Would it not be better to maintain the compulsory provision, that is, make it obligatory on the parties to manufacture in Canada, but in the case of such an accident as the minister has mentioned, fire, deluge, or some act of that kind, the commissioner should have nower to extend the period? But the principle is what I am after. I think we ought to retain as far as possible the principle of obligatory manufacture in Canada, making it imperative or obligatory upon the person taking out the patent to manufacture in Canada. If we remove that feature and give to the commissioner discretionary powers such as my hon. friend has just intimated, it is in my estimation altogether, too extensive a power to delegate to an official. Let it be the reverse. I think the principle of the old act is the better. However, if the minister wishes to proceed with the reading of the present section, we can probably bring these points out as we proceed.
