I think Michael's right that the outer space treaty left it a little bit open to interpretation. It is prohibited to appropriate in space. If you ask any country where other countries or companies have come in to take their natural resources, they will say that is appropriation.
There are debates as to whether or not the Artemis accords themselves are perhaps—some countries would say—a violation of the outer space treaty. The U.S. has simply said that it is their interpretation of the treaty that space mining is lawful and will take place. Any country that has signed on to the Artemis accords has thereby agreed with that definition, which includes Canada. It includes Australia. Australia is one of just three countries that have signed both the Artemis accords and also the 1979 moon agreement, in which it said that no entity can own any part of the moon, and that, if space mining is about to take place, we need to have an international regulatory regime in place.
There are discussions ongoing at the committee on peaceful uses of outer space. There are three or four different regimes, and China and Russia have their own alternative regimes. We just don't quite know what the outcome is going to be.
