This is a hypothetical question about China's attack on Taiwan: How would it affect Canada? First of all, I think that if we see the like-minded countries in the world as a body, as a family, you probably don't want the values you stand for to be challenged. If you ask this question, you could also ask this question: If Ukraine caved in to Putin, what would happen in Canada?
On the first side, it doesn't seem to cause any change in your life, but I think that's the thin end of the wedge. It can come to you because it is very clear that China's intention is not only Taiwan. If China wants to only deal with Taiwan, they don't need to prepare missiles, with thousands of them deployed on the east and west coasts. With all that range, they can shoot missiles well over Taiwan and reach somewhere else in the world, including your territory. They will not stop at Taiwan.
It is a challenge to the international rule of law; the rules-based international order is what they challenge. You probably don't want that, especially now that we are talking about a geopolitical reality that these countries are not acting alone. They are aligned with their peers. China is working with Russia. In the Ukraine theatre, there's Russia, North Korea, Iran. Now they call it the new axis of evil. There are things like that, so we should not single out any part of the world, especially when China's intention is so well known, and they are trying to dominate all the international organizations and have their way through the international community. You don't want to see that happen. It's a very direct impact on Canada.
