Under Canada’s Plant Protection Act, Plant Protection Regulations, the movement of both Dutch elm disease (DED) pathogens is regulated. Elms from a DED-infected province cannot be shipped to a disease-free province. Alberta and British Columbia are classified as DED-free.
Under the Agricultural Pests Act (APA), Pest and Nuisance Control Regulation (PNCR), both DED pathogens (Ophiostoma ulmi and Ophiostoma nova ulmi) – and the European and native elm bark beetles that carry them – are named declared pests in Alberta.
Under the Act and Regulation, all municipalities, counties and MDs in the province of Alberta have the responsibility and authority to prevent and control DED. See below for how the Act and Regulation outline these responsibilities.
Municipalities without DED bylaws
For municipalities with no DED bylaws in place, the APA provides a means for enforcement. Several sections of the APA and the Regulation can be applied. It is an offence not to take ‘active measures’ and not to follow an Inspector’s Notice which can be issued by an Agricultural Fieldman, community peace officer, a municipal officer that has dual municipal and provincial appointments or a pest inspector. They all can have the powers and responsibilities outlined under the APA Section 17 to enforce the DED prevention and control to the land owner.
Inspections and notices
APA Section 10 (1) The local authority of a municipality shall appoint a sufficient number of inspectors to carry out this Act and the regulations within the municipality. (2) Two or more local authorities may, (a) jointly appoint inspectors to act within the municipalities represented by the local authorities, and (b) enter into an agreement for the sharing of the costs of the inspectors appointed jointly. Pest Inspectors can be trained in advance to identify elm wood and DED symptoms and start surveys immediately on private property if DED is found.
When issuing an Inspector’s Notice, use the PNCR Form 2: Notice to Control Pests (DOC, 33 KB) found on page 11 must be used. Municipalities can add their municipal logo on the Form 2 but cannot change the wording. An Official Municipal Pest Inspector's Card would be issued to the appointed Pest Inspector by the municipality and must be shown upon request by the landowner. See also Schedule 1.1, Form 2 of the Pest and Nuisance Control Regulation (PNCR).
It is best to serve a notice by hand to the landowner. However, if this is not possible, then the notice can be left with someone (18 years or older) at the place of business or residence. If this is not possible, then the notice has to be mailed or posted on the infected land. In the first instance where a notice is hand delivered, the inspector can give a shorter time to rectify the issue. It is at the inspector’s judgement to decide when the pest needs to be controlled.
APA Section 20: If a third party has contravened the APA, the Minister may issue a Stop Order.
In order to prevent or control this deadly disease, all DED prevention and control are enforceable under the APA and must be followed.

Pest and Nuisance Control Regulation (PNCR)
Section 4 of the PNCR “Transactions, etc., in pests and infested matter”
This section prohibits “dispositions” of “infestable” items. Care must be taken when transporting an elm tree positively diagnosed as contaminated with DED to the disposal site. All tree material must be covered and secured, eliminating the chance of contaminating healthy elm trees.
- A person shall not import, purchase, sell or otherwise dispose of, transport, distribute or plant any infestable item that is infested or any pest without the prior written authorization to do so of a provincial inspector or, if the article is to be kept in Alberta, of a local inspector who is empowered to act in the local jurisdiction where it is to be kept.
See all DED forms and documents.
