	In general terms, the CN Group took the following steps during the Reporting Period to prevent and reduce the risk of forced labour or<br>child labour in its business and supply chains:<br>Addressed certain governance and procurement<br>gaps that had previously been identified by the steering<br>committee, as outlined in this Report. The steering<br>committee, comprised of management representatives<br>from Legal, Procurement and Supply Management<br>and Human Resources, previously reviewed the impact<br>of the Act on the CN Group. It conducted a review<br>and gap analysis of the CN Group’s mandates, policies,<br>procedures and contractual clauses related to<br>identifying and addressing risks of forced labour or<br>child labour and promoting human rights within our<br>business and supply chains.<br>Supported the expanded mandate of the<br>Governance and Sustainability Committee of the Board<br>of Directors of CN to review and monitor human rights<br>matters such as the risks of forced labour and child<br>labour within the CN Group’s supply chains.<br>Continued to monitor compliance with our updated<br>Code of Business Conduct (“Code of Conduct”),<br>Procurement Policy and Human Rights Policy, which<br>apply to all our employees in Canada and the United<br>States (“U.S.”). We continue to expect every third party<br>we do business with, including consultants, agents,<br>suppliers and business partners, as well as their<br>respective employees, directors and officers, (collectively<br> “Suppliers”) to obey the law and adhere to high ethical<br>standards, including respecting human rights.<br>Continued to monitor our Supplier Code of Conduct,<br>which was previously updated to clarify that we expect<br>our Suppliers to enforce their own supplier codes of<br>conduct with their supply chain partners and for such<br>codes to include similar obligations as the CN Group’s<br>with respect to reducing the risk of forced labour and/or<br>child labour.<br>Continued to monitor significant tier 1 Suppliers<br>on sustainability criteria, including human rights risks,<br>through third-party cloud-based platforms.<br>Conducted high-level due diligence assessments<br>across the CN Group’s value chain to proactively identify,<br>address, and mitigate potential human rights issues.<br>Engaged with a third-party provider to assess the<br>specific risks of forced labour and child labour in our<br>top 135 tier 1 Suppliers of CN and top 35 tier 1 Suppliers<br>of Autoport.<br>Deployed an in-house questionnaire to survey the<br>tier 1 Suppliers identified by the third-party provider as<br>having moderate and high (previously called moderate<br>high) risk. We designed the questionnaire to obtain<br>information directly from the vendors to develop a better<br>understanding of the potential areas of risk identified<br>by the third-party assessment tool.

	We expect Suppliers to implement our requirements<br>in a manner that is appropriate and proportional to<br>the nature and scale of their activities, the goods that<br>they supply, and the services that they perform. The<br>standards set forth in the Supplier Code operate as a<br>benchmark for acceptable conduct. We expect our<br>Suppliers, where applicable, to enforce their own<br>supplier codes of conduct to their supply chains, with<br>similar obligations as the CN Group’s.<br>The CN Group expects Suppliers to maintain<br>documentation to demonstrate their compliance with<br>the Supplier Code in accordance with applicable laws<br>and the terms of their supplier contract. Suppliers are<br>expected to demonstrate compliance with the Supplier<br>Code upon our request. We reserve and exercise the<br>right to verify compliance with the Supplier Code,<br>including through site visits and inspections by our<br>personnel or designated agents. If a Supplier fails to<br>comply with any aspect of the Supplier Code, we expect<br>the Supplier to immediate notify us of the violation.<br>Further, the Supplier is expected to implement corrective<br>actions immediately to address any contraventions of<br>the Supplier Code to the satisfaction of the CN Group.<br>In the event of non-compliance with the Supplier Code,<br>we may consider such event to be a breach of contract,<br>which we may take into consideration when contracting<br>with the Supplier in the future.<br>Procurement Policy<br>Our internal Procurement Policy defines the key<br>principles, roles and responsibilities that apply to<br>purchasing activities within the CN Group. We aim to<br>conduct procurement activities in a manner that meets<br>operational needs while maximizing opportunities to<br>reduce environmental impact, enhance safety, drive<br>positive social change, mitigate adverse human rights<br>impacts, promote transparency, and otherwise engage<br>Suppliers on our sustainability journey.<br>Our cross-functional Sustainable Procurement<br>Program focuses on integrating sustainability into<br>our procurement process, which encompasses<br>supplier selection, risk assessment, continuous<br>improvement, and capacity building. Sustainability<br>risk, including forced and/or child labour, is<br>considered in the overall assessment of<br>supplier risk.<br>We incorporate sustainability factors into our<br>Supplier selection criteria, including consideration<br>of environmental stewardship, health and safety,<br>ethical practices, and sustainable procurement.<br>In alignment with our Indigenous Reconciliation<br>Action Plan, additional consideration is given to<br>Canadian Indigenous reconciliation activities as<br>we aim to support traditionally under-represented<br>groups, with a focus on Indigenous communities<br>in Canada.

Our Procurement<br>Policy refers to our Human Rights Policy and includes<br>provisions related to the mitigation of adverse human<br>rights impacts within our supply chains.<br>Whistleblower Protections<br>We have established robust whistleblower procedures,<br>and our Human Rights Policy, Code of Conduct and<br>Supplier Code all contain provisions encouraging<br>anyone who becomes aware of a violation of a policy to<br>speak up. The CN Group maintains several channels for<br>employees, suppliers, and others to anonymously report<br>concerns or potential misconduct. These include our<br>Law Department, Human Resources Centre, CN Police<br>Service, and CN Ombudsperson. We also have a<br>confidential CN telephone hotline: 1-800-925-5974.<br>To protect individuals who report violations or file a<br>complaint, each policy prohibits retaliation against any<br>person for reporting, in good faith, contraventions of<br>the policy.

	The CN Group is committed to combatting forced labour and child labour in our operations and<br>supply chains. We conduct high-level due diligence assessments across the CN Group’s value chain<br>to proactively identify, address, and mitigate potential human rights issues. The CN Group has<br>undertaken the following due diligence processes related to assessing risks in our supply chains:<br>We use a custom questionnaire developed<br>in-house by CN to screen selected Suppliers, prior to<br>awarding business, for sustainability issues, including<br>human rights. The Supplier responses are scored<br>by dedicated sustainability personnel. While the<br>questionnaire is not currently used by Autoport, we<br>continue to progress toward using the questionnaire<br>across the entire CN Group over the course of the<br>next reporting period.<br>We use third-party cloud-based platforms to<br>enable us to identify, manage, and monitor the<br>sustainability performance of our Suppliers and<br>assess the specific risks of forced labour and child<br>labour in our supply chains. At Autoport, only<br>suppliers that are also significant Suppliers of CN<br>are currently monitored through these platforms.<br>We have deployed an in-house questionnaire to<br>survey the tier 1 Suppliers identified by the third-party<br>provider as having moderate and high (previously<br>called moderate high) risk. We designed this<br>questionnaire to obtain information directly from the<br>vendors to develop a better understanding of the<br>potential sustainability areas of risk identified by the<br>third-party assessment tool.<br>We have added a specific provision in our<br>standard supplier contracts, which states our<br>expectation that Suppliers must comply with the Act,<br>where applicable, and all applicable laws addressing<br>slavery, human trafficking, and other forms of forced<br>labour.

	OUR APPROACH TO MANAGING OPPORTUNITIES<br>AND RISKS IN OUR SUPPLY CHAIN<br>ASSESSING AND MANAGING RISK<br>Evaluating and addressing the risk of forced labour and child labour in our business and supply chains<br>We previously completed a review and gap analysis<br>of CN Group’s current mandates, policies, procedures,<br>	and contractual clauses as they relate to identifying,<br>addressing, and promoting human rights within our<br>business and supply chains. As a result of the gap analysis,<br>we identified and implemented certain actions, including<br>during the Reporting Period, to help us better assess and<br>mitigate the risk that forced labour or child labour is used<br>in our business or supply chains. These actions include<br>updating our standard contracts to include a provision<br>that our Suppliers must comply, where applicable, with<br>the Act and all applicable laws as they relate to forced<br>and/or child labour. We also added specifications in our<br>Supplier Code of Conduct that Suppliers are expected<br>to enforce their own supplier code of conduct to their<br>suppliers, where applicable, including risk mitigation<br>frameworks in relation to forced and/or child labour.<br>Operations Analysis<br>Given that our workforce is largely comprised of<br>specialized unionized railroaders and office workers,<br>we consider there is a low risk of forced labour or child<br>labour in our direct operations. In addition, the entirety<br>of the CN Group’s workforce is employed or contracted<br>in Canada or the U.S., and the vast majority is employed<br>or contracted directly by the CN Group, not through<br>subcontractors.<br>Supply Chain Analysis<br>As the CN Group procures many goods and services<br>from a broad range of industries, both domestically<br>and internationally, we acknowledge a risk that forced<br>labour and/or child labour may be used in our extended<br>supply chain.<br>We understand the importance of risk mitigation<br>and relationship management throughout the<br>procurement process, including compliance with the<br>Act. To accomplish this, we adopt a multi-pronged<br>approach to managing opportunities and risks in our<br>supply chain, starting with how we select our Suppliers.<br>We seek to gain visibility into our supply chain through<br>the procedures established under our Procurement<br>Policy and Sustainable Procurement Program, as well<br>as screening our Suppliers on sustainability and<br>Indigenous engagement criteria in Canada. We ask<br>significant Suppliers to assess their sustainability<br>performance through a third-party platform.<br>To assess the ongoing sustainability performance of<br>our Suppliers, since 2021, we have partnered with a<br>third party that utilizes a cloud-based platform to help<br>us identify, manage, and monitor the sustainability<br>performance of our Suppliers. We use the sustainability<br>platform to review and onboard critical and other<br>high-spend Suppliers. Currently, critical Suppliers<br>representing approximately 40% of CN’s addressable<br>spend are monitored by the third-party platform.<br>With respect to Autoport, only suppliers that are also<br>significant Suppliers of CN are on the platform.<br>CN utilizes sustainability platform scorecards, which<br>consider country- and industry-specific sustainability<br>risks, to monitor our Suppliers’ sustainability<br>performance. We also use the scorecards to discuss<br>any improvement areas or corrective actions highlighted<br>based on the results of our risk framework. In conjunction<br>with the sustainability platform, we leverage onsite<br>audits and safety performance assessments to assess<br>sustainability issues. In 2025, these assessments covered<br>92% of CN’s critical Suppliers.<br>~40%<br>OF CN’S ADDRESSABLE SUPPLIER<br>SPEND WAS MONITORED ON<br>SUSTAINABILITY ISSUES<br>92 %<br>OF CN’S CRITICAL SUPPLIERS<br>WERE ASSESSED ON<br>SUSTAINABILITY ISSUES<br>2025 Critical Supplier Screening<br>Supplier<br>Selection<br>Supplier<br>Performance<br>Assessment<br>Internal<br>Capacity<br>Building<br>Supplier<br>Audits<br>STEPS TO PREVENT<br>AND REDUCE RISK<br>OUR<br>BUSINESS<br>POLICIES AND<br>PROTECTIONS<br>DUE DILIGENCE<br>PROCESSES<br>APPROVAL,<br>ATTESTATION<br>AND GLOSSARY<br>ASSESSING AND<br>MANAGING RISK<br>08<br>FIGHTING AGAINST FORCED LABOUR AND CHILD LABOUR IN SUPPLY CHAINS<br>2025 ANNUAL REPORT

	MEASURING SUPPLY CHAIN RISK FOR FORCED LABOUR AND CHILD LABOUR<br>Third-party Risk Assessment<br>During the Reporting Period, CN continued to use the<br>services of a third party specializing in risk assessment<br>that utilizes a platform to help us assess the specific risks<br>of forced labour and child labour in our supply chains.<br>This platform provides a risk score for Suppliers using<br>weighted inputs of individual risk components based on<br>country of operations, industry, products and adverse<br>media reports.<br>CN utilized this third-party platform in 2025 to conduct a<br>risk assessment of its top 135 tier 1 Suppliers, representing<br>approximately 70% of CN’s addressable spend. The<br>results of the assessment classified approximately 69%<br>of Suppliers as low risk, 27% of Suppliers as moderate<br>risk, and 4% of Suppliers as high risk (previously called<br>moderate high risk). No Suppliers were identified as<br>elevated risk (previously called high risk). The 4% of<br>Suppliers identified by the study as being high risk<br>provide the CN Group with fleet, rail car, IT hardware,<br>signals and telecommunication products.<br>CN also utilized the platform in 2025 to conduct a risk<br>assessment of the top 35 tier 1 Suppliers of Autoport,<br>representing approximately 70% of its total spend.<br>The results of the assessment classified approximately<br>Remediation Measures<br>The CN Group is committed to providing appropriate<br>remediation measures, in a manner consistent with the<br>UNGPs, where the CN Group has caused or contributed<br>to adverse human rights impacts. However, as we have<br>not identified any instances of suspected or actual forced<br>labour or child labour in our business or supply chain,<br>we have not had to take any measures to remediate any<br>forced labour or child labour. Nor has it been necessary to<br>remediate any loss of income to vulnerable families resulting<br>from measures taken to eliminate the use of forced labour<br>or child labour in our activities or supply chains.<br>Training<br>The CN Group deploys an online training course on<br>its Code of Conduct as part of every new employee’s<br>onboarding program. We require management employees<br>to undergo training on the Code of Conduct every two<br>years, with certification of compliance required annually<br>from each director, executive officer, and management<br>employee. In 2024, we provided training on the issues of<br>forced labour and child labour to approximately 4,400<br>management employees through enhanced training on<br>the Code of Conduct and Human Rights Policy. Refresher<br>training will be rolled out in 2026.<br>Assessing Effectiveness<br>As described in this Report, the CN Group has introduced<br>and implemented several measures to prevent and reduce<br>these risks. However, to date, we have not assessed the<br>effectiveness of these measures.<br>80% of Suppliers as low risk and 20% of Suppliers as<br>moderate risk. No Suppliers were identified as high risk<br>(previously called moderate high risk) or elevated risk<br>(previously called high risk).<br>During the Reporting Period, we deployed an in-house<br>questionnaire to survey the tier 1 Suppliers identified by<br>the third-party provider as having moderate risk and<br>high risk (previously called moderate high risk) in the<br>previous Reporting Period. The results of the assessment<br>demonstrated that 100% of these Suppliers have a<br>framework to manage forced labour and child labour.<br>Approximately 70% of these Suppliers publish a forced<br>labour and child labour report in accordance with<br>their respective local legislative regime. The supporting<br>documents provided by the Suppliers in response to the<br>survey were uploaded to the third-party risk assessment<br>platform to increase the Suppliers’ transparency scores,<br>which increased by an average of 65%. While the<br>questionnaire is not currently used by Autoport, we<br>continue to progress toward using this questionnaire<br>across the entire CN Group over the course of the<br>next reporting period.<br>CN TIER 1 SUPPLIERS<br>(Level of Forced Labour and Child Labour Risk)<br>W 69% Low Risk<br>W 27% Moderate Risk<br>W 4% High Risk<br>W 0% Elevated Risk<br>Based on a risk assessment of CN’s top 135 tier 1 Suppliers, representing<br>approximately 70% of the addressable spend.<br>AUTOPORT TIER 1 SUPPLIERS<br>(Level of Forced Labour and Child Labour Risk)<br>W 80% Low Risk<br>W 20% Moderate Risk<br>W 0% High Risk<br>W 0% Elevated Risk<br>Based on a risk assessment of Autoport’s top 35 tier 1 Suppliers, representing<br>approximately 70% of the addressable spend.<br>~4,400<br>MANAGEMENT EMPLOYEES RECEIVED ENHANCED TRAINING ON<br>HUMAN RIGHTS, INCLUDING THE ISSUES OF FORCED LABOUR<br>AND CHILD LABOUR IN 2024<br>Human Rights Training<br>To learn more, download CN’s Management Information Circular<br>STEPS TO PREVENT<br>AND REDUCE RISK<br>OUR<br>BUSINESS<br>POLICIES AND<br>PROTECTIONS<br>DUE DILIGENCE<br>PROCESSES<br>APPROVAL,<br>ATTESTATION<br>AND GLOSSARY<br>ASSESSING AND<br>MANAGING RISK<br>09<br>FIGHTING AGAINST FORCED LABOUR AND CHILD LABOUR IN SUPPLY CHAINS<br>2025 ANNUAL REPORT
