But I did declare ALL of my day trips to the US, with exact dates, eight of them total in the last four years. The officer just didn't want take my word for it. He said he wanted to make sure I don't fall short since I've applied with only 1462 days, but I think that was just a pretext. He didn't like me from the start. It was obvious just by the way he was grilling me about my old passport and my distant past, pre-PR time; questions that had nothing to do with the requirements for citizenship, really.
Like I said earlier, my friend at work she applied at the same office a year and half ago. They approved her on the spot. No need for CBSA report. And she had more than just day trips to the US. She had two-week long absences. But no problem in her case. They just accepted her declaration.
That's the epitome of unprofessionalism -- when you don't have a consistent way of handling cases, and the process depends on the whim of the adjudicating officers.
