All Canadians have a role to play in preventing the introduction and spread of invasive species in Canada, including the responsibility to report to the CFIA any known, suspected or potentially regulated pest plants. Phytosanitary measures taken with respect to regulated pest plants depend on the pathway by which the plant can enter or spread within Canada, the intended end-use, and the risk mitigation measures that are available.
Under the Plant Protection Act, the CFIA has the authority to restrict the import, sale, possession and movement of pest plants including weed seeds into and within Canada. Several of the species listed in this directive are also regulated as prohibited noxious weed seeds under the Weed Seeds Order, 2016 of the Seeds Act.
This directive communicates phytosanitary requirements intended to prevent the introduction and spread of plants regulated as pests by the CFIA. Introduction could include intentional pathways such as traditional food and medicine, plants for planting and seed, and unintentional pathways such as contaminants in seed, hay and straw, grain crops, crop residues, soil, machinery and equipment (for example, vehicle parts, metal products), handicrafts, and fresh produce. The CFIA's Invasive Plants Program was developed in recognition of the threats posed by pest plants to Canada's economy, society and environment.
Pest risk analyses provided the scientific rationale for regulating the pest plants included in this directive (listed in Appendix 1). Regulatory decisions are based on the best science that is available at the time and can be revised as more information about the species becomes available.
If a plant presents a significant risk to Canada's plant resource base, it will be considered for regulation using the pest risk analysis process. Stakeholders are encouraged to provide input on the plant species and on proposed regulatory options for risk management. Before a decision is made to regulate a plant as a pest, the CFIA will inform stakeholders throughout the process.
4.1 Regulated pest
All regulated pest plant species/taxa, including all propagative parts, are listed under Appendix 1 of this Directive. This includes plant species in and of themselves or as contaminants associated with other pathways.
4.2 Regulated articles
Regulated articles include plants designated as pests and anything contaminated or that could be contaminated by such pest plants, including but not limited to seed, general cargo, shipping materials, conveyances etc., will be subject to regulatory control or action.
4.3 Regulated areas
Regulatory measures may be in place wherever regulated pests are or may be located in Canada, from small properties to entire provinces. Areas concerned and associated measures may be specified in legislative notices issued by the CFIA to the owners or to persons in possession, care or control of a pest or commodity.
Regulated areas may also be defined in Ministerial Orders made under the Plant Protection Act, or be specified in the schedules to the Plant Protection Regulations. As needed, this directive will be updated to further communicate regulated areas, as well as any associated prohibitions or restrictions.
Notwithstanding the above, note that the general prohibition specified in subsection 6(1) of the Plant Protection Act applies to the regulated pests and articles that are within the scope of this directive:
"Except as permitted under this Act or the regulations, no person shall move, grow, raise, culture or produce any thing that there are reasonable grounds to believe is a pest, that is or could be infested with a pest or that constitutes or could constitute a biological obstacle to the control of a pest."
This directive is intended for use by importers, individuals handling or moving these regulated articles in regulated areas, agricultural, horticultural and forestry industries, the Canada Border Services Agency, the CFIA, other government departments and the public.
6.0 General requirements
Individuals or companies can confirm the phytosanitary requirements with the CFIA through one or more of the following means:
- contacting their local CFIA office
- apply for an import permit
- consulting the List of Pests Regulated by CanadaFootnote 1
- consulting the Automated Import Reference SystemFootnote 1
Plant species that have previously been imported into Canada, but that have since been determined by the CFIA to be regulated pests, may be subject to import and domestic movement restrictions.
The phytosanitary requirements stipulated in this directive are specific to controlling the entry and spread of regulated pest plants only. Additional requirements may exist for other pests and commodities under other federal, provincial or municipal regulations.
All imported shipments must be free from regulated pest plants and meet Canadian phytosanitary requirements. Importation of regulated pest plants and their propagative parts is prohibited unless authorized in a CFIA-issued Import Permit.
Import of devitalized material may be accepted if regulated pest plants or plant parts have been rendered non-viable. Prior approval is required before import, an application should be presented to the CFIA in accordance with policy directive D-97-04: Application, procedures, issuance and use of a permit to import under the Plant Protection Act. An acceptable treatment method should result in complete devitalization. Any devitalization treatment proposed should be done at origin prior to importation and proof of treatment must accompany the shipment.
6.2 Domestic movement
Domestic movement of regulated pest plants and their propagative parts is prohibited, without prior CFIA approval. Things contaminated with such species are also subject to domestic phytosanitary measures. These measures may include movement restrictions, restriction of use, treatment, surveillance and monitoring. For requests related to pest plants sourced within Canada, please contact the CFIA's Invasive Alien Species and Domestic Programs at: firstname.lastname@example.org.
6.3 Special purposes
The CFIA may consider and authorize in writing the import, domestic transfer or conduct of other activities in respect of a regulated pest plant for scientific research, educational, processing, industrial or exhibition purposes. The determination by the CFIA to permit such activities will include consideration of an applicant's ability and willingness to comply with phytosanitary conditions and to take every precaution to prevent the spread of the pest plants.
To request the import of pest plants, an application should be presented to the CFIA in accordance with policy directive D-97-04: Application, procedures, issuance and use of a permit to import under the Plant Protection Act, and to request a domestic movement of a pest plant please contact the CFIA's Invasive Alien Species and Domestic Programs at: email@example.com.
Pest plants or consignments that are contaminated with regulated plants or otherwise non-compliant may be subject to CFIA regulatory action. This may include, the shipment being removed from Canada, destroyed or ordered to be treated to prevent the spread of pests prior to disposal. Import permits and written authorizations may be revoked if the person to whom a permit or authorization has been issued does not comply with the conditions of the permit or authorization or the provisions of the Plant Protection Act and Regulations. The importer is responsible for any and all costs relating to treatment, disposal, removal or re-routing, including costs incurred by the CFIA to monitor the action taken.
Notifications of non-compliance will be issued to the exporting country for imports found to be non-compliant.
8.1 Other legislative authorities that may apply
In additional to authorities specified in section 1.0, importation of plants and plant products may also be subject to other Acts and Regulations. These may include:
CFIA Acts and Regulations:
- Seeds Act and Seeds Regulations, Weed Seeds Order
- Feeds Act and Feeds Regulations, and
- Health of Animals Act and Health of Animals Regulations
