How risk signals work

Nothing in the FMCSA record matched our risk signals. That is not a guarantee, and it does not confirm who you are talking to; follow the checks below. Authority and insurance are last known from May 14, 2026.

Green means the FMCSA record shows it. It does not confirm who you are talking to, or that a policy covers your specific load.

Not a live check. FMCSA has not published a Motus record for this carrier, so authority and insurance show the last known status from May 14, 2026. Confirm on Motus ↗ before booking.

Insurance on file

Liability (BI&PD) pays for injury and damage to other people and property; it does not cover the freight. Cargo insurance covers the freight. FMCSA only requires cargo filings from household goods carriers and freight forwarders, so most carriers file none: ask for a cargo certificate that fits your load. No cargo cover filed with FMCSA.

How these rates are calculated

Period: Oct 19, 2024 – Oct 19, 2026. Vehicle rate = vehicle inspections with a vehicle out-of-service order ÷ vehicle inspections (levels 1, 2, 5 and 6). Driver rate uses levels 1, 2, 3 and 6. The Ontario average covers 27,972 vehicle and 49,096 driver inspections of all Ontario-based carriers in this period. It mixes every type of operation, so compare with care; rates based on a handful of inspections say little. FMCSA's own SMS measures are weighted differently: SMS profile ↗ · SAFER snapshot ↗

Violations in FMCSA's SMS last 24 months

24 violations counted in FMCSA's Safety Measurement System (SMS), 1 of them serious enough to put the driver or vehicle out of service.

Why is this different from the 25 violations above?

The inspections section's number counts every violation written on the inspection reports in our Oct 19, 2024 – Oct 19, 2026 window. The SMS count comes from FMCSA's own monthly SMS snapshot, which uses its own 24-month window and only the violations it scores. Both are FMCSA figures; they measure different things.

"Share" is this company's mix of violations; the Ontario column is the mix across all Ontario-based carriers, so you can see which kinds of problems stand out. A high count partly reflects fleet size and how often trucks are inspected.

Questions about 2539937 ONTARIO INC

What does 2539937 ONTARIO INC's operating authority allow?

MC71949: Common carrier (may haul regulated property for hire for the general public).

Which information about 2539937 ONTARIO INC is old or missing?

Operating authority is the last known status from the FMCSA snapshot of May 14, 2026, not a current check. Insurance filings are from the same May 14, 2026 snapshot. FMCSA has not issued a safety rating, which means no compliance review is on record, not that the carrier is unsafe.

What should I verify before booking 2539937 ONTARIO INC?

Confirm the authority and insurance on the Motus record for USDOT 3091737. Call the company back on the phone number on file, (519) 843-3748, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC71949, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
