Global affairs number through hangout will work till 16th sept i believe..
You need to keep trying multiple times till you get connected - it will keep dropping calls because of call volume till you get in queue..
There was an option where you get transferred to ircc from global affairs canada - option 1 1 1 - and then option 2 1 1 0 -just like what
@USProgrammer mentioned- takes you to sponsorship line but same operators - you can enquire about pr apps - looks like this option does not work anymore - i tried doing this yesterday and gave the same volume queue message and dropped my call- give it a try
If you use textme - choose a canadian number for the account - worked for me yesterday - and call the direct line 1888-242-2100 ..
Good luck
