Additional Travel Information

If coming to Canada as an international traveler 

Visitor Visas (TRV)

All international travelers must carry acceptable identification and a valid visa (if necessary) when entering Canada. Visitors to Canada from certain countries may be required to obtain a Visitor Visa (Temporary Resident Visa TRV). If you require a visitor visa, then it is your responsibility to apply for the visitor visa through your nearest Visa Office.

Processing times are often lengthy; therefore, we encourage you to apply as soon as possible.

A quick online questionnaire here helps you determine if you are from a country whose citizens require a visitor visa. Additional information can be found here.

Applying for a visitor visa can be done online or on paper. If you need help, you can contact your nearest visa application centre (VAC). As part of the application process for a visitor visa you may be required to give biometrics. A list of countries and territories requiring biometrics can be found here, along with helpful instructions on the process and fees involved. Additional travel information and document requirements can be found here.

Electronic Travel Authorization (eTA)

Canada has an entry requirement, known as an Electronic Travel Authorization (eTA), for some visa-exempt foreign nationals who fly to Canada (i.e., it does not apply if you arrive over a land border).

Exceptions include U.S. citizens and travelers with a valid eTA (they are good for up to 5 years).

Click here to find out if this affects you. Additional travel information and document requirements can be found here.

Applying for an eTA is a simple online process that takes just a few minutes. You will need
-your passport
-a credit card
-an email address.

It costs $7 Canadian Dollars (CAD) to get an eTA.

Invitation Letter

The organizing committee understands that official letters of invitation can help to overcome administrative difficulties for Delegates from certain countries. Invitation letters can be generated for symposium participants, but it must be understood that such letters do not represent a commitment to providing any financial assistance or attendance to the symposium. Moreover, such a letter does not guarantee being granted a visa. Please contact us if you require assistance.
