Awe, you must be new here!

Welcome to the PSAC pain and suffering club!
If you have the time to read previous posts, you will see that all ceremonies are canceled due to the strike, meaning that if you call IRCC (good luck speaking to someone though), they won't be able to tell you anything anyway.
People that have received the notice to appear previously got an email informing them of the cancelations. If you didn't receive it, it means you won't get any notification whatsoever about the ceremony not happening. And this sums it up.
