if one has traveled to Australia Nov,2008 and returned in July,2009..now got new book of passport ,old one has expired and its not attached with new one...now my question is if i apply for Canada student visa ,is it mandatory to mention in student application form about past travel history..i am just asking because i will have to get Police Clarence report from there...which takes lot of time...i want to ask if that can be let it out blabk or not declaring about that...would that create any problem?
