Thanks, Ms. Kwan.
Certainly it's our position that IRCC should be providing applicants with an opportunity to correct minor deficiencies or perceived deficiencies. As I said, sometimes they're not even deficiencies. There may be a legal or practical reason why a particular document hasn't been included, or it may have been a minor oversight that could be corrected in minutes. Giving applicants an opportunity to correct those deficiencies, as you noted, by picking up the phone or sending an email with even a short deadline to correct it or to explain why it's not there would save resources in the long run by preventing the cascade of additional steps that would need to be taken to fix it.
