Hi, we were in a similar situation, we first submitted our application in December, saying that we need to submit our notice of assessment. I had submitted my T1 general instead of notice of assessment, so I resent the application with NoA attached . Did they highlight notice of assessment or letter of employment? For me, both were mentioned in one sentence but notice of assessment was highlighted . Since they had updated the checklist in February, they just mention in the letter , but that’s not the reason for sending back the application. Also did they highlight the police certificate part ? If they’ve not highlighted then you need not worry, they just mention it as precautionary measures. Just look for the points they’ve highlighted, the ones highlighted are the ones missing . Also when you resubmit, check if any form has been updated recently , if yes, it’s better to send updated forms . Also about your question regarding implied status , my husband was on a work permit that was tied to his employer, which expired on December 2018. Since we had applied for open work permit, he was no longer on implied status and had to stop working after December. If your partner was working on OWP, better to call cic and check about implied status . When our application was returned to us, he was out of status , so I paid restoration of status fees too and marked the same on the form. Was your owp application returned too ?
