Per the invitation email for the Oath, dont you need to wait 2 business days before you apply?
"· Please keep in mind that you must wait a minimum of 2 business days after your citizenship ceremony to apply for a Canadian Passport."
A member of my family had in-person oath ceremony today -
-only paper certificate provided, but looks nice, no complaints on that (although had asked for e-certificate);
-was told that must wait three days before applying for passport. Wasn't clear from the version I heard whether they meant business days or just because a friday. Not in a rush anyway.
I still suspect that this is mainly about the certificates given out at the in-person ceremonies. After all, they will have had them printed out in advance, then there will be some no-shows, and so they must have some procedure to 'confirm' that oath administered and to activate certificate. (And some procedure to deal with the no-shows and the leftover certificates.)
But I've no way to confirm my suspicion (at least, no ways that would require no work whatsoever, my hard requirement for a topic I don't care much about.)
