I have almost the same timeline as yours but Mississauga office. I don't know why Jan and Feb applicants penalized? Applicants from Mar and Apr have the oath letters in their hands. And we are still waiting for Test invite.
BTW, i called IRCC today. They said your applications cleared all the required verification and move to next step and that is " Citizenship Test". All i have to do is to wait.
Also, i told them that i will be travelling in Sept that is important i can't move my flight, so they added an extra line in my case that please don't schedule Test or Oath during these days. My Question here: Does it effect my application? Please comment
