Canada is done waiting for Washington.
President Trump's 50% duties on certain Canadian goods came after trade negotiations between the two neighbors collapsed. Canada's answer is a new round of tariffs on U.S. products.
A tariff, or duty, is essentially a tax levied on goods as they pass across a border.
In trade terminology, this is known as a countermeasure, which is simply a formal term for a response. When one country taxes another's goods, the second country often answers with taxes of its own, and the cycle can keep going until someone changes course.
The timing matters too. An announcement at 11 a.m. ET falls during trading hours, so investors will have a chance to respond right away.
LeBlanc made no effort to hide where Canada stands.
"Our preference was not to do that," he said. "Our preference was to find a deal that benefits both countries."
In other words, tariffs are a fallback, not a first choice. The outcome he wants is still a deal that works for both sides.
He still believes that deal is possible. But he also made clear that Canada is not going to sit around waiting for the U.S. to make the next move.

"We still believe that's possible. But in the meantime, we're not waiting by the phone."
Trade officials use this kind of language all the time: keep talking, but keep the tariffs moving. It is how countries show they are serious without slamming the door.
The bill for those tariffs always lands somewhere. A company can swallow the cost, hand it to customers, or squeeze it out of its own profits.
The same logic applies on both sides of the border. Canadian shoppers could see higher prices on U.S. goods, and American companies selling into Canada could feel the pressure in their sales.
Tariffs also travel through supply chains. A business that buys supplies from the other country faces a higher bill, and that extra cost can move down the line before anyone sees the final price.
The first product to feel the hit is rarely the last one.
At 50%, the American duties are not a small nudge. They are the kind of number that can change a company's math.
Uncertainty is a big deal for businesses too. When trade rules change quickly, companies may hold off on hiring, buying equipment, or expanding across the border until they know what the new rules will cost.
That kind of uncertainty is hard to put a number on. It is not just the tariffs themselves, but the question of where they stop.
The bigger question for investors is what this fight does to a trading relationship that affects a lot of businesses. The U.S. and Canada are major trading partners, and companies on both sides have built their operations around easy cross-border trade.
New tariffs add friction to that setup. Costs go up, profits get squeezed, and the uncertainty can ripple through stock prices.
Tuesday's announcement will show exactly what Canada's countermove looks like. The details will matter, but the direction is already clear: Canada is not backing down.
The effects will unfold over time, in prices and in the profits of companies you may already own. For investors, what matters is what comes after the announcement.
If the two sides calm down, this becomes a bump in the road. If they keep pushing, the costs will spread, and your portfolio can feel it.
The history of trade disputes shows that both sides often escalate before a resolution. Canada's move is a clear signal that it will defend its interests, but it has also left the door open for talks. The coming days will reveal whether the two governments can find common ground or whether this cycle of tariffs will continue to deepen.
