Can you resend exactly what you sent them? I'll have another look to make sure that something wasn't overlooked. Then, I would either call CIC and/or MP.
It sounds like they've zeroed-in on a specific problem in the form. I seem to recall discussion regarding dates. What we did (and what I generally share with others) is it's far better to have overlap then any kind of perceived gap in time.
Example: you move from one place to another at the end of May 2017. It's better to say that you were at that place from whatever date until 2017-06. Then the next place is 2017-06 to whenever.
Even though you have a new place to live, you also have the old place to live (and receive mail at). When they look at these forms, they don't think: "oh they mean 2017-05-31 23:59:59". To them, it can mean "2017-05-01 00:00:00". Then the question becomes: where were you from "2017-05-01 00:00:01 - 2017-05-31 23:59:59"? You can have a lot go on in 31 days.. like jail. Not at all implying that's the case here, but that's exactly the kind of thing CIC is looking for WRT gaps.
The forms are ambiguous, and I think they should have documented examples like I suggested above. Or, for the CIC double agents in the crowd, you should cite a link to this post. Remember to cite your sources
. The processing time reduction of ~60+ days can be achieved in probably 50% of cases or better, with better documentation.
That's the problem of using the month as the lowest common measurement.
