Health Canada is the federal department responsible for helping Canadians maintain and improve their health. It regulates products we use, monitors safety, provides health information, and supports health system improvement.

Understanding what Health Canada actually does, how it's organized, and where its authority reaches reveals the architecture of federal health involvement in Canadians' lives.
