Two weeks ago we wrote that two bills would land on the same morning. This is that morning. At 12:01 a.m. Eastern today, Canada's counter-tariffs took effect on C$27.6 billion of United States imports across more than 600 tariff lines. A few hours earlier, at midnight, the federal fuel excise tax holiday expired.
If you import anything from the United States, or move freight that does, today is not a news story. It is a pricing problem with a paperwork answer. Here is what actually changed, what is exempt, and what is still worth doing this week.
What Changed at 12:01 This Morning
Canada's countermeasures are a dollar-for-dollar response to the US Section 338 duties that took effect on August 22, and they are built to mirror rather than escalate. Each Canadian rate matches the corresponding American rate on the same class of goods, which is why the list runs at three tiers instead of one headline number.
The scale is the part worth sitting with. C$27.6 billion of trade, more than 600 tariff lines, and a list that reaches well past the symbolic categories into the industrial inputs Canadian companies actually buy. The full legal list is published by the Department of Finance and organised by HS code, which is the only way to know with certainty whether your product is on it.
The Three Rate Tiers
Look at the 15 and 25 percent tiers rather than the 50. Forklifts, agricultural machinery parts, appliance parts and industrial molds are not consumer symbolism, they are the equipment Canadian businesses use to make and move things. A warehouse replacing a forklift this quarter now pays more for it, which lands on the same operations already dealing with the tightest industrial space market in years.
Two Bills, One Morning
The second cost has nothing to do with trade policy. The federal fuel excise tax holiday ran from April 20 and expired last night. From today the tax is back at its full rate: 10 cents a litre on gasoline and 4 cents on diesel.
Four cents a litre sounds small until you multiply it. A tractor running 150,000 kilometres a year at 40 litres per 100 kilometres burns roughly 60,000 litres, so the excise change alone is about $2,400 per truck per year. That arrives on top of the diesel benchmark move we covered in The Cheap Freight Is Gone, and it is why fuel surcharge mechanisms are getting reopened this week rather than next quarter.
Three Things That Can Still Reduce Your Bill
Before you re-price everything, check whether the shipment is actually captured. Three routes matter, and all three are paperwork rather than argument.
- Goods in transit. Finance Canada states the countermeasures do not apply to US goods in transit to Canada on the day they come into force. Document departure, not just arrival.
- Origin under CUSMA. The measures target goods of US origin. Correct origin determination decides capture, and many importers have never formally verified it.
- Remission and drawback. Existing frameworks for requesting remission continue to apply, and drawback may fit where imported goods are later exported.
- The complete product list by HS code, published by Finance Canada.
- CBSA customs notices, where administration and reporting requirements are published.
- CARM, where the duties are assessed and paid, and where a registration gap becomes expensive fast.
What This Does to Freight, Not Just to Prices
Tariffs change trade flows before they change prices, and trade flows are what fill trucks. Three effects tend to show up within weeks.
Worth noting what has not changed: the underlying trade agreement. The CUSMA joint review is still the mechanism that decides the medium term, and today's measures sit on top of it rather than replacing it.
"A tariff list is not a policy debate when you are the importer of record. It is a number your broker enters, on a date you cannot move."

When exactly did the counter-tariffs take effect?
12:01 a.m. Eastern on September 8, 2026, covering C$27.6 billion of US imports across more than 600 tariff lines at 15, 25 and 50 percent, with each rate matched to the corresponding US tariff on the same class of goods.
Are goods already in transit caught?
No. Finance Canada states the countermeasures do not apply to US goods in transit to Canada on the day they come into force. Document departure carefully, because proving transit status falls to the importer.
What is on the 50 percent tier?
Steel and aluminum, dairy, pulp, paper and plywood, electronics, clothing, plastics and rubber articles, cosmetics and sports equipment. The 25 percent tier covers wood and lumber, household metal articles, appliance parts, carpets, cutlery and cheeses. The 15 percent tier includes forklifts, agricultural machinery parts, air conditioners and industrial molds.
Is the fuel tax change part of the tariffs?
No. The federal fuel excise tax holiday began April 20 and expired September 7, so the tax returned today at 10 cents a litre on gasoline and 4 cents on diesel. Two unrelated increases simply landed on the same morning.
Can an importer get relief?
Existing remission frameworks continue to apply, CBSA publishes administration details through customs notices, and duty drawback may fit where imported goods are later exported. Relief is case by case and document-driven, so start with your broker rather than assuming an exemption.
Does CUSMA qualification change anything?
Origin decides capture, since the measures target goods of US origin. Establishing and documenting origin correctly is now a cost decision rather than a filing formality, and many importers have never formally verified their position.
