In a good country, government make public places, accommodations, hospitals, police stations, parks, markets, libraries, etc for its inhabitants. With time, if the population grows or is reduced, change of people's choices and for any other reason, the government changes the country's infrastructure, adds new things or demolishes some. They did this based on people's preferences or needs.
If Canada needs more people to work, then it will obviously welcome immigrants to live here. If a new population is added from different cultures, then the country needs to change and add new infrastructure to adjust to it. Otherwise, every place will be too crowded and difficult to manage, increasing people's disappointment in the government, labour misdistribution, traffic problems, unemployment problems, unclean areas, etc.
So, regardless of the country's population, everyone should have proper facilities to live a good life, no matter when they came to the country (two years ago or 200), what their culture is, or what their race is.
