I can tell you that the health transfer is on a per capita basis which updates every year. If immigrants are added to the mix, and the per capita costs are calculated every year, then it just comes out in the wash. You've already proven that immigrants have the same costs in health care as everyone else, and the health transfers are the same. If you add more immigrants, it all comes out in the wash.
Why are we forcing the government to quantify immigration if we already know it's the same as the base human population in the country?
