Canada cannot win a trade war with the US. When we are on our knees he’s going to ask for Yukon, nwt and nunavut. Saying basically nobody lives there and we don’t need it. He can easily buy out northern Canadians by offering lots of money or citizenship and the other 39 million Canadians will reluctantly agree it’s the best compromise.
He knows climate change is real and it makes the north more and more viable every day due to its resources and shipping route.
Another obvious hint at this was traitor Danielle Smith suggesting US military bases in the north just last week.
It’s actually the opposite; US shale oil is very high quality in terms of purity. The problem is that their refineries are built around the idea of processing lower quality crude because the by-product is used in manufacturing other goods.
Canada’s oil sands produces the crude they need to make money off that by-product.

Which is great for us, because it means export tariffs would have an outsized impact on their secondary petrochem product prices.
