This report presents findings from a review of the grey and academic literature and interviews with five Health care in Canada faces geographic barriers to Canadian key informants. access such as large distances between health care delivery centres, population concentrated in the southern part of the country, and a federated health care system.

The Canadian Partnership Against Cancer care. AI is one of these important technologies and has (the Partnership) is the steward of the recently refreshed the potential to change the way cancer care is delivered. 2019-2029 Canadian Strategy for Cancer Control (the In recent years, there has been an explosion of research Strategy), which articulates that technology needs exploring the use of AI in health care, and the AI market to play a more prominent role in accelerating the in health care is expected to grow exponentially going improvement of cancer outcomes for Canadians. forward. Overall in the health sector, some of the largest New technological approaches such as artificial areas of expansion for intelligence (AI) have the potential to ofer solutions AI technologies are expected to be: to these geographic challenges, as well as other challenges in the system. • Process optimization (particularly for back-end processes like procurement and scheduling, While there is no standard definition of AI, it can be as well as clinical flow processes) understood as computer programs and technologies • Preclinical research (e.g., drug discovery) that use processes that resemble human intelligence (e.g., reasoning, learning and adaptation, sensory • Clinical decision support, especially in the understanding, interaction).1 AI includes machine areas of diagnosis and prognostication learning (ML) and deep learning (DL), where machines • Using AI to interact directly with patients provide the analytic power to analyze large amounts of through patient-facing applications data and can make predictions or decisions based on the patterns the machine identifies in the data.
