Public healthcare.

Explanation:

Public healthcare is the set of measures and policies designed to meet the health and medical needs of the population, through government action and through the use of public money. Thus, the financing of hospitals, clinics, vaccination plans, etc., by the government, is part of this concept. Its objective is to guarantee access to health for the majority of the population, to prevent the spread of diseases and guarantee a higher standard of living for people. This type of measures is usually financed through the taxes that the government collects, with which countries with this type of system usually charge higher taxes to their citizens, as is the case of Canada.
