Weights and Measures Act (Canada)

The Weights and Measures Act (Canada) is federal legislation governing the standardization and accuracy of weighing and measuring devices used in trade within Canada. The primary goal of the Act is to ensure fairness and accuracy in commercial transactions where quantity is a factor.

The Act establishes the legal units of measurement in Canada, primarily based on the International System of Units (SI), also known as the metric system. It specifies requirements for the design, construction, and performance of weighing and measuring devices. These requirements aim to prevent fraud and protect consumers and businesses alike.

The Weights and Measures Act is administered by Measurement Canada, a special operating agency of Innovation, Science and Economic Development Canada (ISED). Measurement Canada is responsible for verifying and approving weighing and measuring devices, inspecting devices in use, and enforcing the regulations under the Act. This includes setting standards for device accuracy, conducting routine inspections of commercial devices, and investigating complaints related to inaccurate measurements.

Devices covered by the Act include scales used in grocery stores and other retail outlets, gas pumps at service stations, and liquid and dry measures used in various industries. The Act prohibits the use of unapproved or inaccurate weighing and measuring devices in trade. It also outlines penalties for violations, including fines and potential prosecution.

Amendments to the Act have been made over time to reflect technological advancements and changes in measurement standards. These amendments ensure the Act remains relevant and effective in maintaining fair and accurate measurement practices across Canada. The legislation plays a crucial role in fostering consumer confidence and promoting a fair and competitive marketplace.
