In April 1949, Sir Patrick Cooper, Governor of the Hudson’s Bay Company (HBC), advocated for “a simple garden” on an “overgrown and extremely untidy” lot opposite Beaver House, the HBC’s headquarters and warehouses on Great Trinity Lane. The garden would be both of “benefit to the London public” and a way “to remedy the unfavourable impression created to the hundreds of overseas buyers” visiting HBC’s fur auction rooms each year. Over the decade prior, similar requests to build gardens were being sent from the head of the HBC’s Fur Trade Department in Winnipeg, Manitoba, to district and post managers across the Canadian North, with the express goal of making posts “as self-supporting as possible” during wartime and to “provide much needed elements to the diet of our men”, while supporting the federal government in its efforts to promote gardening among First Nations and Inuit. In this paper, I examine the role of HBC gardens and greenhouses during a critical period of transition in the Canadian Arctic, when debates roiled within and between the HBC and the Canadian government over how best to deal with the region’s Inuit, whose rapid integration into the fur trade economy was impacting their capacity to maintain traditional foodways. Drawing on material from the HBC Archives and engaging with discussions of ‘settler colonial urbanism’ underway in critical geography, I place the emergence of these Arctic gardens and greenhouses within ethical and economic debates over Inuit welfare, the decline of the fur trade, assertions of sovereignty over the Arctic, and ultimately, efforts to urbanize the Inuit. Post gardens and greenhouses thus played a role in transforming the dominant metabolic regime, but also in Arctic urbanization.
