Following his return to Scotland, Fraser's cousin, Bishop
John Chisholm appointed him as an underground missionary in
Lochaber. In this wide apostolate, Fraser's duties included overseeing the semi-underground
Lismore Seminary and helping to organize what is now St. Mary's Roman Catholic Church in
Fort William. In 1822, he emigrated to
Nova Scotia. Upon his arrival in Canada, Bishop
Angus Bernard MacEachern introduced him to the
Canadian Gaelic-speaking pioneer communities of
Cape Breton Island and
Antigonish County. Fraser was appointed to
Mabou and in less than a month received added responsibility for the missions surrounding
Bras d'Or Lake. In January 1824 he was given charge of St Ninian’s Roman Catholic Church in
Antigonish, where he remained for the rest of his life. He is said to have been a man of enormous physical strength and to have been able to break steel horseshoes with his bare hands, with legends have been collected of the Bishop's exploits. ==References==
