US citizens and lawful permanent residents of the US do not require a TRV or eTA. They need to include these documents in their TRV application. People who do not require a TRV may require an Electronic Travel Authorization (eTA) to travel to Canada and should bring supporting documents with them as well. If a valid TRV is required, you should send your friend/family member supporting documents. When you invite a friend or family member to visit you in Canada, remember: citizens of certain countries require a valid Temporary Resident Visa (TRV) to enter Canada. Important: Before you invite a friend or family member
