I am not sure if you guys noticed or it was posted before but this is what is written on page 3 of the Notice to Appear (Ceremony):
You shouldn’t finalize any travel plans until you get your citizenship certificate and then your passport. Before applying for a passport or other government services, you will require your paper citizenship certificate. It may take up to approximately 2 to 4 weeks to receive it. For up-to-date passport information, please consult the Canadian passports and other travel documents: Applying in Canada webpage.
My wife has been waiting for the certificate for 4 weeks now. We called IRCC yesterday and were told that it has not been even sent. The IRCC agent advised us that we should wait for 6 weeks and call them back then. We have a trip in 20 days and made a decision to proceed with the oath based on the writing above and conversation with the agent prior to the ceremony.
I think we should push IRCC by submitting Webforms, calling IRCC and contacting your local MP (I think they will be happy to help you since you can vote after becoming a citizen). IRCC looks really unprofessional and incompetent.
