I could not, of course, explain the matter without knowing how they keep their records. I know that on the whole, our records can be taken as being accurate. Supposing, however, a man is coming in from the United States, travelling on a train. He has a grip with him. The immigration officer sees him, and the man says: "I am going up to Canada only for a visit." As a matter of fact, he is coming into Canada permanently. He is simply lying, and he stays in Canada. That man is not recorded, because he did not tell the truth to our officer. As regards all persons coming into Canada from the United States or abroad, if they will tell the truth when they are coming in, their statements are _ recorded accurately, and we know exactly the number of immigrants. I use the word "immigrant" as applying to a person coming to Canada for the first time to stay in Canada, and our figures as regards the number of immigrants are, on the whole, accurate. There may be a number who slip past our officers and who continue to stay in Canada, whom we do not catch at all. There may be some who state that they are coming in to stay, who do not stay, but who leave Canada within a short period, and in that respect, our figures will be inaccurate. These things cannot be controlled.
