IRP apportioned plates explained

One plate, one registration document, and a fee split across every jurisdiction you actually drove in.

Treadstone Associates · Updated 2026

Key takeaways

  • • IRP distributes commercial vehicle registration fees across the provinces and states you travel in, so one plate and one registration document cover all of them.
  • • Ontario says carriers travelling outside the province should register vehicles over 11,793 kg gross weight or with three or more axles.
  • • Fees are prorated by the percentage of your distance driven in each jurisdiction; the reporting period is 1 July to 30 June.
  • • The cab card is issued in paper and electronic formats and must be produced on request by law enforcement or the IRP Registrar.

The short answer

The International Registration Plan is, in ServiceOntario’s description, an agreement between certain Canadian provinces and US states that distributes commercial vehicle registration fees based on the total distance travelled in each place. It allows vehicles to travel between participating provinces and states with one licence plate and registration document. Without it, you buy trip permits every time you leave the province.

Who should register: all carriers who plan to travel outside of Ontario, if they operate vehicles that have gross weights over 11,793 kg or three or more axles. Ontario adds a useful rule of thumb — if you plan to make more than 12 trips outside Ontario, it usually costs less to register in the IRP than to buy single trip permits.

The cab card

The cab card is the registration document that proves the apportionment. Ontario issues cab cards in both paper and electronic formats, and both are accepted by all IRP jurisdictions in Canada and the USA. You must produce a valid and legible cab card when requested by law enforcement or the International Registration Plan Registrar.

If you use an electronic cab card, Ontario’s guidance is practical: the image must be accessible by computer, tablet, smart phone or other device; save it as a PDF so you can open it without wireless or mobile service; and carry a paper copy as backup in case of no signal or a device failure. Fleets that went paperless and skipped the backup step learn this at a scale.

How the fee is actually calculated

Two different rules apply depending on whether you have travel history. When you first join the IRP, or if your fleet did not travel in the last reporting year, your registration fees are divided among all participating IRP jurisdictions, split using the average distance travelled in each location by other Ontario-registered carriers — Ontario’s average per vehicle distance chart.

After the first year, fees are calculated from the distance you travel in each IRP jurisdiction and the annual registration fees in those locations: you pay a prorated percentage of each jurisdiction’s annual fee according to the share of your total distance driven there. Ontario’s own worked illustration is 40 per cent of distance in Ontario and 60 per cent in New York, producing 40 per cent of Ontario’s annual registration fee and 60 per cent of New York’s.

Two cautions. Some jurisdictions charge additional fees separate from IRP fees, so check the ones on your lanes. And if you do not travel out of the province at all, you pay 100 per cent of Ontario’s registration fees, and carriers who do not travel out of province over a long period may not be able to renew in the IRP.

The reporting period is not the calendar year

This trips up new registrants every year. The IRP distance reporting period runs from 1 July to 30 June, and that period is what the ministry uses to calculate your fees at renewal. If your fleet’s renewal date is on or before 1 September, you may use the 1 July to 30 June period from the previous year.

The practical consequence is that your renewal fee is decided by driving you did months earlier. A fleet that changed its lane mix in March sees the effect on the following renewal, not this one — which is worth knowing before you argue with the invoice.

Adding a vehicle mid-year

Ontario states that when you add a vehicle, IRP fees will be based on the purchase price of the vehicle — the full amount paid by the current owner to the seller to obtain ownership, including documentation, accessories, service, finance charges, any other charges incurred to complete the sale, and the cost of capital modifications made within 30 days of the acquisition date. It does not include retail sales tax or HST, and a trade-in cannot be used to reduce the taxable purchase price.

Keep the bill of sale and the modification invoices together. The 30-day window on capital modifications is short, and reconstructing which upfit was invoiced when is a bad use of a Friday.

Where IRP is administered in Ontario

Since 3 March 2025 all IRP services are provided by ServiceOntario. Applications can be completed online through the IRP online services system, or by email to the IRP processing address, and in-person services are by appointment only at selected ServiceOntario locations after the application has been processed.

The workflow matters for planning: after you complete a transaction online and provide the supporting documents, the centralised processing team reviews it, and once processed you receive a payment notice and can book an appointment to pick up your validation or permits. Ontario also warns that you cannot make changes online once the system generates an invoice and that a vehicle never previously registered in Ontario must be registered at ServiceOntario before an IRP application is submitted.

Worked example: adding a tenth truck to a Barrie fleet in March

The fleet renewed in September using distance from the previous 1 July to 30 June period. In March it buys a used tractor for a Toronto–Buffalo lane, with a new APU fitted three weeks after purchase.

Three things follow from the rules above. The IRP fee for the added vehicle is based on the purchase price including the APU, because the capital modification was made within 30 days of acquisition, and excluding HST. The vehicle must exist in Ontario’s registration records before the IRP application goes in. And the New York share of the fleet’s fees will not reflect this new lane until the next reporting period is used at renewal.

Set the distance capture up for the new unit on day one. Its 1 July to 30 June record is what the following renewal is priced from, and there is no way to reconstruct a jurisdiction split from a fuel card statement alone.

Tow trucks have their own rule

Ontario addresses towing specifically. If you operate a tow truck to pick up vehicles outside Ontario, you must register for IRP or purchase single trip permits. Where the tow truck has a flatbed carrying the entire weight of the towed vehicle, register using the combined gross weight of the tow truck and the heaviest vehicle you plan to tow; where it carries only part of the weight and one axle of the towed vehicle rests on the highway, register using the gross weight of the tow truck alone.

The data behind IRP is the data behind IFTA

Both programmes are priced off distance by jurisdiction. IFTA needs it to apportion fuel tax; IRP needs it to apportion registration fees. Ontario’s fuel tax pages point carriers at IRP for the same reason: they describe all interjurisdictional carrier vehicles weighing more than 11,793 kg as needing both.

Build the distance record once, per vehicle, with jurisdiction boundaries captured automatically, and both filings become extracts rather than projects. The reporting periods differ — IFTA runs on calendar quarters, IRP on 1 July to 30 June — so the underlying data has to be dated and queryable, not summarised into quarterly totals and discarded.

Common questions

Is IRP the same as IFTA?

No. IRP apportions registration fees; IFTA apportions motor fuel taxes. Most interjurisdictional carriers need both.

Do I need IRP if I never leave Ontario?

No. IRP is for carriers who plan to travel outside of Ontario. A purely intra-provincial fleet registers normally.

Is an electronic cab card enough at roadside?

Ontario accepts both formats, but advises you carry a paper copy as backup for areas without service or a device failure.

What if I only make a few out-of-province trips a year?

Trip permits may be cheaper. Ontario’s guidance is that more than 12 trips outside Ontario usually makes registration the cheaper option.
