Ontario has a sound history of having high quality land ambulances and emergency response vehicles (ERV). This has been achieved by setting standards for the construction and conversion of emergency vehicles that meet the need for patient care, delivery, and safety. To ensure that these standards are well known and understood by all, the Ministry of Health developed and implemented the Ontario Provincial Land Ambulance & Emergency Response Vehicle Standard (Standard) The current version of the Standard describes the minimum requirements for new and re- mounted ambulances to be used in the province. Ambulances and ERVs operated by service providers must comply with this Standard. Compliance requirements for the Standard are accomplished through a series of performance tests. The test results are submitted to the Director, Emergency Health Regulatory and Accountability Branch for certification approval. This testing process is normally the responsibility of the ambulance conversion vendor. Certification is necessary to show compliance with the Standard for any ambulance and ERVs intended for use in Ontario.

Certification requirements and continued compliance details are outlined in section 19 of the Standard for ambulances and Annex ‘A’ for ERVs.

The certificate shall remain valid, and the vehicle deemed compliant to the Standard provided that:

  • The design, material, dimensions, and equipment are the same as the ambulances and ERVs tested and presented for review,
  • The ambulance or ERV is manufactured in the same manner as the model tested and presented for review,
  • The chassis is the same, make, model, engine and specifications as the model presented for review (differences in model years can be accepted so long as equivalent to model presented for review)

Certificate extensions can be obtained by making application to the Director, Emergency Health Regulatory and Accountability Branch, it remains the sole discretion of the Director to extend valid certificate date.

The compliance certification requirements for the remounting of a patient compartment module on a new chassis are described at Annex ‘B’ of the Standard.

The following tables list the current conversion contractors and their models that are certified for use in Ontario.
