Income Statement, Balance Sheet and Additional Disclosures by Disposal Groups, Including Discontinued Operations [Line Items]      
Discontinued operations, description On November 16, 2023, BioSteel Sports Nutrition USA LLC (“BioSteel US”) and BioSteel Manufacturing LLC (“BioSteel Manufacturing” and collectively with BioSteel Canada and BioSteel US, the “BioSteel Entities”) were added as additional applicants in the CCAA Proceedings. As a result, the most relevant activity of both entities became the liquidation and sale of assets and distribution of cash and proceeds to their respective stakeholders and management concluded that Canopy Growth ceased to have the power to direct the relevant activities of BioSteel US and BioSteel Manufacturing because those activities required approval from the CCAA Court. As a result of the conclusion of the sale of assets and distribution of the cash and proceeds of the BioSteel Entities, on July 31, 2024, the CCAA Court granted an order which provided, among other things, for the termination of the CCAA Proceedings upon service of a certificate (the “CCAA Termination Certificate”) and authorization for the BioSteel Entities to file assignments in bankruptcy pursuant to the Bankruptcy and Insolvency Act. The BioSteel Entities were assigned into bankruptcy as of October 2, 2024. The bankruptcy of the BioSteel Entities will deal with any remaining nominal assets of the BioSteel Entities. The CCAA Termination Certificate was served on October 22, 2024.

Management concluded that Canopy Growth ceased to have the power to direct the relevant activity of BioSteel Canada because the liquidation and sale transactions required approval from the CCAA Court. Thus, Canopy Growth no longer had a controlling interest in BioSteel Canada and had deconsolidated the entity effective September 14, 2023. The deconsolidation of BioSteel Canada and related impairment charges were classified under losses from discontinued operations.
