老實說,老貓不了解加國的法律,但是老貓所知,如果您已經取得加國的居留權,您應該不會被要求強制離境,但是如果您有HIV,想申請加國的居留權,您可能會有困難,您應該參考這個資料有關加國的部份

下面是一個評論有關這個"新"的法律

A British Columbia advocacy group is concerned that a new HIV reporting law could make people apprehensive about getting tested. Beginning May 1, the law requires that public health officials be notified when a person tests positive for HIV, but it does not require a patient to divulge sexual partners or force a person to notify others of a positive test. Public health nurses will not know the name of the patient, just the name of his or her doctor. "Some may interpret it as mandatory, others may interpret it as voluntary," said Paul Legace, of the Red River HIV/AIDS Network. The law specifically requires a patient's consent because health authorities do not want to deter people from testing, said Tim Christie, an ethicist for the Center of Excellence in HIV/AIDS and co-author of a reportability study in British Columbia. "This is not an adversarial, us-and-them approach," said Christie. "Patients always have a choice." British Columbia is the last province in Canada to require HIV reporting.
