#PassportTip - If you think your passport may be damaged, you should bring it in to a Passport office and ask one of our officers to examine it. http://www.pptc.gc.ca/service/index.aspx?lang=eng&chkPPTC=on
If your passport is damaged, you should apply for a new one. If you travel with a damaged passport, you could face delays or be denied entry at border crossings, or on flights.
#PassportTip - If you have recently changed your address and your passport is still valid, you may simply cross out the old address and write in the new one by hand, beside. Do not use correction fluid.
