The eTA is a document that allows you to travel in Canada by plane and to travel freely inside the country. It is an entry requirement for visa-exempt foreign nationals travelling to or transiting through Canada by air. Applying for an eTA is a simple online process. You should apply for an eTA before you book your flight. For more information about the process, see the Electronic travel authorization (eTA).

If a Canadian contact address is required for your visa application, please use the following:
1100 Notre-Dame St W,
Montreal, Quebec H3C 1K3
and use the general chairs as contact.

To check the entry requirements by country/territory, see the following link.


ACM is able to provide visa support letters to attendees as well as authors with accepted papers, posters, or members of the conference committee.

For visa support letters, refer all requests to supportletters@acm.org. Please allow up to 10 business days to receive a letter. All requests are handled in the order they are received. The information below should be included with the request:

  • Your name as it appears on your passport
  • Your current postal mailing address
  • The name of the conference you are registering for. Only accepted authors may request a visa support letter prior to registering for the conference.
  • Your registration confirmation number
  • If you have any papers accepted for the conference, please provide the title and indicate whether you are the “sole author” or a “co-author”
  • Authors may indicate their paper title. If no paper, speakers can provide the title of their presentation
  • ACM does not provide letters for transport of vendor or presenter equipment. ACM suggests shipping the materials insured to the conference facility.


    You must use ArriveCAN to provide mandatory travel and public health information before and after your entry into Canada. ArriveCAN is not only keeping travellers safe, but is part of our ongoing efforts to modernize cross-border travel.
