That's how an
analogy works.
They don't have a 'right' to reject anytime, they have a 'right' to select which they do exercise. The applicant has a 'duty' to present the required documentation(s) at all points throughout the process. And if the documentation is in order and PPR has been issued, the applicant has a 'right' to receive COPR and be admitted into Canada and CBSA has a 'right' to verify any and all documentation(s) required before admitting anyone into Canada. The simple reply is, they cannot reject your application between PPR and COPR unless they know that you have falsified information to get the said PPR. Even in that case, they cannot 'arbitrarily' reject your application - they still need to give you a fair chance to clarify things at your end. So there are more chances of being turned back at the Port of Entry (which are fairly minimal in themselves) than being refused between PPR and COPR (infinitesimal chances , non zero probability which is analogous NOT equivalent to the chances of gravity being repulsive in some corner of the Universe).
For someone who doesn't like the Canadian government's reliance on IELTS and English language, I expect you to not get the difference between analogy and equivalence hence had to spell it out.
Have a good day!
enjoyed it !
