Citizenship and Immigration Canada (CIC) announced this week that citizens of St. Lucia, St. Vincent and the Grenadines (St. Vincent), Namibia, Botswana and Swaziland will require a visa to travel to Canada, effective 12:01 AM EDT on September 12th.

Individuals who held passports from these countries were previously visa exempt, but due to what CIC says is unreliability in the authenticity of travel documents from these countries, the exemption is being repealed. It was found that citizens from these countries were able to legally change their names and acquire new passports, allowing them to re-enter Canada with new passports after being deported from Canada as security risks.

Visa requirements were also imposed due to the excessively high number of asylum seekers from St. Lucia, St. Vincent and Namibia. The worst offender was Namibia, from which an astonishing 71 percent of those who visited Canada claimed refugee status in 2011, according to CIC.

Commenting on the visa imposition, Citizenship and Immigration Minister Jason Kenney said: “These changes are necessary because all the countries concerned have an immigration violation rate of over thirty percent, well above the level we deem acceptable for countries benefiting from a visa exemption.”

CIC said that the Canadian government regularly reviews the visa requirements it places on other countries, and that countries are aware of the conditions they must meet to receive a visa exemption.
