Can I cross out a mistake on a passport application in Canada?
You can if you filled out the application form on paper. Line out the error (so that error itself is still readable) and initial. Write in the correct information. Do not use correction fluids or tapes. However, this is the 21st century. A Canadian passport application form is now a fillable PDF document that can not only be filled in on a computer, doing so generates a 2D barcode that Passport Canada can scan to instantly populate the information on ones application into IRCCs computer system. Passport Canada strongly recommends using the fillable form. It makes their job easier, both in reading the application form and entering it into their computer database.
