Brazil, which previously announced at last year’s World Travel Market (WTM) that it will be granting 90-day visa exemptions for several nations including Canada, has recently confirmed that June 1 will be the start date for the waiver period.

The measure will be valid only for trips that take place exclusively between June 1 and Sept. 18, 2016 for tourists from Canada, the United States, Australia and Japan. The exemption from the visa requirement is valid for 90 days. The usual visa requirement for the aforementioned countries will resume on Sept. 19.

Based on bilateral agreements, Brazil already exempts citizens from over 80 countries from needing a tourist visa. In exchange, Brazilians can also travel freely to these countries without a visa since the agreement is based on reciprocity.

The recent move to now offer citizens from Canada, the U.S., Australia and Japan for a limited time was timed to coincide with the upcoming Olympic Games and Paralympics, which will take place in Rio de Janeiro from Aug. 5-21, and Sept. 7-18, respectively.

According to an official memo from the Brazilian Tourism Institute, the exemption of entry visas for these four countries “don’t interfere with the security measures being taken by the Brazilian government for the Olympic and Paralympic Games. The issues related to the security of the Olympics will be processed under Special Security Office for Major Events of the Ministry of justice, which has a national Strategic Plan and a National Tactical Plan to ensure the safety of the Games.”

To ensure all levels of tourism are aware of the new policy, the Brazilian government will be creating a task force to keep the aviation industry informed, which includes airlines and companies that manage airports in Brazil. In due course, the Ministry of Foreign Affairs will update its regulations and inform all authorities.
