Let me guess, in Canada, schools are not run on local taxes?
Even if her father is already in the district, and paying for those schools, I still don't like it. School taxes are usually as high as politically feasible, meaning they will not go up unless property value goes up. So, bringing in out of district students means that fixed amount of money has to be spread through more students resulting in less funding per student.
One or two wont make a considerable difference in most cases, but if the schools don't address the problem, it could become a real problem.
