If a valid TRV is required, you should send your friend/family member supporting documents. 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.
Some Canadian visa offices have additional requirements. Go to the IRCC website and select your country/territory from the drop-down menu (located in the "Apply on paper" section). Click "Get documents" and then select "Visa office instructions" (the second link). This will launch a PDF specifying requirements for your visa office. Confirm if additional documents are needed and if the application procedure is different. If applying online:
- To avoid delays or rejection, they will need to submit the required documents listed on the "Your document checklist" page in their MyCIC account plus any visa office-specific documents with their application.
- Merge all visa office-specific documents into one file (such as a PDF) and upload the file in the "Client Information" section under "Optional Documents" in the online checklist.
