In 1994, a total of 2,074 people in Canada were diagnosed with tuberculosis, a rate of 7.1 cases per 100,000 population. The same year, tuberculosis and its late effects caused 150 deaths-just over one in every 1,400 deaths. Although tuberculosis is no longer a major health problem in Canada or a leading cause of death, some groups are particularly susceptible to the disease: Aboriginal people, residents of low-income households, immigrants, and the elderly. In the first two instances, the occurrence of tuberculosis is associated with poor living conditions. The risk of tuberculosis among immigrants is high because of the greater likelihood of exposure in their countries of origin. Among the elderly, the potential for developing active tuberculosis is relatively high due to exposure decades ago when the disease was far more prevalent. Since 1980, the rate of pulmonary tuberculosis has declined, while the rate of extra-pulmonary tuberculosis has remained steady. As a result, the proportion of cases attributable to extra-pulmonary tuberculosis has risen.
1994年，加拿大共有2074人被诊断出患有肺结核，发病率为每10万人中有7.1例。同年，肺结核及其晚期并发症导致150人死亡，占总死亡人数的1/1400多一点。尽管肺结核在加拿大已不再是一个主要的健康问题，也不再是主要死因，但一些群体尤其易患此病：原住民、低收入家庭居民、移民和老年人。在前两种情况下，肺结核的发生与生活条件差有关。移民中肺结核的风险较高，因为他们在原籍国接触病菌的可能性更大。在老年人中，由于几十年前疾病更为普遍时的接触史，患活动性肺结核的可能性相对较高。自1980年以来，肺结核发病率有所下降，而非肺结核发病率保持稳定。因此，非肺结核病例所占比例有所上升。
