(died 14 Nov. 1890), lumberman. Born presumably in GC. Parents: John McArthur, lumber merchant, and his wife Margaret McMartin. He established himself as a lumberman in Toronto about 45 years before his death. He was joined in the lumber business there by his brothers Alexander and Peter McArthur. Peter’s obituary in the Toronto Mail & Empire described the firm as “one of the largest lumbering firms in America, their specialty being square timber.” The firm operated in Quebec Province, Ontario, Michigan, “and in later years in the Western and Southern States.” Shortly before John died, the business was reorganized as a joint stock company, with head offices in Toronto and branch offices in Quebec City and Detroit, and with overseas agencies in London, Liverpool, Glasgow and Belfast. John McArthur died in Toronto. Besides those already named, he was the brother of Archibald and R. D. MacArthur.

     It is not clear how much connection the company maintained with GC–probably very little, considering its extensive operations. However, in 1889, the Rayside-MacMaster partnership (James Rayside, Donald MacMaster) brought a huge timber raft, managed by a 40-man crew, to Quebec City in a six-week journey and delivered it there to its purchasers McArthur Bros., of Toronto.
