Prior to his election as bishop, he was the founding rector of the Anglican Church of the Good Samaritan in St. John's, Newfoundland and Labrador.
[2] During the Anglican realignment in 2008, while serving as rector of St. Mary the Virgin in St. John's, Critch was removed from his office by then-Bishop Cyrus Pitman.
He was encouraged to discern a call to Mahajanga by Bill Atwood, the ACNA's dean of international affairs, during the Global South Fellowship of Anglican Churches' Cairo assembly in June 2024.
Critch will continue to live part-time in St. John's, serving at Good Samaritan and fundraising in North America for the Diocese of Mahajanga.
[1] According to ANiC Bishop Dan Gifford, part of Critch's role will be to prepare the diocese―which has just 12 priests―to elect indigenous leadership in the future.
