Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Cybersecurity risk, management, and strategy Tilray recognizes that cybersecurity is critical to protecting our systems, data, and operations. We are committed to addressing the significant risks posed by cyber threats by proactively managing the evolving landscape through a comprehensive, enterprise wide approach. Our enterprise risk management framework considers cybersecurity risk alongside other company risks as part of our overall risk assessment process and shares common methodologies, reporting channels and governance processes that apply across the enterprise risk management framework to other legal, compliance, operational, and financial risk areas. The Company is committed to maintaining robust processes to assess, identify and mitigate material risks from cybersecurity threats and to protect against, detect and respond to cybersecurity incidents. Our business is subject to various cybersecurity risks, including but not limited to, unauthorized access to sensitive data, including customer information and medical information, disruption of operations or supply chain due to cyberattacks, theft or manipulation of intellectual property, such as proprietary strains or cultivation techniques, regulatory non-compliance resulting from cybersecurity breaches, including violations of data privacy laws. To address these risks, we have implemented a comprehensive cybersecurity program, which includes, regular risk assessments and vulnerability testing to identify and remediate potential weaknesses in our infrastructure, deployment of advanced access controls, encryption, and endpoint protection to safeguard sensitive data such as customer and medical information, mandatory annual cybersecurity training and awareness programs for all employees to reduce the risk of social engineering and phishing attacks, and continual monitoring and incident response protocols to detect, contain and respond to cybersecurity incidents in a timely and effective manner. We also have information security and data privacy policies and procedures in place applicable to our directors, officers, employees, contractors and suppliers. Third parties service providers also contribute to our overall cybersecurity. We engage third parties that are cybersecurity experts to support in the design, implementation and continuous improvement of our cybersecurity program. As of the date of this Form 10-K, we do not believe any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations or financial condition. See “Item 1A. Risk Factors” for further information about these risks.
