Carbon tax pass‐through in western Canadian grain transportation

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, Volume 73, Issue 4, Page 339-357, December 2025.
Abstract This paper examines the impact of Canada's federal carbon tax on farmgate grain prices, focusing on pass‐through in the grain transportation sector. The tax, which was eliminated in April 2025 amid concerns about rising food costs, was widely criticized by farmers for increasing expenses related to fertilizer, propane, and rail shipping.
