PR card renewal physical presence day calculation

[HAPPYFAN]

Hi GUYS !! I NEED YOUR HELP

I am currently helping my mom renewing her PR card. However she traveled abroad SO MANY times in the last 5 years, and she lost track of her own travel record in the year of 2015 and 2016. And therefore I can not calculate her physical presence days at this point.
Any suggestions would be much much appreciated!

Thank you all in advance!

Saw your post on another thread too.
For your mom's PR renewal, sadly there' no other way, that I know of.
If she had enough time in Canada to meet the RO for which you have definite proof.
and then for the rest, type a detailed letter to IRCC, and in the form, put the tentative dates.
Well, that's my opinion. You may wait / seek out other's advise as well.

You may call IRCC and ask them what to do ?
