You pointed out the fact that it's such a small number. The cost of medical processing of all of these applications is very high. Each person has to go through a medical check, and then the application is reviewed by a medical officer. To screen out, effectively, 900 applicants, one wonders, from a cost-benefit point of view, whether it makes any sense to do that.
In any event, the argument I made was that we should probably just eliminate medical inadmissibility because the number is so small, the costs associated with it are very high, it impedes our ability to compete for the immigrants we need, and it creates a lot of hardship.
