Establishing a FAIR, CARE, and Efficient Synthetic Health Data Sharing Ecosystem for Canada
Abstract
Obtaining access to real-world health data is a significant challenge, mainly due to privacy and security implications. Consequently, researchers and technology innovators ̶ particularly those operating in the health data science and AI technology development spaces – increasingly resort to synthetic health data to bridge the data gap. High-quality synthetic data has the potential to expedite research and development of novel technologies. However, synthetic health datasets in Canada are scarce, and no existing synthetic health datasets conform to the Findable, Accessible, Interoperable, and Reusable (FAIR) standards. Moreover, while federated machine learning offers the advantage of protecting patient privacy by not requiring the exchange of source data across nodes, it has yet to be optimized in Canada’s health research environment, and there is limited use of federated learning with synthetic health data. This paper explores the ethical considerations and value proposition of generating and sharing synthetic health data.
Our goal is to facilitate the development of a reliable and sustainable synthetic data infrastructure that
supports the ethical, responsible, and efficient use of synthetic health data. An important contribution of this research is the establishment of a framework that balances the social benefits of innovation from data sharing with the social costs that occur when individual privacy is compromised. The use of synthetic data significantly reduces the potential for individual harm and is a cost-effective means to lower datasharing costs. We believe that this framework will pave the way for a more robust and secure synthetic data ecosystem, enabling the generation of valuable insights that can drive positive health outcomes for Canadians.

The Economics of Canadian Immigration Levels
Abstract
In the hope of addressing chronic labour shortages and sluggish economic growth, the Canadian government plans to increase immigration in the coming years to per capita levels not reached since the 1920s. We argue that economic immigration in the Canadian context should aim to boost GDP per capita in the full population including the newcomers. We then examine the potential for increases in Canadian immigration levels to achieve this objective. Our analysis suggests that Canada is not well-positioned to leverage heightened immigration to boost GDP per capita owing primarily to weak capital investment and quantity-quality tradeoffs in immigrant selection. We conclude by providing a framework for identifying the optimal level of economic immigration
