When you arrived in Canada and gave your passport to the officer, they authorized your stay by placing a stamp in your passport and/or issuing an additional document. Check your passport. If you find a stamp, it should look like one of these.
For example, if the officer specified a date as shown in the above illustration, your temporary resident status would expire on June 30th, 1993.
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.
