Before an officer can say your health is a danger to public health, three things have to be weighed: what the doctor or laboratory actually reported, how communicable the condition is, and what it could do to people already living here. A diagnosis on its own is not the test. The question is transmission and consequence.
31 Before opining whether a foreign national’s health condition is likely to be a danger to public health, an officer who is assessing the foreign national’s health condition shall consider (a)any report made by a health practitioner or medical laboratory with respect to the foreign national; (b)the communicability of any disease that the foreign national is affected by or carries; and (c)the impact that the disease could have on other persons living in Canada.
