Introduction
Measurement Canada (MC) is an agency of Innovation, Science and Economic Development Canada. It is responsible for ensuring accuracy in the selling of measured goods and energy (electricity and natural gas), enforcing the laws related to measurement accuracy, approving and inspecting measuring devices, and investigating complaints of suspected inaccurate measurement. MC fulfills its mandate by enforcing the Weights and Measures Act (WMA), the Electricity and Gas Inspection Act (EGIA), and their associated regulations.
To ensure compliance with these Acts, MC evaluates and approves measuring devices before they are authorized for use in trade within Canada.
As technology evolves, measuring devices increasingly rely on software, which can influence measurement accuracy and performance. MC has been developing harmonized requirements for the evaluation of software in software-controlled measuring devices, so the measurement functions of these devices remain reliable, accurate, and secure for use in trade. These new requirements will provide guidance to ensure that software-controlled measuring devices that are approved and inspected under the WMA or the EGIA continue to meet applicable performance and sealing requirements.
Objectives
MC completed an external consultation on a new set of requirements for evaluation of software in software-controlled measuring devices in January 2026. The consultation was aimed at achieving three main objectives.
First, MC wanted to understand the operational impacts and practical challenges that stakeholders may face once the proposed requirements are in place.
Second, the agency sought to clarify ambiguities or perceived barriers concerning practical measures such as software identification, update processes, sealing provisions, and traceability.
Finally, the consultation aimed to gauge industry readiness and collect feedback that would help shape a practical, well-phased transition period for everyone involved. The results aim to provide general direction for Measurement Canada's internal planning, inform targeted outreach and training, and support ongoing communication regarding the requirements' rollout.
Who we heard from
The consultation took place from October 14, 2025, to January 23, 2026. Invitations were sent to stakeholders through internal and external distribution lists.
Invitations were sent through multiple channels, including direct communication via distribution lists, targeted emails to industry stakeholders, and public notices on the Measurement Canada website. In total, 17 respondents provided feedback, representing a broad mix of industry associations, utilities, and Electric Vehicle Supply Equipment (EVSE) manufacturers. Respondents were encouraged to provide input either through written submissions addressing specific points of concern or proposing amendments.
What we heard
The consultation focused on gathering feedback from stakeholders regarding the harmonized requirements for the approval of software-controlled measuring devices under both the Weights and Measures Act (WMA), and the Electricity and Gas Inspection Act (EGIA). The scope of the consultation encompassed policy considerations and concerns related to the implementation of the requirements.
Engagement
Stakeholders appreciated the opportunity to share their views and propose suggestions and welcomed MC's efforts to modernize software requirements in step with current and future measurement technologies.
Stakeholders recognized that these requirements could significantly shape the process for type approval, compliance, software lifecycle management, and the timelines for deployment. As a result, stakeholders stressed the importance of implementing the requirements in a way that is clear, balanced, and practical.
Many stakeholders welcomed the opportunity to share their practical experience with device sealing and protection, particularly in cases where frequent software updates are expected. Participants also acknowledged the importance of traceability and audit trail requirements that will support transparency, while emphasizing the need for these requirements to remain efficient and effective.
Software Updates
Some respondents raised questions around managing updates to software versions, addressing bug fixes, and identifying which parts of the software are relevant for regulation. There was strong support for approaches such as software separation, traced updates, and the usage of audit trail functions. These solutions would allow updates of legally non-relevant software without the need for re-evaluation. Stakeholders also highlighted the value of keeping these requirements in line with international documents such as OIML D31 and WELMEC 7.2 and staying current as these documents evolve.
Innovative Designs
Stakeholders offered their own insights regarding scenarios that involve complex device designs, to help ensure that evolving technologies can be accommodated without compromising measurement integrity or slowing innovation. Additionally, respondents emphasized the importance of clear technical guidance, and expressed a desire for information on the type approval process, including expectations for documentation, attestation, and software evaluation.
Respondents showed widespread support for a flexible and reasonable approach to legacy devices, recognizing the importance of transitional efforts that support continued use and modernization. Overall, stakeholders expressed appreciation for the collaborative approach and looked forward to continued engagement and support from Measurement Canada.
Conclusions and next steps
Measurement Canada sincerely thanks all respondents for their thoughtful and constructive feedback. The insight and proposed solutions offered during this consultation will play a vital role in finalizing the harmonized requirements and shaping the tools and guidance needed for implementation. The agency is committed to working closely with stakeholders by providing clear information, training material, and ongoing support, ensuring a smooth and effective transition to the harmonized requirements for software-controlled measuring devices.
