Abstract: This paper studies the Canadian mineralogical collections sent to the 1851 Great Exhibition in London and the 1855 Exposition Universelle in Paris. These collections were curated by William Logan, the first director of the Geological Survey of Canada, which operated as a leading institution in mineral exploration, colonial expansion, and settler statecraft in Canada. The 1851 and 1855 exhibitions of Canadian minerals in Europe helped develop and fund the largescale transcontinental Canadian geological surveys that followed in the second half of the nineteenth century. In this paper, I argue that the exhibitions opened pathways for international investment and marked the beginning of the planetary scope of the Canadian mining industry today.
