Estimate of the Population of Canada

This is what I came up with when I calculated the population after estimating the birth and death rates of the years following 2011.

Life Expectancy of Canada

The results of the graph show us that the life expectancy of Canadians has increased slightly. I thought it would have increased a lot more; with more people educated, an improvement in medical care, etc. But once I think about it, I realize that there are many people immigrating from countries with a lower life expectancy rate, thus, it takes more time for the life expectancy of Canada to go up.
