The Association of Canadian Travel Agencies (ACTA) would like to help clarify any rumours regarding travel requirements and the H1N1 virus:
Presently, travellers DO NOT need to present proof that they received the H1N1 flu vaccine in order to enter any country except Saudi Arabia. Travellers are encouraged to visit the Department of Foreign Affairs and International Trade web site http://www.dfait.gc.ca for current information on: Travel Reports and Warnings, as well as The Public Health Agency of Canada www.PublicHealth.gc.ca for seasonal flu prevention tips.
These links and other helpful travel information can also be found on our web site at www.ACTA.ca.
Frequently Asked Questions – December 2009
I am traveling and I have been immunized with H1N1 vaccine. Do I need to bring my 2009-2010 flu
history and vaccination record with me?
It is recommended to carry proof of immunization with you when you travel, but not mandatory.
We do recommend that all travellers contact their own physician ideally 4-6 weeks prior to departure. It is important to receive current health information on the countries you plan to visit.
Obtain all necessary vaccinations and preventative medications. It is important to address any special needs.
Immunizations may be recommended or required for countries visited on your itinerary. Example: If you are traveling to (or transiting through) Africa or South America, you may require a certificate of vaccination against yellow fever. This vaccination can be administered only by an approved travel clinic.
It is also a good idea to bring along a record of all your immunizations as requirements for immunizations may change.

The quality of the info is what keeps me on this site, thanks!
Wish You a Merry Christmas.
