No, the visitor record is to extend the visit visa if you stay beyond 6 months. It makes sure I was never out of status in Canada before I became a PR.
In my case, it was important to provide proof that I applied to extend my visitor status and that it was approved. This shows that I was never out of status during the eligibility period. The eCOPR only confirms my entry date into Canada but does not verify whether I was on maintained status. Also, with IRCC, I believe it's best to provide as much valid proof as possible.
I mean they can easily confirm all of this info with CBSA but seems like if you use any visitor days in your physical presence calculation, the onus is on the applicant to prove they were actually in Canada. IRCC doesn't bother to do any verification on its own.
