On September 1, 2010, Citizenship and Immigration Canada announced revisions to its list of designated countries/territories for the purposes of Section 30 of the Immigration and Refugee Protection Regulations.

According to R30, individuals who are seeking entry into Canada for a period of greater than six months and who have resided or sojourned, at any time during the one year period immediately preceding the date of seeking entry, for six consecutive months in a designated country/territory, are required to undergo an immigration medical examination. In addition, regardless of the intended period of stay in Canada, a foreign national who is seeking to work in Canada in an occupation in which the protection of public health is essential will require a medical examination if they are on the list of designated countries.

A designated country/territory is defined as a country/territory with a three year average estimated sputum smear positive pulmonary tuberculosis (TB) incidence rate equal to or greater than 15/100,000. To be considered for removal from the designated country/territory list, a country or territory must remain below the average threshold for three consecutive years.

The following countries/territories were added to the designated country/territory list: (1) Greenland, (2) Nauru, (3) Tuvalu, and (4) and Wallis Futuna.
