I am here to get an answer for my Father. He's lived in Canada for many years without a status. Now he would like to return to our home country. He wants to turn himself to inmigration and voluntarily leave the country. Most likely he'll be detained, but for how long will he be detained? If he has his flight ticket ready, will they just let him go? Or will they detain him for a long period of time? Your answers and information would be greatly appreciated.
