The Electricity and Gas Inspection Act (EGIA) sets out requirements for the performance of measuring devices when they are used to establish the basis of a charge for the purchase or sale of electricity. Electric Vehicle Supply Equipment (EVSE), commonly known as EV chargers, fall within the scope of the requirements of this Act when they are used to bill a customer for the amount of electricity delivered during a charging session (i.e. per kilowatt-hour or kWh).
Measurement Canada evaluates and type approves EVSE that will be used to bill for an EV charge (based on kWh consumed during a charging session) before they are permitted to be used in Canada. These devices must also be inspected and certified by Measurement Canada or an Authorized Service Provider when they are used in the marketplace to ensure they measure accurately and comply with other requirements of the EGIA and associated regulations and specifications.
Overview
This consultation seeks feedback on proposed provisional inspection specifications and procedures for the inspection and verification of installed Level 1 and Level 2 AC EVSE that have been type-approved by Measurement Canada and are used to bill a customer for the amount of electricity (kWh) delivered during an EV charging session. The proposed provisional specifications and procedures incorporate comments received during the 2024 consultation on proposed EVSE inspection and verification requirements. They also include a proposed change to the EVSE reverification period, provisions to allow for remote displays (with some conditions) as well as proposals to address feedback received during subsequent discussions with organizations operating within the EV charging landscape.
Requirements in the proposed provisional inspection specifications and procedures are aligned with approaches being pursued in other countries for the inspection and verification of installed Level 1 and Level 2 AC EVSE used to bill a customer for the amount of kWh delivered during an EV charging session.
Note: New specifications are identified as provisional to provide Measurement Canada and industry with an opportunity to implement the requirements and to gather and analyse data on device performance aligned with the requirements in practical scenarios. This approach allows revisions to the specifications if the desired results, including measurement accuracy performance, are not achieved. Once the assessment is completed and no further changes are envisioned, the "provisional" aspect of the specification is removed. In all cases, Measurement Canada will work with industry to minimize the impact of changes to the requirements.
Providing your feedback
This consultation will close on Monday, August 3, 2026.
This consultation seeks feedback on the proposed requirements in the following two documents. Your comments will help to inform the provisional specifications and procedures that will be used to inspect and verify installed AC Level 1 and Level 2 EVSE used to bill a customer based on the amount of electricity delivered during an EV charging session.
- PS-EVSE-03 — Provisional specifications for the verification, reverification, and installation of electric vehicle supply equipment
- P-EVSE-02 — Procedure for the verification and reverification of electric vehicle supply equipment
Your comments should include the following:
- the title of the document and the specific sections or subsections of the document that your comments relate to;
- details of any concerns with the proposed requirement; and
- suggestions for changes to address your concerns.
Through this consultation, Measurement Canada wants to hear from businesses including EVSE owner/operators and installers, manufacturers, Authorized Service Providers, non-governmental organizations, associations and members of the public.
Please send your written comments or questions to mcfeedback-retroactionmc@ised-isde.gc.ca with "EVSE provisional inspection specifications and procedures" in the subject line.
Thank you for your participation.

Other related consultations
Measurement Canada is also seeking feedback on Specifications for EVSE type-approval. The Consultation on follow-up proposed changes to the Specifications for the approval of type of Electric Vehicle Supply Equipment (EVSE) closes on August 3, 2026.
Annex A – Summary of proposed changes to the Provisional specifications for the verification, reverification, and installation of electric vehicle supply equipment
Proposed changes to the provisional inspection specifications and procedures include:
- a reverification period of eight years for installed AC Level 1 and Level 2 EVSE;
- the ability to employ remote displays on EVSEs, provided certain conditions are met; and
- requirements related to cables.
It should be noted that similar proposed changes were made to P-EVSE-02 – Procedure for the verification and reverification of electric vehicle supply equipment, in order to align with the proposed revisions to the Specification.
Annex B – Key proposed changes within the Provisional specifications for the verification, reverification, and installation of electric vehicle supply equipment
| Section or subsection | Proposed change | Text |
|---|---|---|
| 1.0 Purpose | Addition |
These provisional specifications establish requirements for the verification, reverification, and installation of electric vehicle supply equipment (EVSE) that are approved by Measurement Canada for use in trade measurement. |
| 5.0 Definitions | Revision |
Client interface Revised wording in definition |
| Addition |
Display Part of an EVSE that consists of the client interface either continuously or on demand. It may be an integral part of an EVSE (local display) or a separate module (remote display). Note: A display may also be used to indicate other relevant information to the EVSE. |
|
| Revision |
Ready condition The condition in which the EVSE is ready to begin a charging session or transaction. |
|
| Revision |
Reference meter A measuring instrument having errors traceable to the National Research Council of Canada and used to establish the true value of a measurement. |
|
| 7.4 Reverification period | Revision |
Any EVSE used to establish the price for the sale of electricity based on a legal unit of measurement, as prescribed in section 3.1 of the EGIA, must be reverified within eight (8) years subsequent to the previous verification or reverification date unless otherwise specified. |
| 8.4 Displays | Revision |
An EVSE must be capable of displaying all legally relevant data. The display capability can be provided using a local display or a remote display that complies with the requirements of 8.4.1 in addition to the rest of 8.4. The display used to present legally relevant data must be readily and reasonably accessible, and legible to the user during the entirety of the transaction under normal operating conditions. The EVSE's display must refresh every 30 seconds at a minimum. |
| 8.4.2 Agreement between indications | Revision |
At the end of a transaction, all quantity, unit price and total price indications within a measuring system must agree for each transaction, including the resolution of the indications. If there is a disagreement between indications, the indication of the local display, if present, will be taken as the correct indication. |
| 8.7 Cables | Addition |
Any cables installed or replaced subsequent to the verification and sealing of the EVSE must be as specified in the NOA. |
| 8.13 Reset to zero | Revision |
The EVSE must have a ready condition. The ready condition must include, at a minimum, an unambiguous zero registration for both energy dispensed and total price. The EVSE must be in a ready condition at the start of any charging event for which a charge is to be applied. The ready condition may include other indications. The EVSE must not register energy when there is an interruption during any charging event for which a monetary charge is to be applied. |
