I have applied for spousal sponsorship visa. My wife is a Canadian Citizen. On form IMM 5669E, I have made a mistake by ticking the box in front of the statement: Have you been refused temporary resident visa to Canada or any other country. My problem is that I have been refused study visa to Australia before but while filling the application form I forgot to specify that. What should I do now ? I believe CIC would not know about this since the visa was refused by another country and not Canada. Please help. Does CIC gather this kind of data from other countries ? I assume they can not be searching the whole world to verify my details. Can anyone please shed some light. I will be highly grateful.
