You received an MTO letter. Here is what happens next.
An MTO intervention letter, audit notice, or carrier safety review is time-sensitive. What you do in the next 30 days determines whether your safety rating stays intact — or gets downgraded.
Do not wait to respond to MTO correspondence.
Failing to respond or respond adequately to an MTO notice can result in an automatic safety rating downgrade without a hearing. If you have a scheduled audit date, the preparation window is now.
What type of MTO contact did you receive?
Warning Letter
14–30 daysThe MTO is flagging your CVOR violation rate as approaching or exceeding acceptable thresholds. This is a pre-intervention signal — the time to correct course before the next step is now, not when the next letter arrives.
Pull your CVOR abstract today. Identify which violation categories are triggering the flag. Begin closing open compliance gaps before the 30-day follow-up window closes.
Carrier Safety Review (CSR) Notice
30–60 daysYou have been scheduled for a Carrier Safety Review — a formal MTO facility audit that reviews your driver files, maintenance records, HOS logs, and overall compliance management. The auditor will score your operation the same way the MTO scoring system does.
Begin an immediate compliance inventory. Every missing document, expired record, or incomplete file the auditor finds is a finding against your safety rating. You need an independent review of your files before that date.
Conditional Safety Rating Notice
ImmediateYour safety rating has already been downgraded to Conditional. This is visible to insurance companies and can trigger premium increases or cancellation. You must demonstrate corrective action within the MTO's specified timeframe or face further downgrade to Unsatisfactory.
Contact us immediately. A Conditional rating response requires documented corrective action, a compliance management plan, and evidence of active remediation. This is not a situation to manage alone.
Unsatisfactory Safety Rating / Suspension Notice
Immediate — LegalAn Unsatisfactory rating or suspension notice may result in a suspension of your operating authority. This requires immediate legal and compliance action. Your ability to operate under this CVOR may be at risk.
You need legal counsel familiar with MTO proceedings and a compliance specialist to document corrective action. Call us immediately — we can help coordinate the compliance side and refer you to transport law resources.
What We Do in the First 48 Hours
When you call with an MTO notice in hand, here is exactly what happens.
CVOR Abstract Review
Brian pulls or reviews your current CVOR abstract to identify exactly which violation categories triggered the notice and how far above threshold you are.
Compliance Gap Assessment
Rapid review of your driver files, vehicle maintenance records, and HOS situation to identify what the auditor will find — before they do.
Written Response Strategy
A written CVOR exposure summary with ranked findings, corrective action priorities, and a response framework you can use with the MTO — or bring to legal counsel.
Active Remediation Support
Ongoing support to close gaps, build the documentation file, and help present corrective actions in a format aligned with MTO audit expectations.
What the MTO auditor reviews in a facility audit
The MTO Carrier Safety Review evaluates your compliance across four categories. Every gap found becomes a finding against your safety rating.
Driver Qualification (35%)
- Valid driver's licence class for the vehicle operated
- Annual driver abstracts — one for every active driver
- Signed annual driver reviews on file
- Driver medical certificates (where applicable)
- New driver probation documentation
Vehicle Maintenance (35%)
- Annual safety inspections — current for every vehicle
- Pre-trip inspection records — daily DVIRs on file
- Preventive maintenance schedule and completion records
- Defect reporting and repair documentation
- CVOR registration — current and matching operating CVOR
Hours of Service (15%)
- Logbooks or ELD records for all drivers
- HOS cycle compliance — Ontario/federal rules
- Supporting documents for on-duty time
- Record of violations and corrective actions
- ELD mandate compliance (mandatory since June 2023 for affected carriers)
Accident Record (15%)
- Accident register — documented for every reportable collision
- Preventability determinations on file
- Corrective actions documented for each preventable accident
- Driver counselling records following accidents
- Trending analysis — pattern identification
Important: The MTO uses a weighted scoring method — a carrier scoring below 75/100 across these categories is considered to have a deficient safety management program, which triggers a safety rating downgrade. Read how CVOR scoring works.
Do not manage an MTO audit response alone.
The first call is a structured 30-minute review of your current CVOR position, the notice you received, and the highest-priority actions before your audit date. Written summary delivered the same day.
