If you entered Canada as a visitor, you would have entered on one of two documents:
An electronic travel authorization (eTA)
A visitor visa (also called a temporary resident visa)
If you would like to stay in Canada longer, you need to apply for a visitor record.
What is a visitor record?
A visitor record isn’t a visa. It is a record that gives you status in Canada and permits you to stay in Canada legitimately. Your visitor record will have an expiry date, so, all things considered you should leave the country or present another expansion to stay in Canada legitimately.
A visitor record does not guarantee you re-entry to Canada should you choose to leave the country.
Extending your stay as a temporary resident
If you are a visitor, temporary worker, or student, you may apply to renew your status.
When to apply
If you want to extend your stay as a visitor or change your status (from an international student to a visitor, for example), you should apply at least 30 days before your current status expires.
Where to find expiry date:
The stamp in your passport (this is NOT the date included on your visitor visa)
If you don’t have a stamp in your passport, the expiry date is 6 months from the day you entered Canada
Your study Permit
Your work Permit or
Your visitor record (if you’ve already extended your stay)
