I get the hint, but I'd rather be prepared than scramble last minute to produce documents that are not in the checklist. E.g., if I live with family (and don't have a lease or a mortgage in my name), would that matter? Or does CIC look at CBSA records to estimate physical presence residency (which I believe the applicant can authorize them to access and/or provide the records obtained from CBSA in addition to the copy of the online physical presence calculator)Again, you're underestimating the intelligence of the IRCC officials.
If you provide exactly the information they need, they will process your application smoothly. If you provide more information than requested, the officer will take longer to review your file.
Hope that answers your question.
