Is all 806 days and 674 days happening in last 5 years ? Not travelled in last 4 or 5 years ? Then you should be good.No, total calendar day presence was 674 before becoming PR so counted 337 as 0.5 days. So, my Question is during the above mentioned time she was on Visitor visa and Super Visa. Is it considered as a temporary resident and whether this time spent in Canada can be used for total physical presence or not?
Another check is any waiting periods between visa extensions etc. I guess it is a valid stay once visa gets approved. Check in that perspective.
And then give a call to IRCC to understand better.
