In Canada, firewood is usually sold at the retail level in the following two ways:
In bulk (larger quantities): Most bulk firewood (split or whole roundwood) is sold by stacked volume. The declaration and accuracy of the delivered quantity are regulated by the Weights and Measures Act and Regulations, which are administered by Measurement Canada.
In bags or boxes (smaller quantities): Firewood is also sold at retail in bags or boxes by stacked volume expressed in cubic decimetres (dm3). Accuracy and labelling requirements for packaged firewood are found in the Consumer Packaging and Labelling Act and Regulations, which are administered by the Competition Bureau.
