near Milton Street, 1895–96,[1] mostly funded by the philanthropist Andrew Frederick Gault.

A World War I memorial window (1935) by Charles William Kelsey depicting Saint Stephen the Martyr was dedicated to Albert Withey of the 24th Canadian Battalion.

Beginning in 2021, the neighbouring United Theological College began to integrate its operations into Dio.

In 2022, UTC's academic offering transitioned into a United Church studies program at Dio, with UTC beginning to wind down its legal existence.
