Got my test invite today. Mississauga on August 8th.
Just to let you know, I submitted a web form 2 weeks ago informing IRCC that I am an early September applicant and it has already passed 10 months and that I do not see my application being processed in the promised 12-month window.
Got a response from them yesterday that they have verified the information I provided and they have forwarded it to the concerned person. And today morning, I got the test invite.
Please update the register. Application Date - Sep 5, 2017.
