Thanks for the reply. Our AOR date was 21st August. This is the first update in our profile.I am sorry to hear this. Don't worry everything will be fine next time around.
You will need to mention your Application number starting with E and UCI number too in the new application. The rejection will have no affect on your subsequent application so quit worrying, and make sure you don't repeat such silly mistakes again. Please go through the requirements and make an application accordingly. You do not need to mention anything separately in LOE.
By the way, which stage your application was, and what was your AOR?
All the best.
If we get ITA, do we need to answer yes to the below questions in eAPR:
1. Has<applicant> been refused refugee status, or an immigrant or permanent resident visa (including a Certificat de sélection du Québec (CSQ) or application to the Provincial nominee Program) or visitor or temporary resident visa, to Canada or any other country?
2. Has <applicant> ever been refused a visa or permit, denied entry or ordered to leave Canada or any other country?
