How many cases are there of tuberculosis in Canada?

There are about 1,600 new cases of active TB reported in Canada every year. About 90% of these cases affect 2 main populations:

  • 70% of cases occur among foreign-born individuals
  • 20% of cases occur among Canadian-born Indigenous Peoples

The rate of active TB in Canada is among the lowest in the world. Canada experienced a steady decrease in the rate of TB between the 1940s and 1980s. Since then, the annual numbers have remained about the same.

How many cases are there of tuberculosis around the world?

Worldwide, 9.6 million people are estimated to have fallen ill with TB in 2014. However, only 6 million new cases of TB were reported to the World Health Organization (WHO). This means that worldwide, 37% of new cases went undiagnosed or were not reported.

How does Canada monitor tuberculosis ?

TB is a notifiable disease and legally reportable to the provincial/territorial governments in all provinces and territories.

Cases of active TB are reported to provincial or territorial departments of health. There are no laws in place requiring provinces or territories to report cases or outcome data to the federal government. However, they may voluntarily submit their surveillance data. The federal government uses this data to produce national surveillance reports.
