Well here is a list of countries by net migration rate: https://www.cia.gov/library/publications/the-world-factbook/rankorder/2112rank.html
Note that net migration rate is not completely the same as Immigration rate. It is " the difference between the number of persons entering and leaving a country during the year per 1,000 persons." You'd have to exclude the leaving ones, to get immigration rate. They don't usually do statistics on that. But if a country has high net migration rate, probably not many people emigrate from it.
However, the simple answer is Canada. Part of the Canadian government policy and Canadian identity is the promotion of diversity and in 2010 the immigrantion rates were set at between 240,000 and 265,000 new immigrants, most coming from Asia.
The country with the largest population of immigrants is the United States, with 45.8 million immigrants. The country with the second largest number of immigrants is Russia, with 11.0 million.
Below are the top 10 nations with most immigrants*:
The US – 46,627,102

Yes unless there was immigration, the country would have a declining population.
The role that immigration plays in population of Canadian country depends on how much immigration is happening in the global surface of Canadian country. The more population = more immigration, therefore meaning that there is also an element of emigration. There are other factors that play a part too, like death rate and birth rate. The more deaths than births, the less populated the certain area will be. VISE-VERSA.
As of now, the country with the highest life expectancy rate in the world is Japan. Japanese people have one of the longest life spans globally, attributed to factors such as a healthy diet, universal healthcare, and an active lifestyle.
