Which Canadian legislation addresses health care quality in hospitals?

The Canada Health Act is the correct choice as it forms the foundation of publicly funded health care in Canada, emphasizing access to medically necessary hospital and physician services. This legislation outlines the principles that provinces and territories must adhere to in order to receive federal funding, including comprehensiveness, universality, accessibility, portability, and public administration. By establishing these principles, the Canada Health Act plays a crucial role in ensuring that the quality of health care provided in hospitals meets a standard that supports the well-being of all Canadians.

It directly influences health care quality by mandating that provinces ensure access to hospital services without barriers based on financial consideration, ultimately promoting quality care across the country. The other options focus on specific aspects of health care or regulatory matters but do not serve the primary function of ensuring health care quality in a comprehensive manner like the Canada Health Act does.
