Only if immigrants are merely settling empty land. As long as they want to start out as part of society, they'll need jobs, housing and regular infrastructure. My own region is growing nearly as fast as housing can be built. More than 50% of everyone in some cities like Toronto have been in the country for less than 5 years, at any given moment. (Often starting out there, and moving to other parts of Canada later. Still limited by the population capacity of Toronto)
