Farmers' markets are a great place to buy fresh and locally grown food. These products are often offered for sale on the basis of weight. The scales used to weigh these products must meet the requirements of the Weights and Measures Act.
When you purchase goods on the basis of weight, you should check that the scale:
- has an inspection sticker, indicating that it has been certified as measuring accurately
- is level and has been installed on a stable surface
- is sheltered from environmental factors that may affect its accuracy
You also need to make sure that you can see the weighing operation and the weight indication on the scale.
The total price charged must be calculated based on the amount of product purchased only. The weight of containers and packaging must not be included in the calculation of the total price.
If you have doubts about the accuracy of a scale, you may file a complaint with Measurement Canada.
