Regulation of Measurement in Canada Today

After Canadian Confederation in 1867, the young Canadian government placed a large order with British makers to replace standards previously used by each province. The new sets were delivered in 1874 and this date appears on many of the original Canadian volume and mass standards. Since 1951 the primary standards have been maintained by the National Research Council’s (NRC) Institute for National Measurement Standards (INMS) in Ottawa. INMS is also responsible for developing the scientific means to establish the national measurement standards.

Legal enforcement of standards is assigned to Measurement Canada. They monitor compliance through a network of laboratories and inspectors with their standards ("secondary standards") regularly compared to the primary standards at NRC. When an inspector has tested and approved a measuring device, it receives a sticker, often seen on gas pumps or grocery store scales, authorizing it for commercial use.
