Up until the first week of August the invite letter to take oath has been mailed out almost immediately following the test, at CIC Calgary. Something changed after the first week of August, now the test takers from second week of August onward have not yet heard back about any progress. CIC helpline is turning down calls, so we're hitting a wall here with no one to respond! not that it was helpful when we were able to talk to an agent! This is really really weird, annoying and baffling as to why put stop to the flow of the process of sending invites past first week of August. I gave my test on 12/Aug and haven't heard back yet.
