I'm not arguing with you, I appreciate your input. I'm trying to understand what might be the concern. This is the part of your post that I didn't understand:
Or do you think it wouldn't be allowed for some other reason? Maybe it's illegal to let someone else mail my application on my behalf? Or something else?
I am in Canada at the time when I fill in the application.The very first question on the passport application page is where are you applying from
Are you suggesting other point in time should be considered for "where are you applying from" than the time the application is filled? The time they receive the application? The time they process it?The implication is your plan wouldn’t be allowed
