Medical tourism—traveling to another country for healthcare—has become a significant phenomenon affecting Canadian healthcare in multiple directions. Canadians may travel abroad seeking care not available, not timely, or not affordable at home. Foreign patients may come to Canada for Canadian expertise or seek publicly funded care to which they're not entitled. The medical tourism landscape raises questions about healthcare adequacy, queue-jumping, commercialization of care, and the responsibilities of healthcare systems to their own populations versus the global healthcare marketplace.
