Do You Need DOT Numbers in Canada?

YES, if you operate:

• Any commercial vehicle with a registered gross weight over 4,500 kg (9,921 lbs)
• Vehicles crossing provincial borders (interprovincial commerce)
• Trucks entering the United States (requires both Canadian CVOR/NSC AND US DOT)
• Vehicles hauling dangerous goods at any weight

NO, if you operate:

• Pickup trucks under 4,500 kg for local deliveries (within your province)
• Personal-use vehicles (no commercial activity)
• Farm vehicles used exclusively for agricultural purposes on private land

Canadian DOT Marking Requirements (By Province)

Province/Territory	Registration Type	Lettering Size	Placement
Ontario	CVOR (Commercial Vehicle Operator's Registration)	2" minimum height	Both cab doors, contrasting colour
Quebec	NSC (National Safety Code)	2" minimum height	Both sides of vehicle
Alberta, BC, Saskatchewan, Manitoba	NSC Certificate	2" minimum height	Both cab doors
Atlantic Provinces (NS, NB, PEI, NL)	NSC + Provincial Plate	2" minimum height	Both cab doors
Yukon, NWT, Nunavut	NSC + Territorial Registration	2" minimum height	Both sides of vehicle

What Information Must Be Displayed?

Mandatory Elements (All Provinces)

1. Legal business name (as registered with your provincial transportation authority)
2. CVOR or NSC number (format varies: "CVOR 1234567" in Ontario, "NSC AB 123456" in Alberta)
3. City and province of your business address (e.g., "Port Colborne, ON")

Optional (But Recommended)

• Phone number (makes it easier for customers and roadside inspectors to contact you)
• Website (professional appearance, helps with lead generation)
• Truck number/unit number (if you operate a fleet)

DOT Lettering Example (Ontario CVOR)

Cost for this layout: $129 (both cab doors, black or white vinyl, includes installation guide)

Lettering Size & Colour Rules

Height Requirements

• Minimum 2 inches for all text (measured from bottom to top of capital letters)
• Company name can be larger (3-4 inches) for visibility, but CVOR/NSC must be at least 2 inches
• Use simple, legible fonts (Arial, Helvetica, Impact)—no script or decorative fonts for compliance text

Colour Contrast Rules

Lettering must contrast sharply with the vehicle's door colour:

• White trucks: Use black, dark blue, or dark green vinyl
• Black/dark trucks: Use white or yellow vinyl
• Red/bright trucks: Use white or black (test contrast with inspector's 20-foot visibility rule)

Reflective Lettering (Night Visibility)

Not legally required in Canada, but highly recommended for safety and professionalism. Reflective vinyl (3M Diamond Grade or Engineer Grade) costs the same as standard vinyl but glows under headlights at night.

Upgrade to reflective: Add $30 to any DOT lettering order. Specify "reflective" when ordering.

Where Exactly Do Decals Go?

Standard Placement (Most Trucks)

• Both cab doors (driver and passenger sides)
• Centered vertically on the flat door panel, below the window line
• 12-18 inches from the door edge (allows for door handles and trim)
• Readable when doors are closed (don't place over seams or body lines that distort text)

Special Cases

• Trucks without doors (flatbeds, dump trucks): Place on both sides of the cab, just behind the cab corner
• Trucks with tool boxes/storage: Place above or below the box, maintaining 2-inch text height
• Sleeper cabs: Use the door if there's enough flat space; otherwise, place on the sleeper panel behind the door

We include a positioning template with every DOT lettering order—tape it to your door, align the decal, remove the template. Guaranteed symmetrical placement.

US DOT Numbers for Cross-Border Hauling

If your trucks enter the United States, you need BOTH Canadian (CVOR/NSC) and US DOT markings.

US DOT Requirements

• USDOT number (obtained from FMCSA: fmcsa.dot.gov)
• 2-inch minimum lettering (same as Canada)
• Placement: Both sides of the power unit (cab or tractor)
• Format: "USDOT 1234567" in contrasting colour

Combined CVOR + USDOT Layout Example

Cost for combined layout: $149 (both cab doors, includes both Canadian and US compliance)

Frequently Asked Questions

Do I need DOT numbers if I only haul within my city?

Depends on your truck's weight. If your vehicle's registered gross weight exceeds 4,500 kg (9,921 lbs), you need CVOR/NSC even for local-only operations within Ontario/your province. If you're under 4,500 kg and only operate locally, you're exempt—but adding your business name and phone is still smart for marketing.

Can I use magnetic signs instead of vinyl decals?

Technically yes, but not recommended. Magnetic signs satisfy the legal requirement for removable markings, but they fall off on highways, fade quickly, and look unprofessional. Vinyl decals last 7+ years and cost less than quality magnetic signs. If you absolutely need removable markings (shared/rental trucks), budget $150-$200 per set of magnetic DOT signs.

What if my CVOR/NSC number changes?

Rare, but it happens if you restructure your business or transfer ownership. When your number changes, you have 30 days to update your truck markings (Ontario rule; varies by province). We store your approved design for 2 years—reordering with a new number is a 10-minute phone call and 3-day turnaround.

Do trailers need DOT markings too?

Yes, in most cases. If your trailer's registered gross weight exceeds 4,500 kg, it must display your company name and CVOR/NSC number on both sides (near the front or rear, doesn't have to be on doors). Cost: $99 for both sides (12" × 30" layout). Some provinces allow "TRAILER OPERATED BY [CARRIER NAME] CVOR XXXXX" format.

Can I add my logo to DOT lettering?

Absolutely. As long as the mandatory text (company name, CVOR/NSC, city/province) is at least 2 inches tall and high-contrast, you can add logos, taglines, or graphics. We'll design a layout that combines compliance and branding. Budget $179–$299 for DOT lettering + logo (depending on logo complexity).

How long does DOT vinyl lettering last?

7+ years outdoors with our 3M cast vinyl. Ontario road salt, winter ice, and summer UV won't crack or fade it. Hand-wash your truck or use touchless car washes (avoid harsh brush washes). Expect the lettering to outlast your truck's paint job.

What happens if I get caught without proper markings?

Fines vary by province:
- Ontario: $310 for missing CVOR, $155 for improper lettering size/contrast
- Quebec: $350–$700 depending on severity
- Alberta/BC: $200–$500
- Repeat offences: Trigger safety audits, higher insurance rates, potential carrier certificate suspension
Bottom line: $79 for compliant lettering is way cheaper than one fine.

Can I order DOT lettering online without talking to anyone?

Not yet. Every truck is different (door colour, layout preferences, provincial rules), so we require a quick consultation to ensure compliance. Email info@niagarastandsout.com or call 289-228-7021. We'll send a proof within 24 hours, you approve via email, and we process payment + ship. Takes 5 minutes of your time total.
