I have raised webforms to that effect last year, which were promptly ignored. I will do it again soon, but it is a bit early since it has only been a couple of weeks since I submitted some upfront docs. Also I'm Sept 2020 AOR, so I just crossed the 18 month mark. I will probably send a performance request within a month and if there is no reply, go forward with at least the filing stage of Mandamus. The only thing I'm wondering is, if say IRCC doesn't want to settle and proceed with the case, then can I choose not to do that and stop at that stage, so that I don't have to pay potentially tens of thousands of dollars of legal feels. In other words, can I use the filing stage as a bluff? I would not think twice about paying a couple thousand dollars if that is indeed the case, since the success rate seems pretty high.
