I also have the exact same problem. I am an applicant from Dollard-Des-Ormeaux (city in Greater Montreal). They physically received our application on October 25, 2017 and sent us the AOR on November 27. They started processing my application on January 16, 2018 and sent me finger prints application on March 16. I submitted my finger prints on March 20, and heard nothing from them since then.
I called, and wrote to them several times, but all what they say is that I am still within the normal processing times and that I have to wait.
Honestly, I almost gave up, and will wait until October 25, 2018 to file a complaint. They won't have any excuse around that time.
Anyways, I totally understand that the citizenship is a privilege and not a right, but I am really frustrated too.
