It is all due to transfer of files for out-landers from Mississauga to Sydney. We have no way out but to sit and wait. However if you see more than 2 months have passed; as I read above, something has happened to package, it is being processed but not updated on web or AOR1 will be coming eventually. I think it is about time to phone them:-
IRCC Call Centre (1-888-242-2100), from within Canada only, Monday to Friday, 8am to 4pm local time, except for statutory holidays). May have to go thru all options 2,3,4.
