In order to visit Canada, you must have a valid passport, while citizens of certain countries and territories need a visa or an Electronic Travel Authorization (ETA). To find out if you need a visa or an ETA, visit the Citizenship and Immigration Canada website. Depending on your citizenship, you should allow approximately between 30 to 85 days for a visa delivery. Participants who need an official letter of invitation in order to obtain a visa will be able to request it through the abstract submission page. It is important to note that the letter does not constitute any financial commitment on behalf of the Organizing Committee or CALACS.
