Define what life expectancy is and discuss within the context of Canada.

Life expectancy refers to the average number of years a person is expected to live based on current mortality rates. It is a key indicator of the overall health and well-being of a population. In the context of Canada, life expectancy has been steadily increasing over the years due to advancements in healthcare, improved living conditions, and better access to education and resources.

As of 2021, the life expectancy in Canada is around 82 years, with women generally living longer than men. This can be attributed to various factors such as Canada's universal healthcare system, which provides access to medical services for all residents, as well as public health initiatives aimed at promoting healthy lifestyles and preventing diseases.

However, there are also disparities in life expectancy within Canada, with Indigenous populations and those living in lower socioeconomic conditions experiencing shorter life expectancies compared to the national average. This highlights the importance of addressing social determinants of health and ensuring equitable access to healthcare and resources for all Canadians.

Overall, life expectancy in Canada reflects the country's overall commitment to promoting health and well-being for its population, while also highlighting the need for continued efforts to address health inequalities and improve the overall quality of life for all residents.
