We sent our app in without having done a medical exam, and without my police certificate. We sent those in later, before CIC requested them, and our process was not delayed.
We sent in just the sponsorship portion of the app (when you start reading through the Québec stuff, it's pretty easy to get confused) in August of 2012 without the PR portion of the app. I hadn't found this forum yet, and we thought that was how you applied from within Québec. I received a call from a woman at CIC stating that my app was incomplete and telling me to submit the rest of it. She provided a mailing address and a name for the person to whose attention we should mail the rest of the app. Our application was noted as "received" on October 23, after the PR portion was received and matched up with the sponsorship app we had already sent. So I don't think you can start the sponsorship application without the PR application. Our sponsorship app should have been returned to us as incomplete, but the lady at CIC helped out by holding it until we sent the remainder of the PR app.
