As of March 15, 2016, all visa-exempt foreign nationals flying to or through Canada will need an Electronic Travel Authorization ("eTA") prior to arriving in Canada. This process is similar to the ESTA program already in effect for travelers to the United States. U.S. citizens and nationals are exempt from this requirement, but lawful permanent residents of the United States must comply. Non-U.S. employees traveling to Canada should plan to obtain an eTA prior to business travel.

In order to register for eTA, the applicant will be required to complete a simple online application and pay a small processing fee of CAD $7.00. Most applicants will receive a decision within minutes of submitting their online application. Upon approval, the eTA will be valid for five (5) years or for the remaining validity of the applicant's passport (whichever period is shorter).
