It would appear that, around 1828, James Ferguson of Scotland established some sort of manufacturing enterprise on Green island, said to have been named after a mister Green, who used its fields for hay and for pasture in the 1830s. Ferguson had been ordered to relinquish the island in 1829, and there does not seem to have been any industrial enterprise on the island during the 1830s. In 1831, however, Colonel By contracted with Jean-Baptiste St-Louis to build a bridge from the mainland to the island. By 1841, Green island had become “Thomas McKay’s land,” and some type of saw mill was operating at the very northern precipice of the island in the 1840s. By 1843, the Ordnance department reported that it had received title to Green island [Grierson 1996].
