Unit sub-metering

Section 57(c.1) of the Ontario Energy Board Act, 1998 states that no person is permitted to engage in unit sub-metering without a licence.

For each licence application filed with the OEB, the applicant must submit a non-refundable application fee of:

  • $1000 for applicants applying for a new unit sub-metering licence;
  • $200 for applicants applying to renew their unit sub-metering licence and have paid their annual registration fee.

A licensee must pay an annual registration fee for every year of its licence. The annual registration fee for a licensed unit sub-meter provider is $800.

Online Licence Application Form

The OEB has launched a new, online portal for filing licence applications, a key commitment in the OEB’s Digital First strategy. The portal is now open to file Unit Sub-Metering licence applications online and use a new e-payment service. Note: as of July 19, 2022, PDF application forms will no longer be accepted.

Current licensees (July 19, 2022): An account has been created for your Primary Licence Contact to access the portal. The Primary Licence Contact will receive an email from OEB Webmaster asking for a password to be created. Please do this step right away to complete the registration.
