Cannabis Excise Duty Calculator (Canada)
Supports both price entry methods and correct ad valorem back-out/gross-up. Rates reflect CRA tables as of 2025‑03‑19. Dried/Fresh uses higher of flat vs. ad valorem; Edibles/Extracts/Topicals use flat $/mg THC only. Manitoba has no additional cannabis duty. Adjustment applies to additional cannabis duty when delivered to a purchaser in AB (16.8%), NU (19.3%), ON (3.9%), or SK (6.45%). When ad valorem applies, the province adjustment is computed on the pre‑excise base.
