As soil is a major carrier of invasive species and plant and animal diseases, vehicles, equipment and other goods arriving at the Canadian border that are contaminated with soil are not admissible into Canada.
Non-compliant goods are refused entry and ordered removed from Canada at the first point of arrival under the authority of the Plant Protection Act and the Health of Animals Act.
Some exceptions for cleaning the contamination at the first point of arrival may be granted, under rigorous conditions.
Whether the goods are returned or cleaned in Canada, all additional costs will be at the expense of the importer.
Some items which could potentially contaminated with soil and soil-related matter include vehicles, containers, equipment, logs/lumber, blocks of stone, machinery and tools.
