Is a CVOR number the same as an NSC number?

For a carrier whose trucks are plated in Ontario, the CVOR certificate is its safety fitness certificate under the National Safety Code. Carriers plated in another province hold that province's NSC number instead, and Ontario doesn't ask them for a CVOR.

Do I need a separate safety certificate for every province I drive in?

No. The Motor Vehicle Transport Act says a safety fitness certificate issued by a province 'is valid throughout Canada.' You hold one, from the province where your trucks are base-plated.

How often does a CVOR certificate have to be renewed?

Every two years for carriers rated Excellent or Satisfactory, and every year for Satisfactory-unaudited or Conditional. The renewal fee is $51, and MTO sends a reminder 60 days before the certificate expires.

What is an NIR in Quebec?

The NIR (numéro d'identification au registre) is the number the Commission des transports du Québec assigns when a heavy vehicle owner or operator registers in its register (RPEVL). It starts with the letter R followed by seven digits, it corresponds to the NSC number, and the registration must be updated every year.

Does a Canadian carrier need a USDOT number to haul into the U.S.?

Yes, if it runs vehicles of 10,001 pounds or more in interstate commerce, which includes trips between the U.S. and Canada. A for-hire carrier moving regulated freight also needs FMCSA operating authority, and the USDOT record must be updated every two years.

Can a broker arrange loads by heavy vehicle in Quebec without registering?

The CTQ says only intermediaries on its list may offer transport intermediary services in Quebec, and a contract with an unregistered one is void. Its page doesn't address brokers based outside Quebec, so ask the CTQ before booking Quebec loads.

What's my Canadian DOT number? CVOR, NSC and NIR explained

Canada has no single "DOT number." Each province or territory issues a carrier a National Safety Code (NSC) number and a safety fitness certificate for the trucks plated there, and that one certificate is valid across Canada. In Ontario it's the Commercial Vehicle Operator's Registration (CVOR) certificate. In Quebec it's registration with the Commission des transports du Québec (CTQ), which assigns an NIR. A carrier that also hauls into the U.S. needs a USDOT number from FMCSA, and for most for-hire freight, operating authority as well.

The examples use Ashgrove Freight, a 140-truck carrier in Mississauga ON. This is general information, not legal advice; confirm details with the issuing office.

What is the National Safety Code, and who issues the number?

The National Safety Code is 16 standards kept by the Canadian Council of Motor Transport Administrators (CCMTA) and adopted or mirrored in provincial law. Three matter here: Standard 7 (carrier and driver profiles), Standard 14 (safety rating) and Standard 15 (facility audits).

CCMTA doesn't issue numbers. The legal chain:

The Motor Vehicle Transport Act, section 7, says no one may operate an extra-provincial carrier "except under a safety fitness certificate" issued by a provincial authority. Section 8 says that certificate "is valid throughout Canada."
The Motor Carrier Safety Fitness Certificate Regulations apply to trucks, tractors and trailers over 4,500 kg registered gross vehicle weight, and to buses seating more than 10. Each province must issue "a unique National Safety Code number" to carriers whose vehicles are plated there.
Standard 14 makes the base jurisdiction, the province where the vehicle is base-plated, responsible for the carrier's safety rating.
The same regulations require extra-provincial truck carriers to carry at least $1,000,000 of liability insurance per vehicle, or $2,000,000 for vehicles carrying dangerous goods that need an emergency response assistance plan.

So a carrier holds one certificate, from the province where its trucks are plated, and uses it everywhere in Canada.

Which registration applies in each province?

Jurisdiction	Registration	Issuer	Number	Who needs it	Official page
Ontario	CVOR certificate	Ministry of Transportation (MTO)	CVOR number	Ontario-, U.S.- or Mexico-plated trucks over 4,500 kg, buses seating 10 or more, tow trucks	ontario.ca
Alberta	Safety Fitness Certificate	Transportation and Economic Corridors	NSC number	Over 4,500 kg hauling outside Alberta; 11,794 kg or more inside Alberta only	alberta.ca
British Columbia	NSC Safety Certificate	Commercial Vehicle Safety and Enforcement (CVSE)	NSC number	Commercial vehicles licensed over 5,000 kg; buses seating 10 or more plus the driver	cvse.ca
Quebec	Registration in the RPEVL	Commission des transports du Québec	NIR (R + 7 digits)	Heavy vehicles of 4,500 kg or more, and all buses, plated in Quebec or operated there with U.S. plates	ctq.gouv.qc.ca
Other provinces and territories	Safety fitness certificate	The provincial or territorial NSC office	NSC number	Check with that office	CCMTA
United States	USDOT number, plus operating authority for most for-hire freight	FMCSA	USDOT number; MC number for authority	Vehicles of 10,001 lb or more in interstate commerce	fmcsa.dot.gov

Alberta requires a pre-entry program first: an online course and a knowledge test passed with 80% or more. Certificates run for up to three years, and renewal costs $123. In B.C., the application costs $200, includes a knowledge test and takes 12 to 14 weeks to review. For other provinces and territories, ask the provincial NSC office.

How does Ontario's CVOR certificate work?

Ontario requires a CVOR certificate for vehicles plated in Ontario, the U.S. or Mexico: trucks with a registered gross weight or actual weight over 4,500 kg, buses seating 10 or more, and tow trucks. Trucks plated in another province don't need one. Instead, MTO's safety manual says, they need "a safety fitness certificate (NSC number)" from that province, or an NIR from Quebec.

Applying. A new certificate costs $287.00 with HST: a $255 processing fee and a $32 learning and assessment fee. First-time applicants finish online courses within six months of applying.
In the cab. A copy goes in each vehicle.
Renewal. Every two years for carriers rated Excellent or Satisfactory, and every year for Satisfactory-unaudited or Conditional. The renewal fee is $51. MTO sends a reminder 60 days before expiry, and changes to your information are due within 15 days.
Abstracts. A Level 1 abstract is a one-page, two-year summary anyone can order. A Level 2 abstract adds five years of event detail and goes only to the carrier, by mail. Each costs $5.00 uncertified or $10 certified. Carriers can review their own record online free.
Checking someone else. MTO's free carrier safety rating enquiry searches by CVOR number or name.

How does Ontario rate a carrier's safety?

MTO's CVOR program reference guide (March 2026) lists five ratings: Excellent, Satisfactory, Satisfactory-unaudited, Conditional and Unsatisfactory. The main CVOR page lists four and leaves out Excellent. Satisfactory and Excellent need a passed facility audit. Without an audit, the best a carrier can get is Satisfactory-unaudited, and new operators start there. An Unsatisfactory rating suspends or cancels operating privileges "throughout Canada."

Ratings follow the overall violation rate (OVR): 24 months of collision, conviction and inspection points, as a percentage of a threshold set by fleet size, drivers and kilometres.

OVR, % of threshold	What MTO may do
0–34%	Nothing; keep monitoring your record
35–49%	Warning letter
50–84%	Facility audit; at 70%, the rating drops to Conditional
85–99%	Interview with a senior official and an action plan
100% or more	Meeting with the Deputy Registrar; possible suspension or cancellation

MTO's safety manual (2022) combines the three rates 2:2:1:

OVR = (2 × collision rate + 2 × conviction rate + inspection rate) ÷ 5

Excellent also takes an OVR of 15% or less and a collision rate of 10% or less at the time of rating. To keep it, the OVR has to stay at 20% or less and the collision rate at 15% or less.

What does Quebec require?

Quebec carriers register in the Registre des propriétaires et des exploitants de véhicules lourds (RPEVL) with the CTQ. It covers every bus and any vehicle or trailer rated 4,500 kg or more.

Who registers. Owners and operators of Quebec-plated heavy vehicles, and owners of U.S.-plated heavy vehicles operated in Quebec. Carriers plated in other provinces register with their own province, and the CTQ accepts that registration while it stays valid.
The number. Registration assigns an NIR, usually within two business days: the letter R followed by seven digits. The CTQ's English page says the number "corresponds to the National Safety Code (NSC) number." Registration must be updated every year.
The rating (cote de sécurité). Satisfaisant (satisfactory), conditionnel (conditional) or insatisfaisant (unsatisfactory). At registration, the CTQ assigns satisfaisant marked "non audité" (not audited), or a conditionnel or insatisfaisant rating. An unsatisfactory rating bars the registrant from operating heavy vehicles.

Quebec also regulates the middle of the deal. An intermediary in transport services is anyone who, for pay, arranges transport of people or goods by heavy vehicle between other parties. The CTQ's examples include a load broker, a freight forwarder and a carrier that sometimes brokers. Only intermediaries on the CTQ's list may offer those services in Quebec, and a contract with one that isn't registered, or didn't renew, is "nul de plein droit" (void by law). You can look up an intermediary by name or intermediary number (NI) in the CTQ's online company records.

What does a Canadian carrier need to haul into the U.S.?

On the U.S. side, a provincial certificate isn't enough.

A USDOT number. FMCSA requires one for vehicles of 10,001 pounds or more in interstate commerce, which includes trips between a U.S. state and "a place outside of the United States." Federal rules (49 CFR 390.19T) name Canada-domiciled carriers directly.
Operating authority. Carriers that haul regulated freight owned by others for pay, and brokers that arrange it, need operating authority on top of the USDOT number. It's usually shown as an MC number. Private carriers and carriers hauling only exempt commodities don't need it. Each type of authority costs US$300.
The biennial update (MCS-150). The USDOT record must be updated every two years, even if nothing changed. The last digit of the USDOT number sets the month: 1 is January, and so on up to 9 for September, with 0 for October. The next-to-last digit sets the year: odd digits file in odd years, even digits in even years. Missing it deactivates the number and can cost up to US$1,000 a day, to a maximum of US$10,000.

FMCSA is moving registration to a new system, Motus, and has proposed no longer assigning MC numbers. Authority would show as a suffix on the USDOT number, "C" for a property carrier and "B" for a broker. That needs a rulemaking first. Authority also doesn't make domestic U.S. moves legal for a Canadian truck: see cabotage rules.

Worked example: Ashgrove Freight and Ashgrove Logistics

Ashgrove Freight's trucks are plated in Ontario, so Ontario is its base jurisdiction and the CVOR certificate is its safety fitness certificate everywhere in Canada. Every number below is an example figure, not a real registration or record.

Question	Ashgrove Freight
Canadian number	CVOR 000-000-000 (example)
Rating and renewal	Satisfactory (example), so renewal every two years for $51
Next CVOR expiry	March 31, 2027 (example date); MTO's reminder, 60 days earlier, lands January 30, 2027
Trucks into Quebec	No RPEVL registration: Ontario-plated trucks run on the CVOR
Liability insurance	At least $1,000,000 per vehicle, on each of its 140 trucks
U.S. runs (48213 to Joliet IL, 48226 to Cleveland OH)	USDOT 0000012 (example) and property carrier authority MC-000000 (example)
Next MCS-150	Last digit 2 means February; next-to-last digit 1 is odd, so odd years: due February 28, 2027

The OVR check. Say Ashgrove's CVOR record shows a collision rate of 20.00%, a conviction rate of 30.00% and an inspection rate of 45.00% (all example figures):

OVR = (2 × 20.00 + 2 × 30.00 + 45.00) ÷ 5 = 145.00 ÷ 5 = 29.00%, under the 35% warning-letter line.
If the conviction rate climbed to 45.00% with the other two unchanged: (2 × 20.00 + 2 × 45.00 + 45.00) ÷ 5 = 175.00 ÷ 5 = 35.00%, the point where MTO may send a warning letter.

A 15-point rise in one rate moved the overall rate 6 points, because convictions count double.

The brokerage question. Ashgrove Logistics, the group's brokerage, needs its own FMCSA broker authority to arrange U.S. loads. If it starts arranging Quebec loads on heavy vehicles for pay, it has to answer the CTQ question before the first booking: does it need to be on the intermediary list? The CTQ's page doesn't say how the rule applies to a broker based in Ontario, so ask the CTQ.

How should a TMS hold this?

Registrations are numbers with due dates. Hold them like other expiring records:

The carrier's own registrations, each with number, issuer, rating and next due date.
Every outside carrier a brokerage tenders to, with the rating checked on the issuing province's lookup.
Driver and unit documents on the driver and the truck, so nothing expires mid-trip.

Roadmark's part is narrower. Through the carrier portal, a carrier uploads its packet once. Roadmark vets the carrier and runs fraud checks at onboarding, then re-checks authority and insurance every day against the source. As the brokers page shows with Brightwater Carriers, a carrier that fails a check gets no new tenders. For a carrier's own fleet, Roadmark tracks licences, permits, annual inspections, medical cards and insurance for every driver, unit and trailer, and sends reminders weeks ahead.

Roadmark is Canadian-owned. Canadian customers' cloud data is hosted in Canada, and the app and support are available in English and French. See the Canadian TMS page, or the ACE and ACI eManifest guide for the paperwork at the border.
