Born in Dutton, Ontario, McArthur was educated in Dutton, at Queen's University and at Osgoode Hall.[2] He worked at the Dominion Archives of Canada from 1907 to 1912.[4] In 1915, he was called to the Ontario bar and practised law in Toronto for two years. From 1919 to 1922, he was assistant general manager for a trust company. In 1920, McArthur married Floy Lawson.[2] In 1922, he joined the history department at Queen's University, later serving as department head.[1] In 1934, he became Ontario's Deputy Minister of Education.[4]
