The MX 164A is a Type III ambulance designed to match Ontario EMS needs, with an interior layout built around organized workflows, clear access to equipment, and a safe, ergonomic care environment. Trusted in Ontario and recognized internationally, the MX 164A delivers a balanced combination of space, functionality, and performance.
Ontario EMS sparked its creation in 2013, shaping a design centered on the way paramedics work across the province. The model is compliant with Ontario Ministry of Health certification.
Built through years of direct feedback from Ontario paramedics, the MX 164A features a layout and equipment configuration tailored to provincial practices. From streetside cabinetry sized for MOH blue bins to cab requirements aligned with local protocols, every detail reflects the realities of Ontario operations.
The MX 164A integrates modern systems such as the MMC digital control interface, last generation of multiplex and new emergeny lighting features options. These technologies support clearer workflows, improved safety, and easier management of critical vehicle functions.
Proven across Ontario since 2013, the MX 164A has grown into one of Demers’ best-selling Type III platforms worldwide. Its long service record and workflow-driven design have made it a trusted choice for EMS in diverse regions and operating conditions. Whether in urban systems or regional services, its performance continues to stand out.
Technical issues can be identified in no time with the MMC multiplex system. Its Bluetooth connectivity provides real-time access to electrical data, enabling quicker diagnostics, reduced downtime, and a vehicle that is ready for deployment at all times.
