You gave up American citizenship before applying? If so why then? And why at all? Do you have another nationality or are you stateless until you get Canadian citizenship?
If you applied 11 months ago, you applied when a ton of other people applied because a swath of people who were previously ineligible (all the PR people from October 2013 - October 2014) became eligible due to C-6 coming into effect that month regarding residency obligations.
This is wrong. Processing times in 2015 to most of 2017 were lower (4-7 months) because of C-24 and the changes to residency requirements from 3 to 4 years. Officers making more decisions on citizenship apps came into effect with C-6 only earlier this year (delayed rule). Yet backlog is increasing anyways. Looking at the October - December 2017 times people are going 9-12+ months now from app received to oath. As another poster mentioned, there's no guarantee of an app being prior to 12 months, it's entirely based on a multitude of factors, ranging from staffing, to complexity of the application, backgrounds, and so on.
I was impatient as well when I sat there almost half my application waiting between the test and oath, but reality is, you have to be patient, regardless of how hard it is. I simply stopped looking after a while, including on these forums, and went along my daily routine until I got the invite.
