Understanding the steps to renew a commercial driver's licence in Ontario can streamline the process and ensure compliance with regulations.

Renewing a commercial driver’s licence in Ontario involves navigating a structured process that varies depending on the status of your licence. Whether your licence has expired for less than three years or more than three years, the requirements differ significantly. Knowing these nuances can help you avoid potential fines, unnecessary stress, and the risk of delays in returning to the road.

How to Renew Your Commercial Licence
First and foremost, it's essential to remember that commercial licences cannot be renewed online. Renewal necessitates an in-person visit to a DriveTest Centre, as they handle commercial licensing matters. While ServiceOntario manages G or M licences, all commercial renewals go through the DriveTest facilities.
1. Renewing an Expired Licence (Less Than Three Years)
- To start the renewal process, visit a DriveTest Centre.
- You will need to complete several tests and provide specific documents:
- Vision test to assess your eyesight
- Written knowledge test that evaluates your understanding of traffic rules
- Road/practical test, although this may not always be required for shorter expirations
- A medical examination report, which must be submitted in person
2. Renewing an Expired Licence (More Than Three Years)
If your commercial driver’s licence has been expired for over three years, the process becomes more complex. You will need to reapply for a full Class G licence. This means you must satisfy all requirements of the Graduated Licensing Program, which includes:

- Vision test
- Knowledge test
- Road/practical test
- A medical examination report
- For those applying for a Class B or E licence, a criminal record check is also mandatory
3. Medical Reporting Obligations
Another critical aspect of renewing a commercial licence is adhering to medical reporting requirements based on your age. Commercial drivers must submit a periodic medical report, as outlined below:
- Drivers under 46 years of age must renew every five years
- Ages 46 to 64 require renewal every three years
- Drivers 65 and older must provide a medical report annually
Failure to comply with these requirements can lead to downgrading your licence to a non-commercial (Class G) status.

4. Changes in Air Brake (Z) Endorsement
As of September 1, 2023, the method for obtaining the air brake endorsement has changed. The traditional air brake knowledge test is now replaced by an online learning module. Once you complete this module, you must present your Certificate of Completion and your licence at a DriveTest Centre to finalize your renewal. This process still requires a vision test and the knowledge test relevant to your commercial class.
5. Temporary Licence Issuance
After successfully completing all required steps at the DriveTest Centre, you will receive a Temporary Driver’s Licence (TDL), valid for 90 days. This temporary licence allows you to continue driving legally while you await the arrival of your new permanent card via mail.
6. Previous COVID-19 Extensions (Now Lapsed)
During the pandemic, special provisions allowed for licences that expired between March 1, 2020, and February 28, 2022, to remain valid. However, this extension has ended, and all drivers must adhere to the regular renewal process moving forward.
Summary of Renewal Steps
| Condition | Next Steps |
|---|---|
| Expired < 3 years | Visit DriveTest → Complete Vision + Knowledge + possible Road test + Medical form |
| Expired > 3 years | Reapply for G licence → Complete Graduate testing → Reapply for commercial licence |
| Air Brake (Z) Endorsement | Complete online module → In-person Vision + Knowledge test |
| Age-based Medical Reporting | Submit medical report every 5 / 3 / 1 year, depending on age |
| During Renewal | Receive Temporary Licence (90 days) until permanent card arrives |
| COVID Extensions | Not applicable—return to standard rules |
Conclusion
Keeping track of your commercial licence renewal is paramount for all Ontario drivers. Missing deadlines can lead to extra testing or even restarting the licence process entirely. By familiarizing yourself with the varying requirements for renewal—whether your licence has recently expired, lapsed for several years, or falls under special rules for commercial drivers—you can avoid complications and maintain your driving privileges. Taking a proactive approach to review your renewal timeline will save you from potential hassles down the road.
