I asked the officer why I am going through this even though I am a Canadian citizen now. He said because my file is associated with a refugee status previously and that I have to contact Immigration.
Has anyone gone through this? I was a refugee before but I thought it doesn't matter once you are a Canadian citizen.
It is sad and embarrassing that I am being treated with respect as a visitor in other countries and as a "Canadian citizen" be humiliated and asked to step aside when I return to Canada!
There are scores of anecdotal reports in this forum of similar experience. While it appears that former refugees are more often the subject of background flags/alerts than other naturalized citizens, this is not limited to former refugees. The reasons for such alerts vary widely, depending on the individual and their particular background, their history, and this includes their particular immigration to Canada history. But it can also be related to more recent information, concerns, including recent travel.
There is no reason to be embarrassed about being referred to Secondary questioning upon arrival in Canada, well unless there are reasons why the particular individual should be embarrassed.
There is no intent to punish, chastise, criticize, insult, offend, or "humiliate" travelers who are subject to additional examination past the PIL (Primary Inspection Line).
It can be inconvenient in terms of how long it takes, but you have not indicated how burdensome or imposing the additional questioning was.
As I noted, when and why this happens is very individual to the person traveling, but most of the reporting suggests that even though the Secondary questioning can occur repeatedly, even after several trips as a citizen, the scope of it tends to lessen and for most it eventually ceases even without making a complaint. Of course for those who Canadian authorities have identified cause for security or criminality concerns, obviously the scrutiny will continue. For obvious reasons. As in that's their job.
Some more or less legacy information likely lingers in some new citizen's GCMS records. Individuals can push, such as through their MP, to have related concerns noted resolved, or simply help facilitate officers to more quickly clear them during the border examination.
Some discrimination undoubtedly occurs. People eh. But generally CBSA officers have enough to do without going out of their way unnecessarily to question returning Canadian citizens without cause. Of course the individual citizen may very well know there is not any cause for concern about them, we all know ourselves. What law enforcement officers MUST act on, in contrast, is the information available to them.
Generally the better approach is to answer questions and demonstrate there is no reason for concern. Questions are not prosecution let alone persecution.
Beyond that, frankly, I'm not buying the portrayal of Secondary examinations at a Canadian Port-of-Entry as comparable to conditions which warrant flight from other countries to seek protection.
