You have to inform CIC of the whole situation and explain why you had been refused, why you were not aware of their refusal and why you had responded "no" instead of "yes".Hello guys,
please tell me what will be threat for me in my situation:
My lawyer had applied for Canada visit visa once this year and He now informed me that I had been refused before my AOR (June, 2018). I didn’t know that I had been refused when submitting my EE application so I selected ‘No’ in answering to “Has XXX been refused visitor or temporary resident visa to Canada?”, albeit I have informed IRCC of my UCI number through my Express Entry profile before my submission. It means that I informed them that I had applied for tourist visa but I did not inform them that I had been refused because of lack of responsibility of my lawyer who is telling me after 10 months of my tourist rejection. Last night I made a CSE and told to IRCC that I did mistake in answering this question although I provided my UCI number from my tourist visa. I didn’t explain the reason that the lawyer was to blame and I made it general and somehow vague. My BC in my profile is “we are processing …” which has changed recently, I think during ten recent days. I have neither called IRCC nor ordered note so far. What will happen for me? Is there any similar experience for you or your friends?
Now you have to explain to me why you had not been aware of the refusal ? When one applies for a visa, independently or through a lawyer, they wait for the outcome so I'm a bit confused as to why this isn't the case.
As long as you didn't conceal that fact knowingly, you shouldn't have issues. But you have to immediately submit a CSE and explain the whole situation, otherwise you're risking a refusal with a ban and the clock is ticking.
