Prior to traveling to Canada for DOHaD 2022, please review Citizenship and Immigration Canada's List of Countries Requiring a Visa for Entry to clarify your Visa requirements. The Conference Organizers recommend that if required, you apply for a visa as soon as your attendance is confirmed, as visa requests can often take months to process.
The eTA process is similar to that of the United States ESTA: travelers apply individually online here. Each individual must pay CAD $7 by Visa, Mastercard or American Express, and their eTA is valid for 5 years. Travel agents can apply for their clients, but they cannot charge a fee for this service. For more information about this new requirement, visit the eTA page for videos and fact sheets in multiple language.
