I would like to visit Canada on a visitor visa for work. I am curious if my history would create a problem in the visa application process. About 16 years back, I was deported from the US at the point of entry. This was under section 235(b)(1). It was primarily because they had found out that I had worked in the US while I was on a visit visa. Unfortunately, I wasnt told that I was also handed a permanent ban which prevented me from entering the US. I only found this out when I applied for the US visa last year. So bottom line, would my history be a cause for concern while applying for the Canadian visa?Will the Canadian authorities have the information of the deportation/life ban handed by the US authorities.
