Under which federal act is a pesticide label required?

A pesticide label is required under the Pest Control Products Act. This Act regulates the approval and use of pesticides in Canada and mandates that all registered pesticides must display a label that provides crucial information. This includes details about the product's use, the safety precautions necessary for handlers and the environment, and any restrictions on use. The labeling requirements are essential for ensuring that users apply the pesticide safely and effectively while also protecting human health and the environment.

The other acts mentioned may deal with environmental protection or pest management but do not specifically regulate pesticide labeling in the way that the Pest Control Products Act does. Therefore, the Pest Control Products Act is the key legislation that enforces the requirement for pesticide labels in Canada.
