Good day everyone. I got an ITA on Oct 18..I have been filling the online form and there is a space they asked if one has been refused visa or permit into Canada or any other country in the past.My wife was denied UK student visa in 2007 due to the blurring of picture on her Secondary school certificate.My dilemma is this,if I pick yes,they might ask us to provide letter of reason for refusal which we can't lay our hands on.If I say no and they eventually find out,they might count it as misinterpretation. I am confused on what to do. I want to play safe.what can I do in this kind of situation? Do they actually verify this kind of information if If I say no.Thanks
