Is Citizenship Judges and officials that administer the citizenship oath are on strike also , the reason for cancelled victual appointment's. Judges and Officials pay grade are very high with lots of benefits not like the permeant IRCC staff that's on strike . So they "the government" hire temporary staff that's not in any part of the union , working as normal to deal with visas ,passport backlogs etc. Why they ain't allocate Citizenship temporary staff to deal with the IT stuff like the work with the immigration Judges , zoom meetings and mailing out the certificates ,Guessing that's what the permanent staff do and deal with this strike situation, just my 2 cents .
