To support Parallax: Reimagining the Canada-US Border, a collaboratively curated exhibition that presents the plural history of the demarcation of the western Canada-U.S. border along the 49th parallel. Parallax prompts audiences to reconsider the border as a visual invention, revealing how it was drawn through Indigenous lands by American and British officials, astronomers, and engineers in the nineteenth century. A legacy website will be the primary vehicle of post-exhibition research dissemination due to the accessible and expansive nature of its format.
