If an employer were here, I would ask the same question and so would you: “Look, you went through this whole process and took six months to get a truck driver here, and suddenly he was to appear and never showed up. What do you do to track him down?” And the employer would say, “How much time and money do I have? I don't know. If he was coming here, we interviewed him from Qatar, from Dubai, or wherever, and he was supposed to be here. He's not. Human Resources allowed me four truck drivers. He's not here. I have a list of 20 others. I'm going to contact the next person and get him here.”
The question then becomes that maybe that should also be an issue, not just an isolated one of immigration but one for Human Resources when they approve the employer. If these people do not attend or if someone is identified, here's what your recourse should be. And I think having notification of immigration, last known address, etc., would be incentives for the employer to get back and try to locate that person, because there might have been a miscommunication, as happens in Winnipeg sometimes, or maybe the person is genuinely not a truck driver but is here for some nefarious purpose. I think that should also be dealt with by our friends over at Human Resources.
