According to the former and future US President, Canada's water is like a 'very large faucet' that one could turn on, say, to help California in a drought, or any other Pacific Northwest state that might need it. According to scientists, it's ... not like that at all. But still, Canada has water. And increasingly, the United States needs it.

Does Trump actually intend to ask for, buy or even take Canadian water? Would it even be possible if he wanted to? What do Canadians need to know about their abundant natural resource as the climate crisis makes it scarcer around the world? How worried should we be about Canadian water?
