The son of Olafar Petursson, he moved to Foam Lake, Saskatchewan with his family during his first year of life and then moved to Winnipeg nine years later. He was educated at the University of Manitoba, the University of Chicago, the Meadville Theological School. He was an ordained Unitarian minister, and served as an executive member of the Western Canadian Unitarian Council; in the 1930s, he studied at the University of Iceland so as to be able to conduct services in that language. He also served on the Winnipeg School Board from 1942 to 1951, and was a member of the Canadian Mental Health Association, the Winnipeg Municipal Hospital Commission, and the Welfare Council of Winnipeg. He ran again the federal election of 1965, this time placing third in Winnipeg South Centre against Progressive Conservative Gordon Churchill and Liberal Fred Douglas.
Petursson was elected to the Manitoba legislature in the 1966 provincial election, defeating incumbent Progressive Conservative Richard Seaborn in the north-end Winnipeg riding of Wellington.
