Final answer:
The Canada Health Transfer, Canada Social Transfer, OAS, and GIS represent Canada's social safety net programs, designed to provide security for health and retirement to beneficiaries. They use a pay-as-you-go system funded by current workers but face challenges as the population ages, requiring policy reforms to ensure sustainability.
Step-by-step explanation:
The promise to pay the Canada Health Transfer (CHT), the Canada Social Transfer (CST), and benefits for retired and elderly people such as Old Age Security (OAS) and Guaranteed Income Supplement (GIS) is an example of the social safety net programs of the Canadian government. These programs are designed to ensure that citizens are secure in their health or retirement. Through transfer payments, these programs represent the government's role in providing social security and health benefits without receiving a good or service in return, effectively enabling recipients to participate in the economy.
Countries like Canada utilize systems such as pay-as-you-go, where the payments of current workers help fund current benefits. However, these systems face sustainability challenges, especially as populations age and the proportion of workers to retirees shifts. Public policy decisions are required to address how to pay for promised levels of benefits, which could involve reforms like adjusting the age of receiving benefits, or changing payroll tax rates to maintain the system's viability.
