A Temporary Resident Visa (TRV) allows foreign nationals to visit Canada for a temporary period. It is required for citizens from visa-exempt countries. To apply, you must complete an application, provide supporting documents (like proof of funds, a travel itinerary, and ties to your home country), and pay the processing fee. As a visitor, you can stay for up to 6 months. TRVs do not grant the right to work or study, but you may apply for extensions or a work permit while in Canada.
