Definitely raise a webform once the AOR comes in with the updated calculator. Since your application was not returned, I believe you should keep the application date the same when you applied. Don't quote me on it though, please double check. Luckily from what you said, you still meet the 1095 day requirement. Had the calculator gave you less than that would've resulted in a returned application.
Well, you don't understand. Even if I tried filling out a completely fresh physical presence calculator, it will still be exactly the same as before. Let me elaborate. In the year 2017 (which falls under my 5 year eligibility period), I traveled to France from my home country Denmark. I had never ever been to Canada at that point in time. So, when the form asks me:
Date you Left Canada : what am I supposed to write here?
I didn't leave Canada, because I wasn't in Canada. I left Denmark.
If I had stayed in France for a continuous period of 183 days or more, then a different section in the calculator would capture this fact, and I would have to produce a PCC from France. Even in this case, I still couldn't fill the section that asks:
Date you Left Canada -
Date you returned to Canada
because this would still be inapplicable in my case.
