As someone with a lifelong passion to improve the patient experience of accessing timely and reliable healthcare, I have always been keenly interested in understanding the differing approaches used by government and private sectors around the world in establishing, and evolving, the necessary infrastructure to support this critical human need. As we now face global challenges including growing and aging populations with more complex medical needs than ever before, and seek to apply lessons learned during healthcare crises such as the devastating COVID-19 pandemic, there has never been a more essential time for lawyers around the world to contribute their unique combination of understanding legal regimes, coupled with strong advocacy skills, to lead the changes we all need to ensure a healthy future. Understanding how aged and inadequate healthcare models no longer meet the needs of the people they serve, as well as the complex and costly medical realities of increased life expectancy, insufficient human healthcare resources, and delayed implementation of technological advances, increasing access and creating more consistent and equitable outcomes for patients worldwide is an emerging area of focus for lawyers looking to make a difference in their careers. By practicing in a variety of corporate, not-for-profit and healthcare settings, I have seen firsthand the positive differences that one can make by bringing a sense of urgency in seeking new healthcare models to be supported by both private and public sectors. In exploring these issues in greater depth, this chapter identifies how different models of public private partnerships have and must continue to be implemented around the world to improve timely access to more effectively delivered healthcare on a global basis. We then shift to a comparative analysis of the Canadian and American healthcare systems to illustrate two distinct approaches to providing services and how the best elements of each can be leveraged to create optimal infrastructure. A deeper dive into Ontario, Canada’s most populous province, is then presented as a case study to highlight what progressive changes have been implemented to date, and what further innovation is necessary to improve access to the delivery of sustainable healthcare. Throughout this chapter, by exploring the vast possibilities through the lens of an ESG framework, I highlight and encourage the various ways in which lawyers are empowered, and increasingly relied upon, to create, advocate for and oversee the execution of, public and private sector initiatives to improve access to healthcare and create more effective delivery models. Overall, this chapter aims to illustrate how lawyers who wish to lead in the continued evolution of healthcare must continue to champion the broad application of ESG principles within the legal system to create a healthier world for us all.
