This is an interesting thread about the actual citizenship Inventory with a 37 pages PDF.
However there is something more interesting about Montreal office when it comes to review the applications
So apparently there are two offices:
Montreal and Montreal CEN. This CEN is somehow very very slow ?! I just wanted to know if this "CEN" has something to do with the email address that you guys received the test invit from ? Mine is also from: DN Cen MTL Convo Eapp / Eapp Convo MTL Cen DN (IRCC)
So did you all receive your test invit from the same email address with "CEN" ?
