2018-2019 Plant Protection Survey Report

The objectives of the Plant Protection program within the Canadian Food Inspection Agency (CFIA) are to prevent the introduction and spread within Canada of plant pests of quarantine significance, to detect and control or eradicate designated plant pests in Canada, and to certify plants and plant products for domestic and export trade.

Plant protection surveys support the Plant Protection Program in a number of ways. They help to detect new populations of quarantine pests or potential quarantine pests being considered for regulation. Delimitation surveys are also conducted to determine the range of pest populations with limited distributions in Canada (ISPM no 08). Surveillance data allows Canada to maintain claims of Pest Free Area (ISPM no 04), Pest Free Place of Production & Pest Free Production Site (ISPM no 10) status, and supports our ability to meet a number of international phytosanitary standards under the International Plant Protection Convention. Surveys provide information in support of import, export and domestic regulatory programs. They are a key contribution to policy development and trade negotiations. In all cases, reliable and accurate pest distribution data provides the basis for sound regulatory decisions. The information may be used for a variety of purposes, including reasons for removing, altering, or even not establishing a quarantine regulation. Plant pest surveys are also an integral part of control and eradication programs (ISPM no 09).

In the 2018-2019 fiscal year (April 1, 2018 to March 31, 2019), the CFIA conducted surveys for the plant pests listed below.

The CFIA's Plant Health Surveillance Unit is also dedicated to preventative science and research that supports risk mitigation and early detection. Research projects in which the PHSU have been involved in 2018-2019 include:

Finally, the unit is committed to building and maintaining partnerships and networks through innovative education, outreach and awareness strategies that strengthen networks and build surveillance capacity.

The CFIA has worked closely with its partners, including provinces and municipalities to expand the reach of surveillance efforts for gypsy moth and emerald ash borer.There were a total of 483 survey sites delivered by partner organizations. Partnerships with the Invasive Species Centre, Ontario, Parks Canada Agency and the Canadian Council on Invasive Species have continued and several Memorandums of Understanding for data sharing with provinces have been established. The unit regularly holds training and outreach events with the public and stakeholders, in addition to providing internal training for CFIA inspectors. Please contact the Plant Health Surveillance Unit if you or your organization would like to receive support for training or public outreach events.
