Well according to IRCC it is valid proof of citizenship (the E-certificate) and they said it can be used for passport applications but you are right chances of me being in the pilot project is basically winning the lottery.The electronic citizenship certificate is just a pilot at this point, so only offered to a small fraction of people. And probably 99% of people wouldn’t even want that, since it might not be as dependable as a physical certificate.
So let’s talk about realistic options - if your oath is virtual, then in order to get the certificate sooner, you can request urgent processing. I requested that during the ceremony registration, when talking to the IRCC officer in the zoom call. I mentioned I needed to travel for business in a few weeks, and (luckily) she accepted that and let me pick up the certificate two days later.
As for the other options, my travel is not business travel nor is it due to death or illness.
Is it even worth asking then for quicker processing? The passport office accepts express and even urgent (next day) processing if you have proof of travel regardless of the reason for the travel. I don't understand why it isn't like that for urgent processing of the certificate.
