Canada aligns with US EPA27 truck emission rules for now: what fleets buying 2027 trucks should know
If your fleet plans to buy new medium- or heavy-duty trucks in 2027, Ottawa has just removed a big source of uncertainty. An interim order published in the Canada Gazette on October 31 keeps Canada's truck and engine emission rules lined up with the US Environmental Protection Agency (EPA) while the US finishes changing its own 2027 rules. Here is what changed, what it means for truck prices, and how to plan your replacements.
What happened
Canada has historically adopted the US EPA's emission rules for trucks built and sold here. When the EPA rolled back some of its model year 2027 requirements, Environment and Climate Change Canada (ECCC) was left with a rule it could not enforce, Truck News reports.
That mismatch put the supply of new trucks at risk. Kevin Disher, executive director of the Canadian Truck Dealers Association, warned on Parliament Hill that without timely action, "the availability and the importation of new trucks in Canada could face significant disruptions as early as Jan. 1, 2027." He said manufacturers had told dealers they would not open Canadian order books for 2027 models without more regulatory certainty.
The fix is an interim order made by the Minister of the Environment on October 13 and approved by cabinet on October 23. According to the approval order, it:
- keeps Canada's air pollutant standards for on-road vehicles and engines aligned with the US EPA, and updates references to US regulations;
- suspends the greenhouse gas (GHG) emission standards for trailers;
- keeps Canada aligned with US vehicle classifications for passenger cars and light trucks.
The order lasts up to one year from October 13, 2026, or ends sooner if it is repealed or the regulations are amended. The government says it is needed "given the integrated nature of the North American market."
What it does not change
This is not a rollback of Canada's heavy-duty rules. Truck makers selling in Canada must still meet the 2027 rules or pay a per-vehicle penalty on non-compliant trucks sold after January 1, 2027, Truck News says. Canada is also not changing its heavy-duty truck and engine GHG standards, finalizing revised useful-life or warranty provisions, or setting a separate California alignment policy for at least a year.
The final picture is still open. The US EPA has not issued its final rule on the proposal it put forward in July, which covers useful life, warranty, non-compliance penalties and diesel exhaust fluid (SCR) inducements. Disher expects ECCC to issue a final order sometime in December.
What it means for truck prices
Dealers are already taking 2027 orders, according to Disher. Fleets will likely see two kinds of engines on offer:
- EPA27-compliant engines, expected to add roughly US$10,000 to $16,000 per truck.
- Legacy engines sold with a non-compliance penalty, with penalties expected in the $7,000 to $8,000 range.
Disher says almost all manufacturers are expected to offer legacy engines with a penalty until at least fall 2027, though "nothing is written in stone at this point." Either way, a new 2027 truck is likely to cost more than a 2026 truck did. That lands on top of other cost pressure, like the new tariffs on cross-border goods and diesel near $2.60 a litre in Ontario.
Checklist: planning truck purchases for 2027
- Ask your dealer both prices. Get quotes for a compliant engine and a legacy engine with penalty, and ask how warranty and service terms differ.
- Watch for December. The expected final order from ECCC and the final US EPA rule could change warranty, useful-life and inducement details. Get the latest before signing.
- Check build dates. The Canadian order sets different standards for 2027 engines depending on whether their manufacture is completed before or after December 20, 2026. Confirm with your dealer which applies to the truck you are buying.
- Trailers. Trailer GHG standards stay suspended under the order, so trailer buyers have one less rule to plan around this year.
- Rank your current trucks. Use real mileage and usage data to decide which units truly need replacing and which can run another year.
How GPS data helps you stretch the fleet
When new trucks cost more, getting the most out of the ones you have matters. Hardwired GPS fleet tracking shows the actual kilometres each truck runs, how long it idles and where it sits unused. That helps you:
- rotate high-mileage trucks onto lighter routes so they last longer;
- spot underused trucks you can reassign instead of buying another unit;
- schedule maintenance by real kilometres, which helps older trucks stay reliable through winter.
The rules for 2027 trucks will keep shifting until December at least. Knowing exactly how your current fleet is used puts you in a better spot to decide what to buy and when.
