Number of cases of tuberculosis in Canada

There are about 1,600 new cases of active TB reported in Canada every year.  In 2016, 89% of these cases affected 2 main populations:

  • 70% of cases occurred among foreign-born individuals
  • 19% of cases occurred 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.

Number of cases of tuberculosis around the world

Worldwide, 10.4 million people were estimated to have fallen ill with TB in 2016. However, only 6.3 million new cases of TB were reported to the World Health Organization (WHO). This means that worldwide, 39% of new cases went undiagnosed or were not reported.

How Canada monitor tuberculosis

There are no laws in place requiring provinces or territories to report cases or outcome data to the federal government. However, they all voluntarily submit their surveillance data. The federal government uses these data to produce national surveillance reports.
