Conferences - Invitation Letter Request

Conference speakers or participants coming to Perimeter Institute who require a visa to enter Canada may need a letter of invitation to visit Perimeter. Your application to attend a conference must be approved by the conference organizers before an invitation letter can be issued. 

Letters of invitation will be issued only for the dates of the event.

Please provide all relevant information. Any edits required may delay receipt of the letter further. 

Please allow 10 business days for letters to be prepared and verified.


It is the responsibility of each attendee to verify their visa requirements and ensure compliance with Canadian regulations. Visa applications may require varying processing durations depending on your nationality. We strongly recommend initiating the visa application process well in advance to ensure ample time for processing. To assist you in this process, we've provided links below to resources where you can find information regarding visa applications:
