In trade you can put these columns.
Things the USA needs. Oil, Energy, Potash, minerals, wood, water.....
And we, once we diversify, stop discounting them. Without other compensation.
And yes, our food supply chain can be called a security issue and limit foreign entry. There is lots we do let in unfettered. There is no reason we have to let it all in.
And we are increasing the defense spending. A lot. Look it up. This time I don't think its just talk. It's going to happen.
I do see the big picture. And it involves being less reliant on US trade.
I don't think you understand what a two-sided ledger is in regards to current U.S.-Canada trade. You would have to have honest recognition that Canada derives certain advantages beyond what a truly free market would grant. Some members keep referring to U.S. and Canada as a free trade relationship. It's fairly free in certain industries, but it is not free trade no matter what they called NAFTA. More truthfully, they ditched the term "free trade" since it was just creative marketing.
In regards to all the commodities that Canada can sell the world, I've previously discussed this. Oil is your best bet. The reason is that your government has been constraining the production and distribution of oil for quite some time. That's the only reason. It's not some silly idea that you were giving it to the U.S. at a discount. You still have to transport the oil over the Rockies, get it on to ships and likely ship it almost 5,000 nautical miles. The other commodity that could provide a boost is gold. This is being driven by high global prices and the relatively low transportation costs for gold.
Potash is an excellent example of the limits of selling and distributing fungible commodities. Potash is under US$400 a metric ton. It takes some imagination to wrap one's brain around the price to volume ratio. Let's just say it's expensive to transport. That seems fair.
There's thousands of train cars of the stuff heading down from Saskatchewan to the U.S. Why? Because it's by far the easiest and most accessible market (relatively low transport costs). It's not because you are giving potash away at a discount, but rather shipping it anywhere else is costly.
Now the Chinese are big potash consumers. Perhaps Carney signs the Sino-Canadian Reliability Agreement for Potash (SCRAP). (You have to allow me to lighten up a dry trade discussion a bit.) Great news! China buys more of its potash from Canada. However, you have to realize all global commodity markets are in a general state of equilibrium. If China buys more from Canada, they now buy less potash from Russia, Belarus and Laos (an expanding potash producer).
So what happens now? Russia is off the table for the time being. However, Belarus and Laos are looking to sell their excess potash that China no longer wants. They go to the U.S., Brazil, India, etc. and say I got a deal for you on potash. I think you see the problem. Canada is shipping more potash across the Pacific to China. Laos is likely shipping more potash back the other way to the U.S. and South America. The disruption to the market equilibrium is not exactly expanding potash sales for Canada or any other country, but rather driving up transportation costs for every producer.
