Throughout the report, “TMX Group,” “TMX” or “we” or “us” or “our” refers to TMX Group Limited. As reported in our 2023 Sustainability Report, we engaged in a comprehensive and structured review of our sustainability strategy in 2023 to ensure that our sustainability-related initiatives and activities are fully aligned with our purpose to make markets better and empower bold ideas. In the pages that follow, we detail the progress we made in 2024 on implementing that strategy, fulfilling our commitment to measuring and reporting social and environmental impacts, and in particular, to continuing to improve the quality of our data. We regularly monitor the development of sustainability reporting regulations, standards and frameworks for their relevance and usability, along with the expectations of our stakeholders regarding these standards. Our disclosures are informed by and aligned with the Sustainability Accounting Standards Board (SASB) and our reconciliation table can be found in Appendix F. This year, we continued refining our carbon emission accounting exercise by improving inventory quality and quantification processes as set out in the Planet section of this report. We also continue to participate in the annual S&P Global Corporate Sustainability Assessment and CDP Corporate Questionnaire. The performance data footnotes include commentary regarding restatements or data changes, where applicable. All amounts in this document are in Canadian dollars unless otherwise noted. Certain sections of this report may contain forward-looking information as detailed in Endnotes.
