Can I be found medically inadmissible for being a danger to public health or safety, not just cost?

Yes — excessive demand on health or social services is only one of the medical inadmissibility grounds. A separate basis exists for conditions that a medical officer assesses as posing a genuine danger to public health or public safety, and this ground applies regardless of cost and regardless of whether the applicant would otherwise qualify for an exemption from the excessive demand assessment.

Public health concerns typically involve conditions that could spread to others, such as certain active, untreated communicable diseases, where the risk is about transmission rather than the cost of treating the applicant. Public safety concerns are different again, and generally involve conditions that could cause someone to behave unpredictably or dangerously toward others, assessed based on medical evidence about the condition and its likely course, not simply a diagnosis label.

Because this ground doesn't turn on cost, mitigation plans built around covering expenses privately don't address it — what matters instead is evidence that the specific danger has been managed, treated, or otherwise resolved. Anyone facing a public health or safety-based medical finding needs a response built around the underlying medical risk itself, with current specialist evidence, rather than a financial plan.
