If you are travelling with a passport:
When you arrived in Canada and gave your passport to the officer, they placed a stamp in your passport and/or issued another document. Check your passport. If you find a stamp, it should look like one of these.
For example, if the officer placed a hand written date as shown above, your temporary resident status would expire on that date (June 30th, 1993 in this case).
If there is no stamp, a handwritten date or document in your passport, your temporary resident status will expire six months from the day you arrived in Canada.
If you were given a visitor record, study or work permit, the expiry date is marked on the document.
