Report a tree pest or disease in Canada: who the agency names

This page reports what the official source says. It is not legal advice: ask the office named here. It sets out how the Canadian Food Inspection Agency, called CFIA, describes reporting a suspected tree pest or disease, with the date each CFIA page shows. For the wider country-by-country picture see tree pests and diseases.

Who takes the report

CFIA is the federal agency for plant health. Its pest pages each carry a report link that opens the same online contact form. That form is on the Contact CFIA online page, which says it is for reporting a food, plant or animal concern or asking for information. The page also gives a telephone route for anyone who prefers not to use the form: 1-800-442-2342 or 1-613-773-2342, and a teletypewriter line at 1-800-465-7735. It shows a modified date of November 14, 2022.

What the agency asks the reporter to include

The contact page asks people to pick the best option from its drop-down menus, to be as detailed as possible, to avoid acronyms, and to say where the issue is when reporting a plant pest. The form asks whether the person writes as a member of the general public or as industry, and it has a forest pests choice under its plant business sectors. The form also asks for a name, an email address and, for industry senders, a business name. No pest page read for this page lists photographs or a specimen as a requirement.

Provinces

The CFIA pages read for this page route every report to the federal form. The spongy moth page links to the British Columbia Ministry of Forests page for that province's own work, but it gives no provincial reporting line. This page therefore lists no provincial route.

Pests the agency names

On the CFIA firewood page, dated September 22, 2026, the agency names four pests to watch for: emerald ash borer, Asian longhorned beetle, brown spruce longhorn beetle and spongy moth. It says the brown spruce longhorn beetle has been found in Nova Scotia and New Brunswick. The firewood page also says that moving firewood from places where regulated pests have been found can break the Plant Protection Act. For emerald ash borer, the CFIA pest page lists the regulated areas in Ontario, Quebec, New Brunswick, Manitoba, Nova Scotia and British Columbia.

How the pest pages treat tools, vehicles and wood is laid out side by side in the biosecurity table by pest. The guides on emerald ash borer and spongy moth give the regulated areas in detail.
