Submetering for Multi-Unit Commercial Buildings in Ontario

While submetering is most commonly associated with residential buildings, multi-unit commercial properties also benefit from suite-level metering. Commercial submetering has different considerations from residential applications, but the core principle is the same: each tenant pays for what they use.

In a commercial building, tenants may have very different electricity consumption profiles. A restaurant uses significantly more electricity than an office suite of the same size. A data-intensive business may have high 24/7 consumption, while a retail shop uses energy primarily during business hours. Bulk metering and cost allocation formulas often do not reflect these differences fairly.

Submetering provides accurate, measured allocation of electricity costs. Each commercial tenant receives a bill based on their actual consumption. This eliminates disputes about who is subsidizing whom and provides each tenant with the information they need to manage their own energy costs.

Commercial tenants often have more complex electrical installations than residential suites. Multiple circuits, three-phase power, and dedicated equipment connections may require different metering approaches. A qualified submetering provider will assess the electrical configuration of each unit and design the metering installation accordingly.

Lease structures in commercial buildings vary. Some leases include electricity in the rent (gross lease), some charge it separately (net lease), and some use a modified approach. When transitioning to submetering, the lease terms need to align with the new billing structure. Consult with your legal advisor to ensure lease modifications are appropriate.

The OEB Unit Sub-Metering Code applies to both residential and commercial submetering. The same standards for billing accuracy, customer service, and consumer protection apply regardless of building type.
