You are receiving incorrect information. No issue with receiving PR while having to do medical surveillance. Public health will likely monitor your spouse once in Canada because TB can be missed if not a good sputum sample for example. He will likely just be monitored and asked to report any symptoms like fevers, cough that lasts more than a week, etc. TB is fairly uncommon in Canada except in a few populations like on reserves, homeless and asylum seekers and Canada wants to attempt to keep it that way. He will not be required to do treatment if he doesn’t have a confirmed TB diagnosis.
