On the upside, if this delay does continue then pretty soon I'm going to be able to give the forum feedback on what happens if you try to re-enter Canada from the US as a Canadian citizen with no citizenship certificate and no passport. I'm sure the result will be extremely informative and entertaining.The entire process is a nightmare and needs to be revamped. Imagine waiting since 2019 and they can’t even get it right in the last leg. This causes me anxiety. I did my oath on the 7th and my file closed on the 9th. I have not received anything yet. I sent an email asking Mississauga to confirm if it has been mailed and no response. I have a flight on April and I did mention this. The clerk told me on the 7th she would mail my certificate on the 14th the latest. I live in Brampton how long does mail really take? Crazy. We should have gotten the option to pick it up after oath. At this point they are making excuses.
(I am moving in 2 weeks and then going to the States immediately afterward for another two weeks. I'm going with or without this certificate because time isn't standing still and I'm tired of waiting for IRCC/Canada Post/Passport Canada to decide whether or not they'll allow me to move forward with life).
