Thank you Scylla for the info, my situation was, i applied for a Canadian tourist visa online last DEC.2015 and i receive the visa refusal result in Jan.2016, the response was,
the information in the travel and identity documents,
the reason for travel to Canada
the persons contact in Canada
the persons ties to country of res.
the persons ability to pay for the trip
whether the person is likely to respect of his admission to Canada
whether the person is inadmissible to Canada
whether the person would likely to leave Canada at the end of his authorized stay
other reason (x) you did not declare your us visa refusal
i have uploaded some real property under my name,i uploaded my previous passport have traveled to Malaysia, Singapore, Libya and Saudi. i uploaded also my bank account in the Philippines and bank account here in Saudi, i made a mistake which i consider more of an oversight, i was supposed to declare whether or not i have been denied a visa to other country. i indicated no, i only read and understood the question was only limited to that of Canada.
