Some people are beginning to realize that the financial viability of our health care system depended upon most taxpayers contributing to the system for most of their lives while healthy and only drawing upon the system heavily during a relatively brief period of retirement.
Our immigration system, especially the family reunification and refugee claimant aspects of the system, upsets the financial balance. Too many immigrants are accessing these resources before they have contributed enough to the system.
Add to that the shortage of family doctors. That shortage affects new Canadians much more frequently than longer term citizens. Without family doctors, people use emergency rooms and emergency services (paramedics) for basic health care. Go to any hospital emergency room and see for yourself.
Immigration of the elderly is not the only problem our health care system faces, but it is a readily visible one.
