Travelers flying to Canada starting Sept. 30 will experience a raft of new documentation requirements depending on their citizenship. The rules are part of Canada’s Electronic Travel Authorization (eTA), established in 2011 to facilitate travel between the U.S. and Canada. A result of the eTA was an effort to more closely scrutinize foreign nationals from visa-exempt countries. Up until the eTA, some countries authorized citizens to travel to Canada with only a passport, and without having to obtain a visa. As a result, foreigners from these countries were not subject to any screening until they arrived at an airport in Canada. These foreigners will now have to obtain an eTA in their passport before they can board a plane flying to Canada.
