Given that Canada doesn't host frontier developers, has a market less than 10% the size of the EU's, and recently caved on its digital services tax under US pressure, what's actually on the table? Kathrin argues that Canada may not need to focus on regulating frontier developers, but could ensure there's no safe haven here, team up with the EU, and prepare for the most severe AI risks through resilience-building and fiscal shock planning. ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions

The literature on biomedical conflicts of interest tends to focus on the ways in which research integrity and patient safety are prejudiced when researchers are funded by the Pharmaceutical Industry. But similar ethical problems also arise at the macro level when institutions, such as hospitals and universities depend on drug company funding to support research or patient care. Over the past half century, the University of Toronto and three of its affiliated hospitals — Sick Kids, CAMH, and UHN — have been involved in a series of major scandals. One scandal in particular — involving the U of T, Sick Kids Hospital, Apotex and Dr. Nancy Olivieri — achieved worldwide infamy and has resulted, to date, in the publication of four books, a blockbuster movie, a plethora of scholarly articles, plus innumerable newspaper and magazine stories and television programmes. Another book is on the way, and a Netflix series is on the cards. In this talk, I'm going to explore the conceptual elements of "conflict of interest" and show how institutional conflict of interest lies at the heart of this greatest of all Canadian academic scandals. I'll also discuss role played by academic leaders and hospital bioethicists. Arthur Schafer https://umanitoba.ca/arts/arthur-schafer Professor Department of Philosophy University of Manitoba **About the Speaker:** Arthur Schafer is a Canadian ethicist specializing in professional and applied ethics, with a special focus on bioethics, philosophy of law, social philosophy and political philosophy.

Schafer has published widely in the fields of moral, social, and political philosophy. He is author of *The Buck Stops Here: Reflections on moral responsibility, democratic accountability and military values*, and co-editor of two books: *Ethics and Animal Experimentation* and *Fragile Freedoms: the global struggle for human rights*. His curriculum vitae lists more than 90 scholarly articles and book chapters, covering a wide range of topics, with a special focus on issues in professional and bio-medical ethics. Professor Schafer is National Research Associate of the Canadian Centre for Policy Alternatives, which has published two of his Reports. Schafer has been a frequent guest on CBC radio and television and has written numerous articles for The Globe and Mail, The Toronto Star, The Winnipeg Free Press, The Medical Post, and The Sunday Times (London). **\* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \* \*** This is a talk with audience Q&A presented by the University of Toronto's Centre for Ethics that is free to attend and open to the public.

The Centre seeks to bring together the theoretical and practical knowledge of diverse scholars, students, public servants and social leaders in order to increase understanding of the ethical dimensions of individual, social, and political life. In pursuit of its interdisciplinary mission, the Centre fosters lines of inquiry such as (1) foundations of ethics, which encompasses the history of ethics and core concepts in the philosophical study of ethics; (2) ethics in action, which relates theory to practice in key domains of social life, including bioethics, business ethics, and ethics in the public sphere; and (3) ethics in translation, which draws upon the rich multiculturalism of the City of Toronto and addresses the ethics of multicultural societies, ethical discourse across religious and cultural boundaries, and the ethics of international society.

When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches. * **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason. * **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes. ## Discussion Questions 1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie. 2. **Can good intentions rescue a bad outcome?** 3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome? 4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend? 5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles? 6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way? 7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time? 8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?

CABS First Friday of the month gaming!!! Door opens at 4pm and will go until the last game is played or the closer for the night needs their sleep.

Welcome to Casual Boardgames, where we enjoy classic tabletop games and social deduction games while bonding over good food, drinks, and great conversations. 
We started this group to meet new people and make new friends, and bonding over games in a relaxed atmosphere is a great way to do that. We currently meet near route 23 and Polaris Parkway, and this is close to areas like Powell, Lewis Center, Worthington, and parts of Westerville and Columbus. 
Feel free to bring your own games or play one of the many games our members bring. If you are inexperienced, we will help you learn. 
Here are just a few examples of the kind of games we play. 
Tabletop/board games: Splendor, Catan, Azul, Dominion, 7 Wonders… 
Social deduction games: Code Names, Chameleon, Werewords… 
IMPORTANT: 
1. While we love playing a variety of games and competing, we are not just about the games. We interact and talk while playing, and this leads to a lot of laughter and fun. If you just want to compete and focus solely on the game, then this is probably not the group you are looking for. 
2. Many people join groups like this and never (or rarely) show up after weeks or months. If you join and never really come, we will eventually remove you from the group as a courtesy to our members. Why? Because limiting group conversations (on the app) to regular members makes communication and planning much easier. Also, while it may be rare, it protects members from people who join because they are interested in following a person instead of having a real interest in our group. If you get removed, it is just because you haven’t come, and we follow this protocol as a courtesy to our regular game players.
