Question: Passage: McGillivray returned to Montreal in 1793 and then took a trip to Scotland and England. He was now a partner in McTavish, Frobisher & Co., who controlled the NWC. With John Gregory, he was sent to manage the company's huge depot at Grand Portage, stirring jealousy among some of the other partners. When Joseph Frobisher retired in 1798, McGillivray took his place. He set up an agency at New York City to get around the East India Company's monopoly enabling them to trade with China. He was closely involved too with the firm of McTavish, Fraser & Co., at London, managed by another relation of his uncle's, John Fraser. In 1803, he helped organize the move of the NWC's main depot from Grand Portage to Thunder Bay. All this time he was dealing with relations with the Hudson's Bay Company and the splinter XY Company that had broken away from the NWC, led by John Richardson.
